Some of you may remember me complaining about flaky behaviour on my ti 550 over the last few months which manifested itself as the infamous "Wake from Sleep" bug as well as random hangs.

I drove myself crazy trying to fix this using all kinds of voodoo but nothing seemed to work. Last week, however, I discovered what the problem really was and, since it looks like a hardware flaw that might affect all G4 PB users and it's easy to fix if you know what to look for, I highly recommend that you have a look to make sure that you are not going to get this problem as well.

Bascially what I discovered was that a couple of frame screws (located under the keyboard) had loosened and that a small ribbon cable (located just under the left side of the space bar) had slid under the frame and was getting abraded (through normal use of the keyboard). It had got to the point that whenever I pressed on the Cmd key, I would get a short and the computer would hang. For some reason this also made sleep with the computer a very risky proposition (I basically had to give up using it b/c the computer would hang 100% of the time on waking).

The image below shows the cable after I dug it out from under the frame and tightened the screw:



I figure that the cable must have been under there for months getting gradually worn down to the point that there was a breakdown of the insulating plastic. I suspect that there might be more unwitting PB owners out there with this little time bomb ticking away under their KBs.

Since fixing it I have had absolutely no problems. It's like my machine it brand new, I can use sleep without any worries at all. If you look close you'll see I put a tiny piece of clear tape over the cable to protect it, crude but it works.

Check out your machines!

If you've got a Ti, have a look under the hood, it might save you _a lot_ of aggravation.

I just checked the underside of my TiBook and found that I'm missing a screw. Not only that we have to keep up with all the software updates, we must now check the hardware and keep them from coming apart.

Well I've only had the chance to inspect one other Ti (jwoodget's Ti 667) and we found exactly the same thing (loose screw and with the orange cable tucked underneath the frame).

I'm telling you people, have a look, you might save yourself a big headache.

Thumbs up

Thanks for the heads up. My wiring and screws are okay for now but I'll make sure to keep an eye on what's going on underneath. [img]smile.gif[/img]
