About a year ago, my old iBook G3/900Mhz gave up the ghost. The video went out... not the monitor itself, but the video just quit coming up on the screen. The laptop itself still worked, but without video, it obviously hinders the usage of a normal laptop. Still, being the person I am, I couldn't bring myself to throw it away. "I'll get it fixed someday" I said as I put it away in the corner of a closet.
About a year later, we have Emmy, and Ginger wanted a laptop to use while holding her. My MacBook Pro 15" (the replacement for the iBook) is a bit unwieldy for her to move around while she has the kid. The metal case seems that it might knock the poor baby out if she bumped her head on it. My mind went back to the old iBook in the closet... should I finally get it fixed?
I did some searching on the net and came across iResq.com. $49 to have it picked up and shipped back, plus the price of repair. Hey, that's a good deal! I mean, it's an old laptop, it shouldn't cost too much to get it fixed... should it? I figure since I could buy one 'refurbished' online for about $250 that was an average figure for repairs. Since it's a laptop, I *knew* what I did to it over its life so I wasn't buying someone else's problems. I put in an order and off it went.
When the box arrived, I had to fill out a big question sheet. Where can we call you? What is your password? I filled it all in and put the box in the mailbox and waited. A few days later they called me. At home. I'm not home during the day since.. well I work. I put my daytime phone number on the paper you told me to fill out. Thanks for not looking at it. Time I got the message, they were closed. Okay, we'll call em the next day.
So I called the next day. 'If you're receiving this message, we're having an unusual call volume. Please leave your name/number, and we'll call you back shortly!'. 6 hours later I called them back.
"Yeah, we got your laptop - it'll cost $500 to fix. The logic board is out".
$500? The laptop is 5 years old. I'm sure you have piles of these lying around. I didn't say that, but it came out some like.. 'are you serious?'
"Yeah, these parts are hard to get"
Guess they didn't check Ebay. I told them no, please send it back.
"So you want us to ship it back?"
Here's where I think they get free stuff to fix other machines. You call them, they quote some high price, you tell them to just keep it... since it's broke = profit! Even if I parted it out, I could make about 200 bucks. So they sent it back... and I went to work on surfing the net looking for the fix.
Turns out that this machine was a pretty unreliable machine. Apple did a recall on them some years back but I didn't know it. What's wrong? Well the same thing that caused the Red Ring of Death on the Xbox 360. After some time, the video chip looses its connection with the motherboard - mostly due to a cold solder and some other factors. So really, it's not broke, it's just not connected. Common fixes include 'clamping' the chip back on with a big ol' C-Clamp and letting it run warm for a bit to warp it back into place. Others include putting pressure with an object on the top of the chip to have it make contact that way. Other ways are more fun - the pyro way is to light a fire on top of it to have the heat of the fire 'resolder' the chip to the board.
I did a combination of these methods.
First off, I opened up the laptop, scraped off the heat epoxy on the GPU and put a half dollar on it.

Notice the half dollar is a perfect size? My line of thinking is that half dollar will transfer the heat to the chip from the fire above it. Also, it keeps the fire from sitting right on other parts.

I took an old candleholder, put rubbing alcohol and lit it. It burned for about 10 minutes, but I wasn't sure if that was enough. So... I whipped out the cat's food dish which was tin.

... and did the same thing. It worried me a bit because the tin was almost resting on other chips.
I let it cool, reapplied the epoxy, and placed the half dollar right on it. I then added a piece of packing tape above it (double sided). Why? The laptop has a piece of tin that covers the entire circuit board and screws down. Once the half dollar was stuck to the epoxy, and the tape was stuck to the half dollar and the tin, and the whole thing was screwed down, it put pressure on the GPU. This should prevent it from lifting away from the board again.

So... did it work?
I put the whole thing together, and I'm currently posting this from the laptop. Total price? 50 cents obviously.
