- Unplugged the power adapter
- Selected Sleep from the Apple menu
It would not sleep when I shut the lid or selected Sleep with the adapter plugged in.
As it turns out, not sleeping is common among MBPs running 10.7. There appear to be a number of causes talked about on this Apple Support thread, but user jcarpio had the fix for my version of the problem.
In Terminal invoke the power manager settings utility:
start ) pmset -g
This is the output:
Active Profiles: Battery Power -1 AC Power -1* Currently in use: womp 1 halfdim 1 sms 1 panicrestart 15 gpuswitch 2 hibernatefile /var/vm/sleepimage networkoversleep 0 disksleep 10 sleep 0 (imposed by 70, 30977) hibernatemode 3 ttyskeepawake 1 displaysleep 10 acwake 0 lidwake 1
The entry for sleep shows that 2 processes are preventing it: 70 and 30977. To find the owners excute:
start ) ps -ef | grep 70 0 70 1 0 6Nov11 ?? 0:01.26 /usr/libexec/InternetSharing start ) ps -ef | grep 30977 0 30977 1 0 11:06PM ?? 0:26.89 /System/Library/CoreServices/backupd
I turned off Internet Sharing and stopped the current Time Machine Backup.
start ) pmset -g Active Profiles: Battery Power -1 AC Power -1* Currently in use: womp 1 halfdim 1 sms 1 panicrestart 15 gpuswitch 2 hibernatefile /var/vm/sleepimage networkoversleep 0 disksleep 10 sleep 0 hibernatemode 3 ttyskeepawake 1 displaysleep 10 acwake 0 lidwake 1
Notice that "(imposed by ...)" is now gone. Now the laptop sleeps when I close the lid again. No more smoking hot laptop!
