my mac book pro is refusing to stay asleep. I noticed it will wake up roughly every thirty minutes and display the screensaver password screen and even when the lid is closed I will be able to hear it wake and then go back to sleep quite regularly. I installed please sleep but that didn't fix it either. another curious thing I noticed was that sometimes when waking the mbp from sleep it will not let me type anything into the username/password fields. only closing the lid and reopening it after a few seconds will fix this.
I'm running 10.6.7 on a 17" 2.66ghz mbp i7 with 8gb ram.
my question is this: how do I find out which app is trying to constantly wake up my system? (wake for networks access is disabled.)
