Thinkpad Question

Hey guys, I just re-installed my thinkpad r51, and I've been having all sorts of problems installing the drivers. I have a video driver finally from windows update but the actual driver package I got of the site for it still doesn't want to install. My wireless won't install either. Lenovo offers 3 different drivers for my particular model and I've tried all three, the first two said they were installing it, but nothing happened, third one installed and it worked as far as the installation but for whatever reason it got very very very slow like there was some dead device holding my computer up. As soon as I uninstalled it, it was fine again, and no I could not manage to even try the wifi because it was so slow, got the window open a few times but it crashed. I have no bloody idea! I've already reinstalled this machine and everything was fine, and all the driver packages installed not a problem. I definatly need the driver for my wireless and the video driver will be helpful so I can control the outputs (seeing as it's a laptop with 3 diff video outputS)

Thinkpad ideas, please.

I seem to have acquired an elderly IBM Thinkpad.  It appears to be fully functional, but... It's running Windows 98, It has a single USB socket, but does not recognise any of the pendrives I plug into it. It has a floppy drive that can be plugged in the side It has no wifi. I have never done anything constructive inside the guts of a computer. So, basically, it's useless to the modern laptop user.  Raw materials. Any ideas?

Thinkpad t42 malfunction

I have an old IBM Thinkpad T42 it worked fine for several years. but recently it started malfunctioning. Whenever i shake it the screen goes black and the laptop freezes. If I take out the battery and put it back again it starts up every time. I disassembled it and checked everything but i coudn't find the cause of the malfunction. I think something toutches the metal frame but i coudn't find what does it. Can someone give me any idea what's the problem is?

I need some expert mac help!!

Okay, I got a bit of a story, and a bit of a question (Las Vegas, I know you can help me). I've been transfered to a new highschool (not that new to me, I've been to it before) and I've been there for about 3 weeks now. I was given a thinkpad R51 by the school board while I was out of school to use for school work and to take to school. That's all fine and dandy, but the restrictions on their disc image are unbelievable and it makes it next to useless to me other than a gigantic calculator with a shitty battery life. So I wiped it of course, repartitioned it with a 30 and 10 gig partition (respectivly both NTFS, the backup partition, the 10 gig one, is currently in fat32 as I forgot macs can't write to NTFS). So everything works fine, when I got transfered to the school, I asked the so-called "head" techy teacher person of my school for the wep key for the wireless network in my school so I can print my work out in class instead of waiting till I got home (teachers don't like that sometimes). Since I've been to school he's made up excuses like "I know I have the wep key wrote down somewhere, but I know it'll take me like an hour to find it so I can't right now - I've been told that on 4 different occasions on 4 different days. Funny thing is that both he and I know that their wireless isn't actually pure wep mode. It's a wpa enterprise mode of some sort with a required username/password combination to log into it (that's fine though, it'll still work if I have the password). Oh yeah I forgot how I took my ibook to school one day, then the next day (no not the day I was showing him my ibook) he tells me that the wireless will work on my ibook, but not the thinkpad, which, like every other fucking laptop in the school, is a model R51 type 1829 with the odd old R40 laying around. It's excuses after excuses, my mother wanted to call in and give them hell for leading me around but I told her no, I'm curious to see how dumb this teacher thinks I am (and so far I've been playing dumb). NOW he tells me that I need to now, re-image my thinkpad with their school disc image they use on their machines, which I don't have to agree to doing because the laptop didn't come from this school and so it's not theirs. There was absolutely no reason it would not work as I even used the exact same wifi drivers/software and even the same profile management software they use on theirs. Now, I'm almost done but let me explain the last bit of why I'm even posting this lenghty (and possibly waste of time) post. I recently re-reformated as somehow I contracted a nasty trojan downloader onto it, and it was due for a clean up anyways. Well wasn't that a rough ride, since the reinstall I've had to wrestle a video driver onto it, fiddle around with all the other drivers to get them installed, and I still can't get a wifi driver to install. Even if I force install one from the "manual" option when XP asks for drivers (yes XP does have generic Intel Wifi lan drivers for my card) and it wouldn't go, just gave me an error 10 code (device cannot startup). Okay, so the driver isn't compatible? Well Lenovo only has 3 different wifi driver packages for different wifi internal cards for my "one" model/type of laptop (the type "1829" is lenovo's numbering system basically for revisions, and when I went on their site for drivers, it askes me for this, model, and a specific 3 digit number on the bottom (order code I think). So why it can't just tell me the specific card in my revision (as I'm sure there's probably only one card for my revision) is beyond me. I downloaded all three, the first two were just small driver/utility packages (I think they were only 802b drivers too, at least one of them was). When I tried to install them, no luck, first appeared to install it, although the drivers never installed apparently. So I uninstalled what (still) there, and tried the second, same thing, except nothing installed, but it appeared to install. So I went on to the last one, it appeared to be succesful. Not, for some reason, windows could list me all the ap's around here, but couldn't connect to them, or mine, and I know I put the right key in. And when I tried to use Ibm's utilites to connect, it kept crashing, and it was even crashing the wireless zero config windows service thing every time I tried to power on the wifi or such. However I don't even care about windows right now at this particular time or fixing the drivers, for all I know there was a scratch on the install cd and it's botched (very unlikely as I know the install would halt and say it can't read) Now because my teacher has been literally screwing around with me (I'm not assuming here that he's lying to me and making excuses, I know he is because it's just too obvious, you guys tell me). Plan? Install mac os x on the thinkpad and ask him again if it'll work and if he says no, I will probably rip him a new asshole right there on the spot, seeing as he's told me multiple times it will work on my mac, but not the thinkpad, so if I have mac software on there, shouldn't be a problem (hehe). I really want to do this to get back at my teacher because he doesn't believe anything I tell him and he thinks he's pretty smart, just generally another guy with a too-big ego for one person to handle. I downloaded the iAtkos disc image as directed by instructions I found through google (yes, torrent, illegal, don't harp on me for it, jobs makes enough as it is with ipod sales). It's supposed to be pre-patched, and also supposed to include additional driver packages of some kind (that's a plus). And to boot, it's supposed to boot off the dvd (lawl) without any tricks (like usb drives and that smutz). It all seems pretty sweet, and it did boot when I popped it in, but It went to the mac loading screen (the white one with the grey spiny thing) and just sits there with absolutely no activity. I booted it with the -v/-s command(s) and this is what comes up when it stops loading and sits: "Extension "com.apple.driver.ACPI_SMC_PlatformPlugin" has immediate dependencies on both com.apple.kernel and com.apple.kpi components; use only one style." My understanding is that the plist file might be missing some components the driver is calling for, but the "use only one style" part doesn't make sense so I know it's something else. Although it didn't say, I presume the kernal was already patched as it was supposed to be a pure pop-in-and-go image. I was hoping to try installing the EFI patch after too if I can get it going in the first place. And yes, I did quite a bit of googleing before I came to here. I could find information on R40's with mac os x installed on them (or was it x40?, I know those are newer, the r40's are old) and other models inbetween but nothing on thinkpad. I don't even care if it's fast or works 100%, I just want to do it, I do also know that the atheros chipset in my wifi card is native compatible with tiger apparently and should show up as a standard airport card. I don't know if I'll be amazed or not when I post this finally and see how many pages long it is, but I do really need a hand, because this will be the final step before I go to the VP and tell him that this guy has been screwing around with me and blowing me off. I deserve and education dammit!

How do I fix an IBM Thinkpad battery?

Hello. My family has this really old IBM Thinkpad that sits in my room nowadays. It runs Windows 98 Second Edition (SE). It's a pretty good little unit, but the battery won't hold a charge, and thus, only works when plugged in. Is there any way to fix this without having to buy a new battery?

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?

What os is right for me and my laptop? Answered

I'm going back to collage and at this point i feel stuck with my laptop. I currently have window 7 running on it since all the driver issues are not a problem, but the boot is incredibly slow, it was that way for xp too. I used linux on the laptop before but I had issues with my video card driver not working and not being able to nativly run office 2007 or somthing that can open docx and pptx files without problems. I'm also able to play mine craft on windows 7 but not on linux becouse of the video driver problem. In short, do I stick with linux because it's faster and lighter with less abilities or sick with slower windows that from time to time will freeze. Just to mention I have an thinkpad t42. (please no comments saying get a new laptop i can't afford it).

Broken backlight on laptop screen - Project ideas anyone?

I'm opening up to this lovely community since your creativity never fails to amaze me. I've had a laptop that has been sitting in my closet for about a year (Its a Thinkpad T43 i believe) which was in fair shape until one day it would no longer function, hence the closet bit. I got a little curious when I was digging through clothes and found it again, and played around on it and noticed if you held a light directly on it you could just barely see the screen, so I managed to reinstall windows, hook it up through S-video to my TV, and voila. But I dont use it that much, so I wanted to do some kind of project with it. I've seen the DIY projectors made form overheads, which would seem like a logical choice since it'd be easy enough with a working screen that has no backlight, but the thing is I already own a projector capable of 720p/1080i so I'm skipping this one.I've seen people do multi touch with screens before (ie things like http://multitouch.fieryferret.com/2008/04/finished-table.html) . but I'd want to do something larger. Then there's things like https://www.instructables.com/id/Back-projection-56-inch-multitouch-television./which are cool, but i dont have the need for something large in that format. I'd like to do something like a large coffee table with multitouch (like Surface) but I'm not sure how possible that is to do. Here's a rough sketchup of the basic idea (very basic, very rough. I'm at work wiht only access to MSPaint, and should be doing work anyway :) but with the 56 inch they have that mirror setup and I dont think you could do that with something that low to the ground (like a coffee table), correct?i'd love to hear your thoughts on that, but also.. what do you guys think? Got any good ideas for laptop with just the backlight blown? I dont really need a fileserver, and I have another laptop, so if you guys have any wild ideas out there.. I'm game.Cheers,Ian

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. Now I'm trying to recall all I wrote last night but failed to get mailed. I'm not a traditional typist, rather a one-finger bloke so you can understand the frustration there. I do, however, type at a reasonably good speed. With that said, let's continue. I went to search for Configuration of this IBM Laptop ThinkPad 23738TU and am copy and pasting it here.

IBM 23738TU Summary ********************************************************************************* NOTE...I DON'T BELIEVE THIS...I JUST TYPED FORTY MINUTES REPLY HERE and it instantly scrolled up like speed of lightning and disappeared like last night. 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.
