Headphone Question

How are headphones/earbuds powered? Is power sent through the audio port? If so, how many volts go through? This question how always wondered me. Because earbuds are basically mini speakers and speakers require power, so shouldn't headphones need at least a little power?

Fixing a broken headphone port? (iPod touch 3g)? Answered

       I've had an ipod touch for a little over a year now and the left headphone output is no longer audible.  I believe that it is due to a loose or slightly bent contact inside of my iPod, because if i wiggle my headphone connector in the iPod's female audio jack the left side audio will turn on and off.  I have contacted Apple about the iPod (no longer under warranty) and have been told that the cases for iPod touches are crimped together, and so there is no way for them to open the iPod and replace the port.          Any suggestions as to how i could fix my problem? I've been thinking of using a dental tool to pull the contact that is causing me issues outwards, but decided i would ask around before potentially worsening my port. Thanks! -Geo

Old headphones made into speakers

Hey guys. If you want to cur the crap skip to the third paragraph. So I found this speaker in a voice recorded message greetings card thing and it's pretty loud for it's size, so I decided to put it in place of a headphone on my old iPod headphones. I Took apart the right bud and soldered the + - wires to the speaker, and it worked first time. My problem is now that some songs have say guitar coming through the right speaker and bass through the left. I decided to try and mount the speaker below the split. The thing is, I'm not sure which are the + and - wires. I know that speakers work by changing between + and - to make the diaphragm move, but when I mounted the speaker where the ear bud was, it was easy as there were 2 wires. Below the split there are 4. So my question is. Does it matter what 2 wires I pair together to solder at one port? The colours are Blue, Red, Green, and Red/Green intwined.

How do I use a phones headphone jack as an I/O port? Answered

I am thinking about making a device which would essentially be an IR led connected to a cell phones headphone jack and function as an IR remote. I am also planning on having a separate IR receiver that could record signals from a remote.  This isn't so much a question of pin-outs, as it is a question of supporting components and code. This is a two part question.  1. Would it be possible to connect the LED straight to the headphone jack and have it function correctly. What I mean is do the Hz match, is there enough power to the led to get it to work, etc. or would I need some sort of IC between the LED and Headphone jack. I know that I need a chip with the receiver. 2. How would I get the whole thing to work along the lines of the code. Could I just record an audio file with the IR receiver and play it back with the IR LED? I am wondering how to to this without a bunch of supporting components. Thanks!

How to record from a separate computer's Line-out? Answered

I have a bunch of midi files on an old Windows machine and I would like to make mp3 recordings of them playing on the machine's old soundcard.  I have an old version of Audacity on the computer, but the machine isn't powerful enough to make a good recording of the sound sent to the machine's Line-out while playing a midi. I would like to connect the Line-out to another computer's microphone port and record using a modern version of Audacity on a modern computer.  When I connect a double-headed headphone cord into both the Line-out of the old machine and the microphone port of the new machine, the new computer reads the microphone as being unplugged (it thinks there's nothing plugged into the port even though the male headphone jack is in). The old computer is a Dell with Windows 98.  The new one is a Lenovo Thinkpad T520 running both Linux Mint 18 and Windows 10 (both systems show the microphone port as being unplugged with the double-male cable but read a microphone).  I have an adapter for the dual-output/input port on the Thinkpad, and I know the microphone port works fine with an actual microphone.  Does anyone know why my computer will register input from a microphone but not from the other computer's Line-out and how I might get it to receive input from the old computer?

Where is the static comming from? Answered

I recently began experimenting with recording my guitar. I've tried plugging my guitar straight into the line in port of my laptop via a 1/4" cable and 1/4-1/8 adapter. I then record it in audacity with no added effects or gain or whatever. I liked it but it did not seem as good as it should have been. I tried connecting my guitar to my amplifier and connecting my amplifier via the headphone port and a 1/8" cable to the line in port. It sounded PERFECT except that there was a constant anoying string of static being recorded. I turned down the gain on my amp but then my laptop would not get a signal. I experimented with a bunch of different combonations of gain and volume but i cannot get rid of the static. I expect it's because my amp does not have any output other than the speakers or headphones. I'm just wondering if there is anything i can do other than get or borrow an amp with lower noise.

Casio pocket Tv: Tv-1900B info/suggestions on uses?

I just received a casio pocket television model: Tv -1900b, produced somewhere in the late 80-mid 90's(cannot find year) as a gift from my sister, purchased for 2.99 from goodwill, she bought it because I like vintage electronics, and thought it was useable as she was not aware of the difference between dtv and analog, and took the label heading that it received working channels for true, from my research it appears to be functioning but is receiving no signal due to the dtv transition. this is my problem, I am trying to figure out ways around not having an available analog broadcast to pick up, and can not find much info for this tv model online, not even part labels manuals or specs, Im wondering what my options for use or connecting it to another device are.. There is what appears to be an extra headphone sized jack/connector at the top next to the speaker, and a headphone plug does fit into it... but the label for it is long gone, so I do not know if it is an external antenna connection, external composite video in port, external video out port, or a service port of some kind, as it is right next to the rod antenna  screw connection, what exactly is it, and can it be used for an external video/sound input connection?, I see that  on other models before and after this one it can be used as a video/audio input, when utilized with a rca to headphone adapter cord but that does not tell me for sure if mine has that ability. What are my options with this?, I have some technologic know-how, but could not build my own signal transmitter, oscilloscope, built in jack, etc from scratch. is this model capable of easy external connections?, is the extra hole for an antenna input, video input or both?, can a box, dvd or vcr be connected, also is wrapping wire around the antenna and then connecting to the coaxial output on an external device feasible? Iv seen it work on other pocket tv's on the internet but dont know about the true signal quality/effeniency I would be able to make most physical external connection adapters myself, or, are adapters other then the headphone to rca adapters sold to remedy the problem of having a rod antenna and little to no external hook-ups? p.s I am not opposed to having it constantly wired/tethered to a much larger device, as it would be used for a novelty or in a small area where a larger unit would be to big or unweildy, like next to a bed, spot at the table, etc, also I would probably not use it for cctv or similar as I have little to no use for such things the picture included is not of my actual item, but the same model and version, for reference purposes I appreciate any help, as it appears to be functioning it would be a shame to not find a use for .

Digital crossover..?

Well people, since no one want's to help me 'Build' a hardware crossover, perhaps someone on here might know of how I could use one of my spare laptops and feed my input signal to my amp into the mic port and equalize it/cut off the high freq's and send it back out the headphone jack. Surely there's some kind of program that would give me control over the output signal like giving it a sharp cutoff at 60hz or something like that.

Old Stereo headset found, but it has an odd array of solder points and i can't seem to get any sound, any ideas? Answered

Hi there! I recently found two old sony headphone speakers, but i can't seem to get any sound out of them. It's a standard L/R speaker set that was enclosed into each ear piece. The odd thing is though that there are 8 solder points on the speaker pieces. One which is black blobbed and two that are white blobbed (i'm assuming it's to prevent shorts). Two wires are connected to two of the solder points (they don't seem insulated though...) I've tried various connection methods to make them produce any kind of sound, but nothing happens. I'm assuming they still work because they look intact, but...well any ideas? I don't have any expertice with audio equipment, but i do have basic electronics experience... I know it's kind of an odd question, but i'd really like to use these speakers and i wanted to make sure i wasn't doing anything wrong. Basically i've been trying to connect various music players to a mini jack port using a microphone mini jack cable (seems to work for all other purposes) and then tried to connect the speaker wires to the jack port solder points (in various ways).I'm probably going to feel really stupid as the answer is probably really simple x3 I hope it makes sense!i should probably specify that the main problem is that i can't get any audio output from them, aka. they're silent no matter what i hook them up to

Do Tritton AX PROS still have surround when plugged into analog(on Xbox 360)?

Hello, I've been looking into buying a better pair of headphones to replace my dying X11s, and came across the Tritton AX PROS(the ones for consoles, not the cheaper PC/Mac only ones). Dad and I went over all the stuff today, and we've run into a problem: The only open ports on my Xbox 360 HDMI dongle are analog. Before you say "well, just unplug the optical," those optical cables are FRAGILE. Like, you bump 'em the wrong way or plug in/take out the wrong way, you've got a broken cable. And I can't afford to do that sort of thing, because if it breaks, then Rock Band(which I play through our surround sound system) is pretty much done for. I was wondering if you can do surround sound through the analog(I know you normally can't), because of the little box thing it comes with. Best answer gets a cookie and subscription. Also, I don't want speculation, I want fact.

How can I wire a recorder cut-in box?

So, a little background: I'm a reporter, and I do a lot of telephone interviewing. There's currently not an app that works reliably for my phone to record both sides of a call, and given that I already have a very nice standalone voice recorder (sony ICD820) that has line in/line out functionality, I'd like to have a way to run the signal from my phone into the recorder, record it, and then pass it on to a headset with a mic on it. The problem is that the recorder only has 3.5 mm stereo in/out (TRS), with no separate mic channel, so if I connect the (TRRS - mic/l/r/ground) cable from my phone directly into the recorder, then connect my headset to the 'line out' port, it ends up distorting badly, and not recording the mic channel. As a temporary solution I A) use two "Y" cables (one connected to the phone, and one to my headset) to split the mic from the audio channels, then B) feed the audio channels into and back out of the line in/out ports on the recorder, and then C) use a coupler to mate the two mic channels. This puts the recorder in-line on the audio channel(s) only, and routes the mic channel directly from my phone to my headset (picture attached). This works great, but it's bulky and delicate, and obviously only records the incoming side of the conversation.  THE QUESTION: How can I wire a box that will give me the ability to "cut in" a recorder on a TRRS source, which is delivering (potentially) stereo audio channels along with a mic channel - ie, up to three channels - so that the recorder is recording all three channells? (note: it does not matter if some/all of the channels are merged). WOULD IT WORK TO wire a box that A) summed the Left and Right channels from the phone using resistors on each channel (see the picture in the link), and B) fed the summed audio and the mic lines into the Left and Right pins of a TRS plug, respectively, to give the recorder a stereo source? I have put together a crude diagram of what I think this could look like (note that the diagram includes a DPDT switch to 'cut in' the recorder, but I would likely omit this in the final design for simplicity). Additional question: I have seen wildly varying info on what size resistors to use on the summing circuit, and also conflicting information as to whether I need a third on the ground (???). The simplest I have seen is just using a 1K resistor on each of the incoming channels. Given that these are just standard headphone/passive mic voltages, what size resistors would I need, and where in the circuit? Link to the simplest 'summing box' diagram I hve found for this type of application (top image): http://techtalk.parts-express.com/forum/tech-talk-forum/60443-stereo-to-mono-summing-circuit

What's the best way to bend coat hanger wire, for making a DIY GameKlip?

So I discovered my Samsung Galaxy S3 supports USB gamepads.  Well long story short, I quickly hacked apart an old original Xbox controller, replaced its 10 foot xbox cable with a 1 inch USB cable, and it works GREAT in most gamepad-supported Android games like Dead Trigger and Shadowgun.  The next obvious move was to make a holder to attach my phone to the gamepad, to have a portable gaming device, like an nVidia Shield.  Now I know commercial solutions exist, like the Gameklip, but they're all designed for the PS3 controller, which I don't have. So I've attached pictures of my first two versions.  The first picture showing the regular coat hanger wire wrapped in black electrical tape.  It held the phone just fine, but it was butt ugly, because I used electrical tape to protect the phone from the steel coat hanger wire.  So I made a second one (2nd picture), using a rubber/plastic coated coat hanger, thinking it would look better, because I wouldn't need to wrap it in electrical tape. Well the problem is that I'm so horribly bad at bending wire, and at planning, and measuring, that I had to make so many corrections, that it too looks butt ugly.  It's a completely different design than the first one, for starters.  I can never think of how to design these things on paper.  I always just get a rough idea in my head, and then play it by ear as I go along.  But because steel coat hanger wire is so incredibly tough, every time I try to bend it with pliers, or a vice grip, I end up damaging the nice plastic coating, making it look ugly.  Multiply that by the number of times I had to make corrections, and well, you can see the result.  The second design is the one I'd like to stick with, however.  Mechanically speaking, it is perfect.  Two nubs on the bottom, and a nub on the left and right sides, hold the phone in place using gravity and friction.  Then the whole thing uses spring-tension to compress the left and right nubs inwards, squeezing the phone in place, but without letting these nubs get in the way of the USB port or the headphone port.  One can adjust the width and tension of these left and right nubs, just by squeezing or stretching them apart, to fit different sized phones and cases.  Finally, two support legs are left at the end of the wire to easily place the whole thing on a table. Both versions are attached to the controller in the same way:  I started with two loops, as small as I could make them, right next to each other.  Then I just bolt the whole thing to the controller through those two loops, and two holes I've drilled in the controller's memory slot.  It's an incredible pain in the ass to try and get the nut and washer in the tiny amount of space in that memory card slot, but I managed to do it twice. I want to build a third, good looking one.  So now I've gone out and invested in some proper, straight steel wire (of the same thickness and stiffness as the coat hanger wire), and some heat-shrink tubing to protect the phone from the steel.  But I need advice on how to do this properly, so that it looks good.  The only way I can use the heat-shrink tubing, is to put it on FIRST, BEFORE bending the wire.  I couldn't possibly imagine how to do it AFTER bending the wire.  But the problem is, I'm worried that my vice grips/pliers will damage it the same way they damaged the plastic coating of the coat hanger. Any suggestions/tips would be greatly appreciated!

How do I get rid of the Hummmmmmm? Answered

In my latest project I've installed an iVO-Sound m1050 4GB portable media player in to a Magnavox D8443 Power Players cassette bay.You can hear a distinct Hummmmm in the speakers. If you touch the control buttons for the MP3 player the Hummmmm gets louder. The Hummmmm increases when you turn up the volume. Sometimes there is almost like a static-like sound to the higher audio frequencies. Sometimes the sound is more tinny. It's almost like a charge is building up maybe. When the music is playing the hum is less noticeable. The hum seems to get worse progressively the more you use the displaced controls.All controls that were displaced have been mounted in the old cassette players buttons. The tape circuits are off. The MP3 player switches with the Radio to the Amp. There is a charger but it was disconnected for now. The displaced USB port is extended to the back of the box where it also switches to the charger.What I have tried so far:- I have hooked up an Alternative MP3 player to the new Aux Input RCAs that also switch with the Radio to the Amp and the External MP3 player sounds great!- I made sure the tape heads and wires were all removed from the cassette compartment area.- I originally connected the audio with a headphone jack but now it is hardwired.- I removed the Metal back case of the MP3 player and that helped a bit. All the wiring was strung through the metal casing.- I have Tried an Audio System Ground Loop Isolator between the MP3 player and the Amp. That took away most of the hum but made the sound very "tinny" with almost no Bass.- I tried Ferrites on the Audio cable between the MP3 player and the Amp and the Power Cord and a number of other places. There was no discernible change. The cables weren't long enough to loop so I used several ferrites in series.- I have order a couple Audio Transformers so I can try and use them like the ground loop isolator if it is an impedance problem but I don't expect much different a result.- I have plugged the AC cord into it's own circuit on my breaker box and that seems to help a little.(My original MP3 player - boombox installation turned out great. The main difference is that most of the buttons were on the face of the MP3 player and only two buttons were displaced to the front of the box and that was the power and reset. The charger made horrible interference racket but you could just listen to the radio while it charged.)

My idea for the iRobot Challenge

Okay, I hope this is good :-D!Well, my idea is actually several ideas, but they all share the same theme:Chumby + iRobot's Create(And yes, I already have a Chumby)This might sound crazy, like adding speakers to an iPod, but it is defiantly possible.Since I don't have one, I can't say, for 100% sure, exactly how I'm going to make it work, but I have plenty of ideas. (I'll work backwards)The robot has 25 inputs. My last resort would to be to hook up the headphone jack to 2 of those inputs, and send signals by pulsing sound, similar to the way TV remotes pulse light. This is guaranteed to work, because Flash (which I'll be using in the project itself), can access the speaker. For robot-to-Chumby communication, there is the Microphone.Next up, is building this Sensor Package module that you can use with your Chumby. This would also work great, since it has 8 digital outputs, 8 digital inputs, and 12 motor drivers (which I could probably use as more outputs). However, I haven't found out yet if you can access this from flash, so it may become an issue. However, it seems more likely than the following:My first attempt is to tap into unused (in my setup) pins on the "Chumbilical", the main wire that connects the sensors to the main unit. This includes a USB port. Again, I am doubtful that Flash can access these, but I may be able to figure something out in Java or Phython.So I've hooked this up to the Chumby, now what? There are so many possibilities, because my new robot will now have various sensors from the Chumby, along with it's touch-screen display and WiFi.One could start with the "physical alarm clock", an alarm clock that you'd chase down to turn off. (As seen on ThinkGeek, it's "Clocky") Although, this is very much underusing it's capabilities. Next, of course, is the email alert system. When you're not on the computer, sometimes something external is a nice reminder :P In a workplace, lets assume someone gets an email every minute. This should be perfect timing for it to drive from cubical-to-cubical on every email. It would, however, be forced to rely on relative positioning.After the frivolous, this could be set up as a system where the Chumby would display images of me, streamed form a webcam, as I control the robot. Attached, would also be a webcam, streaming from the robot to my computer. (This was done with the Make: controller and a MacBook) (And yes, the Chumby has a HTTP server in it, and can support some webcams!)Heck! Why not have all three running at once :PI defiantly think the first 2 are not Instructable-worthy, but I wanted to give some other examples. The 3rd would be the one I do ;-) It would be much lest costly than the full-sized version, this being under $350. (I'm guessing that's about 1/3rd the cost?)Thanks for considering me as someone worthy of this "scholarship", I know I will use it over and over again if I end up getting it :D

2 computer builds: one budget computer system, and mid range gaming system. is everything compatible with each other?

I want to build a $200-$250 ultra budget computer system as my first build, to get the ropes, then after i get it working, and all, then move on and build another, much more powerful  $700-$750 gaming / video editing PC. however, i need help with making sure everything works together, as well as suggestions and tips please. i highly appreciate if you answer in detail everything i asked, that answer will get best answer from me. a will add details as i learn more about what i am really getting into. i bolded all my unanswered questions. (i decided on just making to separate builds,  originally i planed to make i cheap computer, with a good mobo, then expand on it. however i just decided it is better to make two separate builds.) 1) what advantages can i get out of a good housing/case? i prefer to use just the case i have right now, the old one from my old HP pavilion a1747c. it has several card readers and a few usb ports on the front, headphone jack, mic jack, some jack labeled 1394, 2 expansion bays (one of which with a DVD drive in it) 2) i plan on using a motherboard with a chipset that allows for: overclocking the CPU, RAM, and separate video card; as well as support for intel HD graphics; and of coarse uses the LGA-1155 socket. for less than $130.  ) is in any good? can someone list a few good afordable boards that will do what i listed above? her are a few i have in mind. is ASRock a good company? ASRock Z77 Extreme4 LGA 1155 Intel Z77 ATX Intel Mobo <-- i am leaning towards this one. ASRock Z77 Pro4 LGA 1155 Intel Z77                                      3) for simple stuff like wifi, bluetooth, etc; do i need to buy those separably (for the motherboard)? do they use PCI slots? if not, can i use the old WiFi adapter from my old computer? id rather not use external but if i have to, i will. so i assume if i want front facing USB 3.0 slots i need a new case, right? --------------------------------------------------------------------------------------------------------------------------------- 4) here are the parts for my first build. please tell me if you see a problem with the selection    CASE: ------Cooler Master RC-343-KKN1  MOBO:------ ASRock H61M-DGS LGA 1155 Intel H61 Micro ATX (any better value out there)?  CPU: --------Pentium G620 (lga-1155) (can you best it within  $60?)

Tracking down the speed problems on a laptop.

I've copied the conversation here so we could remove the information from the original instructable's comments.  I figure this would also be of some interest to other forum viewers who may have similar problems, or may be able to chip in. The long and short of it is, 92033 (Ed) has a refurbished laptop that takes literal hours to run a YouTube video on.  I suspect that it's due to a bottleneck with his internet connection.  Here's the conversation thus far: ---------------------------------------------------------------- 92033 (Ed): Thank you kindly for your prompt reply...appreciate it very much. I came across this site by accident in searching for something else and now I'm 'hooked' on it. :) So far I've read over 400 archived posts (whew)...as well as looking at the videos. The videos are somewhat of a problem because this new laptop only has 512 mg memory...LOOOOOng time to load. For example...to watch a SLOW 5-minute You Tube video takes 5-1/2 HOURS to load...keeps showing a couple words at a time...need to get two new memory chips to upgrade to 2gb. Thanks again...Take care. ---------------------------------------------------------------- eddems: I think you're basic download speed is killing ya, not the laptop. check you're speed at Internetfrog.com, if you see the link near the bottom for the old test, run it, I like it's graph of upload and download speed much better. ---------------------------------------------------------------- 92033: Thanks much. I'll check it out. I ordered a 1gb SDRAM Memory chip which just arrived yesterday. Hope this speeds things up a bit. ---------------------------------------------------------------- harley_rly: i hear u man, my computer is hopped up, but i live out in the sticks and have dialup...i only get 24kbps at most :( ---------------------------------------------------------------- 92033: Maybe there's hope for 'us' yet. :-) I phoned Tiger Direct to see cost of an upgrading memory chip to go from 512mg to 1-1/2gb. The guy I talked to suggested I get "PC TUNEUP 2.0" which bypasses the Windows Operating System (I'm using Windows XP Pro) and speeds up the system. I gave it a try and ordered the CD (cost $39.98 - $44.77 postpaid). It hasn't arrived yet but will let you know if it helps as he claims it will. He said that if I just ordered a 1gb memory chip my system wouldn't notice much improvement as it is, but this CD should do the trick. THEN...when I DO order the Memory chip(s) to get total of 2gb my system should zip through like a rocket with the CD just ordered. I'll let you know when I get the CD and about the results. Just hope I haven't thrown forty-five bucks to the wind. Thanks for the contact...appreciate hearing from you. TAKE CARE. ~ ED ---------------------------------------------------------------- Javin007: PC Tune-Up "bypasses the Windows Operating System?" This guy fed you a load of crap. (I work on computers for a living.) PC Tune-Up does nothing more than clean up registries, defragment harddrives (if your OS even needs it, some don't) and keeps drivers up to date (which you could do manually.) That guy's an idiot, or just a liar. Could be both. Unless you were buying PC Tuneup 2.0 from Tiger Direct, in which case we can add "sleazy salesman" to that. What are the specs of the laptop? Go to Start/Run and type in DXDIAG. This will give you a quick snapshot of the specs. Specifically, I'm curious as to the processor speed/type. For a 5 1/2 hour "load" you're more likely looking at network slowdown issues (although 512 megs for XP is WAYYYY too little. I HATE when they put PCs together like that). The RAM upgrade will show significant speed increases, but no improvement with YouTube videos or other downloads. I'm glad to see you are returning the CD. ---------------------------------------------------------------- 92033: Thanks much for your input...appreciate it very much. I checked the DXDIAG as you recommended. Here's the info on it: IBM ThinPad Laptop PC. Model # 23738TU. Intel Premium M 1.70GHZ. 512mb SDRAM Memory chip.Page File- 351mb used,513 mb available. Direct Version-Directx 9.00 (4.09.0000.0904). 512 mb SDRAM-Actual 212 Ram. AVAST Anti-Virus. MS Windows XP-PRO.. Dialup Speed-40kbps. PC2700 SDRAM 512mb Memory Chip installed. I ordered 1bb memory chip which arrived yesterday. Now I have to figure out HOW to remove the bottom of this laptop to install it...lotta small screws on it. :-) Oh, total memory shows 32mb. I don't know if this means much to you. I note your comment that the added RAM memory WONT (?) speed up loading YouTube videos? Is that correct? If so, why not? Thanks again. Take care. ~ ED ---------------------------------------------------------------- Javin007: :) At the risk of boring too many people, here's how memory in a PC works: You have two kinds of memory: RAM, and Hard Drive (technically there's three, as there's also onboard video RAM on video cards, but this is primarily used for 3D video game textures, so can be mostly ignored.) Your harddrive's read/write speed is determined by the type of harddrive it is (most are SATA now) and the rotation speed (most are 7200 RPM, though the specs for your system say yours is only 5400 RPM, but there are 10, 15, and even 20K rpm models out there that are exponentially more expensive.) No matter what, harddrive memory will always be degrees slower than RAM. RAM on the other hand is a small chunk of memory that is "temporary" memory, but very fast. Its speed is determined by the type of RAM (DDR2 being the current common one for notebooks, though DDR3 is available with some motherboards (you can ignore this, though, as you can only handle 2 gigs max of DDR with your system). The motherboard will determine the limits for the RAM that can be installed.) When running *ANYTHING* on your computer, and I mean ANYTHING, it must first be loaded into RAM to be accessed by the CPU. The computer doesn't directly access the harddrive. So this means when your operating system is loaded (Windows XP) the entirety of all running processes for the OS have to be loaded into RAM. Now, Microsoft claims that Windows XP only requires a minimum of 64 megs of RAM, but recommends 128 megs. I challenge you to find me a Windows XP system that only uses 128 megs out of the box. It's not atypical for an XP system to chew through all 512 megs of your RAM, leaving no RAM available for other applications. (Interestingly, the default setup for your laptop is only 256 megs of RAM, yet yours is reporting 512.) What happens when there's no RAM left? The system has to then start trading things into what is called "Virtual Memory." VM is nothing more than a file on the harddrive that will temporarily hold information that SHOULD be in RAM, so the RAM can load more info. For instance, say you have a process that's using RAM, but you want to watch your YouTube video. As the video is ready to play, the system will take the other process's data that's in RAM, write it to the harddrive, load your video into RAM in its place, play a portion of it, write the video to the harddrive, load the data for the process to RAM, let it run for a split second (so it doesn't lock up), write it back to the harddrive, load your video into RAM and play a short clip, etc. etc. etc. The result of low RAM on your system is that applications will open slowly (seconds or minutes, instead of instantly or a few seconds) and they will seem slow to respond, will stutter, etc. With enough RAM, your system can freely open as much as it needs into RAM, and ignore the virtual memory and all the slowdowns that it causes. Now, all of this being said, NO lack of RAM will cause a streaming video to take 5 1/2 hours to play. This is 100% going to be related to your downspeed. (Go to www.speedtest.net and post your results.) RAM slowdowns tend to be most noticeable when shutting down, or starting up your computer, apps will open a little more slowly, they will be slower to respond to button clicks, and video will be very choppy. Anything that is causing a YouTube video to take HOURS will be due to the system simply waiting to get the video in the first place. RAM wouldn't slow down the receiving of the video, but it would cause the video to play weird once it's downloaded. So, all this being said, here's the summary: Your system has a 1.7 Ghz processor, and your RAM is most likely 333 Mhz DDR. If you bump your memory up to a gig, you should see a pretty significant improvement in that your computer will, overall, just "feel" faster. It'll be more responsive, and working with large documents will be many, many times faster. This won't, however, affect your YouTube experience (unless you were getting jittery video often, not the same as "buffering" video.) If you see "buffering" for a long time, your internet connection is your bottleneck. A test on www.SpeedTest.net will likely confirm this. However, if you get decent numbers on SpeedTest, then we could have something more sinister going on, though I suspect you'll find your numbers well below the 1 mbps rate. This brings us to actually changing the RAM. I've been out of the PC hardware realm (professional programmer now) for a few years, and was unable to find a manual for your particular model. However, if memory serves, this image should be a fairly accurate representation of the underside of your system: http://www.javin-inc.com/temp/thinkpad.JPG Don't quote me, but I BELIEVE the red circle will indicate the only screw you will need to remove to access the RAM. There should also be a small clip holding the RAM in place that you'll want to pinch to get the RAM out, and make sure that the new RAM snaps into place. (Sometimes you'll have additional empty RAM beds, and you can just put your RAM in there and end up with 1.5 gigs, but I suspect you'll have two 256 gig chips in there.) ---------------------------------------------------------------- 92033: Phew. Thanks again for your most indepth educational lesson. I appreciate all your help more than you realize. I attempted to answer this last night, typing in more than twice the amount of text as your to me, then suddenly realized there was a glitch and I was on another page...lost it all into the ionisphere. :-( Rather than try to retype all I wrote, I shut 'r down and went to sleep.

I'll ATTEMP to try again later. So please don't reply yet as you need to read my discoveries in changing the RAM chip. Meanwhile, thanks again...take care. ~ ED ******************************************************************************* TRY #3...I'm Back :-) Your diagram showing where the RAM chip is located was right on. Thanks. Here's my DISCOVERY :-( The RAM chip installed was NOT a 512mg...but only a 256mg chip. The ads ans specs say it's a 512mg...NOT SO. I was lied to by either the manufacturer or refurbishing company who removed the original 512 chip and reinstalled a 256 chip. I was lied to by the Tiger Direct guy on the phone. There are NOT two chip slots...only one. So I now have a useless removed 256mb RAM chip. Replaced with the 1gb RAM chip I just installed. So instead of having 1-1/2 gb RAM, I only have 1gb. Here's the crux. To. go to 2gb RAM I'd need to buy a full 2gb RAM CHIP and discard the 1gb for which I just paid $39.99 ($45.00 with s/h). This means another output of almost a hundred dollars plus the $45.00 just wasted because they wont accept return once the sealed chip plastic was opened...even though I had no idea there was only ONE SLOT in this PC instead of TWO like the Tiger Guy said. Now...crux #2...this new 1gb RAM does nothing more to increase speed. I just watched a 2.01 MINUTE YouTube video which took a HALF HOUR to load, so I threw the money away for nothing, eh? There is no noticeable change except the 'speed' shows it now as 41.2 kbps instead of 40 kbps. Okay...now HOW do I get to speed this thing up to normal viewing in real time? I also saw an ad for 4bg RAM Gateway laptop with 120gb hard drive for $404.99 which is all suped-up with everything. I had to upgrade a LOT since I got this only four months ago...taking over a hundred hours to load it, like Internet Explorer 5 to 6 and then to 8 and now to 9. I'm using AVAST Anti-Virus, after trying for 23 hours to get ADVAR, then find out it didn't load because of problem on the servor's end. Added Firefox and upgraded twice. Loaded MS Protection but it created more problems so I deleted it...now with AVAST which I like. Soooo...I've literally spent over 200 hours to get this thng where it's at now, plus the wasted money for the upgraded RAM chip.and I still don't have increased speed. HOW do I get it? IF the processor has to be changed does this mean I have to gut the thing and install a new motherboard? If so, what kind of money cost are we talking here? I bought this four months ago as a refurbished unit only because I was able to get it on payments of only $25.00 a month. If I had to wait to get $400.00 cash I'd never have it. :-) Okay...that's it for the moment. Thanks much again for your help offering and detailed instructions...appreciate it more than you realize. Best Wishes And God's Blessings To You And Yours In Everything Always. Most Respectfully... ~ ED  ---------------------------------------------------------------- Javin007: Well, let's start with the RAM. If you're running windows XP, you can assume all the extra processes (virus scanners, and whatnot) will be eating up about 512 megs of the RAM. First thing to do is check DXDIAG again (start/run) and verify that it's now reporting the correct amount of RAM. (Don't be surprised if it's like 9 hundred something megs or slightly more. It won't report 1024 or 1 gig.) This being said, that will leave you with the other 512 for your applications. This box won't be running the latest and greatest 3D games, but I suspect it was never intended to. If the heaviest hitter you'll have running is along the lines of photoshop, the 1 gig of RAM you have now should be plenty sufficient. I wouldn't worry about getting 2 gigs. Not for this rig, anyway. Also, Avast is a great (and free) virus protection, every bit as good as Symantec's Norton, so good choice there. If your youtube videos are choking out, we need to start by verifying that it's an actual speed throttling problem. Go to www.SpeedTest.net and run the speed test. Come back with the results.
