Laptop constantly goes into sleep mode
Hi! I've got a 12" 1.33GHZ G4 which boots up fine, but then constantly goes into sleep mode. You can wake it up, but within seconds it goes back to sleep. Occasionally it works longer, but without fail it ends up asleep again, and it is therefore unusable. Thinking it was a reed switch issue, I replaced the entire screen assembly/cabling twice with known good units, and both times it had the same result. I've also reset the PRAM and PMU, removed the RAM and battery, tried a different topcase, etc. This model does not have a magnet on the right side by the optical drive, so it's not that. It seems to be something with the board. Anyone have ideas? Thanks!
Is this a good question?
