My Laptop Is Broke. But how? Answered

I have an old dinosaur laptop (a Fujitsu Life-book C2330 approx. 7 years old.) that worked up until very recently. I packed it up in my closet for a few weeks, and when I decided to re-purpose it, the laptop wouldn't power up. I believe the problem is not in the laptop itself, but in its power transformer. When the transformer was working, it would make a high-pitch, low volume, whine. But now the transformer only whines once for a half second every five seconds. This could maybe be attributed to a blown capacitor or other electronic mishap. If that is the case however, it would probably be more worth my time buying a new transformer. My second idea is that the transformer has been damaged but usable for a while, but the laptop requires a slight charge of some kind in the battery to get it going, and the old transformer doesn't have the guts to give that charge. Metaphorically leaving me with a car with a dead battery, trying to jump-start off another car with another dead battery. If this is the case, then I should buy a new battery. My third idea is that both the transformer and the battery are not the problem, and it is the power jack that is the problem. I had to open the computer up not too long ago to re-solder the loose power jack. The screws that attached a ridiculously large EMI cage to the motherboard were stripped, so I had to drill them out, and then bend the EMI cage about 45 degrees. That allowed me to fix the power cord, but it also damaged my internal wireless card. After putting it all back in one piece, the laptop worked fine until I bought a new one, when I put it in my closet and forgot about it. Which brings me back to the thought that the power jack is broken. But it doesn't look broken at all, it doesn't feel broken, and it doesn't jiggle in the laptop. And if the jack is broken, I might as well just give up. The last possibility, is that the laptop, the transformer, the battery, and the power jack are all usable, but the power cord, which looks fine on the outside, might have lost its conductivity, or become frayed and detached inside its rubber casing. Which can be easily fixed by opening it up and reattaching the wires. That's my situation. I don't know which of these ideas it is, but it has to be one of them. I appreciate any help I can get. Sorry for the bad image quality. Not that the pictures help much anyway. Thanks, Sam

iPod crash question? Answered

Roger-X's iPod Touch appears to have crashed. He was watching a programme via the BBC iPlayer app and turned the iPod over 180°. The picture started to rotate as expected, got to about 45°, then froze for about 30 seconds. After that, the screen switched to a pale-white glowing screen with no image or text. It is not responding to the home button or the main power button, plugging it into our PC gets no response (the PC does not register its existence, either) and, of course, the local Apple store closed 10 minutes before it broke. Any ideas for a fix, folks?

Flyback transformer broke in two days Answered

Hi, I made a flyback driver from a 555 timer 2 days ago and now its not working. I think the flyback broke but i dont know. I ran the driver with 6 volts at first but got tired of the 1 cm sparks so I used 12 volts instead and it stopped working. I left it alone for a while, and when i tested it again, it worked again. Now its not working again and i think the flyback broke this time but im not sure.

I broke a pin on a barrel jack

I think it is the ground pin. Looking at specs I found online http://www.cui.com/pdffiles/PJ-002A.pdf , the ground is connected to the (+) pin(?). It was the pin at the base, not the big center pin. Is my assumption correct? Thanks.

Only read this if you are a kind person. Thank you.

Thank you for taking time to read this post. I realize it is rather long. If you are not a patient person, you may wish to simply skip reading this.I live in Washington DC and am looking to purchase something very specific, preferably from a reputable online retailer. I am a simple person, without any formal education. I know nothing about electronics or engineering. I hope you can be patient with those facts. I have no tools, no skills, no money, no knowledge.I'm searching for something that has been surprisingly difficult to find. Please, if you haven't got anything constructive to comment about this post, would you please just not say anything? Life is already difficult enough without negative words or sarcasm. Perhaps you might know of other internet consumer bulletin boards/forums that might be better places to ask this question? There don't seem to be very many at all.I am well aware that most modern cell phones easily fill the requirements that I am about to describe. Unfortunately, this item is needed for elderly people who are very suspicious of and dislike all things new. They violently refuse to accept a cell phone.Even if perfect, it's going to be a battle to get them to try it or use what I am searching for.So. Here we go. Maybe I can't find ALL the features, but here is what I am hoping to find:This needs to be a digital timer that can be set to go off at a minimum of six different times in one twenty four hour period, regularly.It has to have both an audible alarm and a strong vibration, and it has to be switchable between these two. Even better if it also flashes or lights up when the alarm goes off, and that also has to be optional, switchable. Very good if the strength of the sound or vibration can be adjusted easily.Should have a belt clip, preferably made out of metal, not cheap plastic.Should have a place where a neck rope could be easily attached and detached.Should have buttons that can be locked, so that no accidental changes by accidental bumping will occur.Should be water resistant. I'm talking about it being able to take a splash from a sink, not something to withstand being taken in the shower.Should also function as a typical normal digital watch with calendar feature. should be SWITCHABLE between calendar and clock view, so that all letters and numbers are as LARGE as physically possible,not all crammed on one tiny screen.Display should be larger than a normal watch, but the overall device must be small enough that a senior would not be upset to wear it around the neck or put it in a pocket, such as a normal shirt pocket.Great if it includes a strong LED flashlight feature, something with an on/off button, NOT a button that you have to hold the button down every second that you want the light to beam.Display should either be always back lit or at least have a button that will make the display light up without having to hold that button down the entire time you want it back litGreat if it came with a DVD of instructions with video, not a flimsy booklet with tiny letters written by someone who can't correctly speak English.It must run on batteries that can be purchased at any national retail chain, such as WalMart or Target. Fine if it has a very long life rechargeable battery built in, but not so fine if that battery is welded in so that it deliberately cannot ever be replaced.Good if it is able to run on the type of rechargeable replaceable batteries such as Nickle Metal Hydride or one of the others, without damage to the device.If it MUST be a plug into the wall rechargeable type, the cable cannot be a tiny pain in backside USB cable, it should be very simple and EASY for someone with arthritis and bad eyesight to plug in, perhaps with a charging cradle dedicated for the purpose, which can just be left plugged in somewhere.The charging device should have bright clear LED lights showing both that the device is currently charging as it should be, and another light that will FLASH to indicate it is now fully charged.Should sell for a price that a person that worked a lower middle class life and now barely gets by on Social Security could afford to buy. This device is not for me, if that matters at all. It is for people I care about.

My kid broke his arm, is getting a cast tomorrow, should I try to add some LED's?

My 6 year old broke his arm on friday night, they can't do a fiberglass cast until tomorrow. I was thinking what if I prewired an ultra bright LED and ask them to wrap it into the cast with just the led poking out. I was thinking I could decorate his cast to look like Buzz Lightyear's arm with a "laser". The wire could come out the top that I could connect a battery pack to so he can turn it on and off. Is this a good idea or not too smart? I'm trying to think of ways to make my son feel a little better about having a cast for 8 weeks.

I broke an LED; will connecting the one wire leading in to the wire leading out break the device?

I have a broken LED. Will connecting the wire leading into the LED to the wire leading out of that one LED break the device? I don't have solder so my plan was to twist together the stripped wires and wrap in electrical tape. Would powering on the device cause any sparks? The LED is part of a group of LEDs in a ring around the cone of a hair dryer. There are wires leading up to this ring-shaped circuit board with six leads and a resistor. Would directly connecting the two wires leading up to this ring-shaped board break anything or potentially be hazardous if operating the hair dryer? Now that I think about it, the electrical tape would not be a good idea as it would probably melt pics: http://i.imgur.com/pSmSvUc.jpg http://i.imgur.com/X7GUoDn.jpg
