As of several days ago, my MacBook refuses to go to sleep either automatically or manually. I have taken the following troubleshooting measures to no effect:
- Reset PRAM
- Rest SMC
- Boot in SafeMode
- Verified that the lid sensor was working (my MacBooks's status light responds when it's closed)
Anyone have any ideas would could be causing my MacBook's incompetence? I'm on 10.7.2 btw.
UPDATE: I found the solution to the problem: I had unnecessary sharing services enabled despite not using them for weeks. Turning these off fixed the problem :)
