i noticed the following problem with my MBP 8,1 running 10.7.2 — automatic sleep just doesn’t happen. Since I usually put my Macbook to sleep manually before leaving the desk etc. I just noticed this issue and can’t really pinpoint it to specific updates.
What happens automatically is display sleep. Computer sleep just doesn’t occur.
Closing the lid works, selecting “sleep” from the Apple menu works. The only way to put my MBP to sleep automatically is currently PleaseSleep, which works fine.
Here’s pmset -g:
pmset -g Active Profiles: Battery Power 1 AC Power -1* Currently in use: standbydelay 4200 standby 0 womp 1 halfdim 1 panicrestart 157680000 hibernatefile /var/vm/sleepimage sms 1 networkoversleep 0 disksleep 10 sleep 10 hibernatemode 3 ttyskeepawake 1 displaysleep 3 acwake 0 lidwake 1
As you can see, no process is preventing sleep.
Here’s pmset -g assertions:

Any ideas? I tried resetting the SMC, to no avail.
Bluetooth is off, Sharing is off. Automatic sleep doesn’t occur both on power adapter and battery power. Unplugging USB hub with things like keyboard/mouse connected makes no difference.
Thanks in advance!
EDIT Just booted into safe mode, and automatic sleep definitely works then.
EDIT 2 After removing Google Software Update, automatic sleep miraculously started working again.
