With the bottom plate off, but not the heat shield, I attempted to start the computer to see if the repair had worked. I saw a spark shoot from the aluminum frame to the heat shield. Now the AC adapter no longer glows and the computer isn't responding. What have I done and can it be fixed? Thanks to all in advance. I took my laptop apart today to attempt this.

It does this after about 5 minutes. Would this be the same chip? I have tried several times with a soldiering iron. Still happens... My 2004 ibook screen freezes but does not go blank.

Runs fine when just closed and reopened for use. But reboot is another issue. The case needs to be twisted/flexed to allow the PS to work properly, or I get full fan, no displ. Must flex during initial boot call of pwr sw or within 1sec to work. Getting harder to accomplish. Looking into the cold solder joint of the chip. Lest you have another experience.

Should have written so when I did a repair thanks to it, but I let this slip... Similar syndrome came up on a local Apple forum ( Intermactivity.be), So I looked the bookmark over before posting a link. Pity you do not write in Dutch as well! As to the fix: with my machine the issue came back, so I have to perform the same trick. I only resoldered 2 pins at the time & with ROHs compliant solder, so either I performed poorly or the stresspoint on those pins is a very severe one. Moreover I do not dare to apply better fluxing PbSn solder to what seems to be a ROHs compliant motherboard, although I hear & read opposing comments on this. Once broadcasted on the forum, I"ll keep you posted if more of these cases are (still) being overhauled thanks to your instructions! I think I already have at least 3 cases tracked down already.

My old iBook G4 has been on a side of my desk for 8 months. This morning I decided to fix it up and I found this guide. Now, by pressing the back in the middle, it starts up again! I need some tools and all it'll be fine ... I guess. Thank you!!! My old iBook G4 has been on a side of my desk for 8 months. This morning I decided to fix it up and I found this guide.

I inserted the system restore/os cd and then it started working again. On removal of the CD it now turns on (and off) and boots-up as normal. Good news. What just happened?? Cheers.

It was a freebie but still a shame. Now: the startup sound plays, the Apple screen displays but remains on the mini-spinning spoke-wheel anim as if it can't find...something. The hard drive? Any clues? Cheers. I think I killed it… It was a freebie but still a shame.
