[QUOTE="BeyondTheBox, post: 1141358, member: 179315"] I was extremely surprised when I joined this site to find that there was absolutely no information whatsoever on the old narcoleptic problems of the PowerBook G4s. Granted this product is rather outdated, thus any topics surrounding could easily be archived, but I performed the due diligence using the search function so I'm hoping there'll be some sort of help here. I'm trying to find some avenues I can take to eliminate some of the problems, as I've heard it can be a few different things: I've already replaced the power converter/inverter. Immediately upon installation the screen flickered before it came up, just like it did when the old one went out, but then it worked flawlessly for about two weeks. Enter elimination 1. I've spoken to numerous Mac repair shops, all of which say that it's either that piece or the logic board, however everything I've read online says that's what they say in order to do it and charge you a buttload. The real problem, if power converter doesn't work, is that one of three sensors has gone out. The most likely culprit being the right side light sensor, just above the speaker, which tells the screen to sleep, has malfunctioned. The other two are, of course, the left side light sensor, or the trackpad heat sensor. My understanding is that if it's either light sensor it can simply be bypassed by clipping the wires to them or replacing. If it's the trackpad heat sensor causing the screen to permanently sleep, it creates a log that tells the display it needs to sleep and to test the case you can simply create a new user account on the computer, which would create a whole new set of logs, and under this user the problem shouldn't exist. What I want to know is, can anyone confirm my thoughts here, or do you have something useful you can add or subtract from the equation. I think the first thing I'll do is try a new user account, though it's hard to do on a sleeping screen. Next I'll try cutting out the right side light sensor. If all else fails I'll feel like a real buffoon because I'll just wind up taking it right back to one of the shops that told me the logic board needed replacing. Thanks in advance to anybody who took the time to read and be of any help here, I know I can be quite long winded, but I like to be detailed and thorough. [/QUOTE]
