I just started having this issue where when i close my powerbook lid to put it to sleep, it'll fall asleep (but takes longer than usual) and then 5 seconds after it falls asleep it'll wake up. and then i'll open it and sometimes it'll continue to be awake, but sometimes it'll go back to sleep... I've reset the PMU and the nvram. i've also created a test user account and i have the same issue there so it seems like it's a hardware issue... which really sucks. does anyone have any suggestions? it seems like whatever makes the powerbook realize it's closed is broken. hopefully that's a part that's easy to replace? I'm running the latest version of tiger on my 1.67 ghz low res powerbook g4.
