Can anyone with technical know-how on Unibody MBPs help me explain my sleep problem? Just possible causes for it would make me feel a lot better. Its just bugging me that I don't know what the hell it is! Basically the first problem I had was that whenever I would close the lid, the MBP would sleep for a few seconds then wake up again. Then it would sleep again for a few seconds, then wake up again etc, etc. Also, if I shut it down and closed the lid, it would turn back on. To work around it, I'd have to click shut down/sleep in the menu then close the lid before it turns off. If I did that, it would shut down/sleep just fine. I didn't have time to bring it to my local service center again so I decided to try and remedy it myself. I reset the PRAM and the SMC but that only provided short term happiness. It slept/shut down properly for a few minutes, but after a few rounds of on/off or sleep/wake testing, the problem came back again. Then I decided to wipe my hard drive and do a clean install of 10.6. I went ahead and installed 10.6 retail on my computer. I then reset the PRAM and SMC again just to be sure. The problem then changed completely - it wouldn't sleep at all if I closed the lid. It doesn't turn back on anymore when the lid is closed though. I'm seriously stumped at this moment. Ideas, anyone?
