12-inch PB won't sleep

Message #1 - Posted 2003/09/30 - Jonas Simpson

Hi,

I've got a three-week-old 12-inch Powerbook G4 and it's not behaving as I'd like. When I close the lid, either on AC or running on the battery, the system continues to run and doesn't go to sleep. This happens with or without USB, ethernet, firewire or external VGA connections in use. With absolutely nothing plugged in and running on batteries, it refuses to go to sleep. I can manually put it to sleep from the Apple menu, but it should sleep on its own.

Has anyone experienced this problem and is there a known solution?

Thx,

JS

Try resetting the PMU?

The first thing is to find out where the problem lies. It could be a system problem or it could be a problem with your account. To troubleshoot those kind of problems, I created a "dummy" account on my PowerBook. When something doesn't work right, I logout then login in the dummy account. Then I verify if the problem persists. If it does, then it may be a permissions problem. I then try to repair the permissions with Disk Utility, or boot from the OS X system install CD and try to repair the system partition.

If the problem doesn't happen when logged in the dummy account, then I know something is wrong in my own account. In that case, what I usually do is rename my "Library" folder, logout then log back in. I then test for the problem. Every time I did that, I would always fix the problem. The hardest thing then is to find out what it is in "Library" that causes the problem. Most of the time, it's a preference file that gets corrupted in the Preferences folder.

My 1 day old 12" PB has this problem, also. But I think it has to do with the latch when I close the lid. The latch engages, but something is not right, as I have to push down on the lid a couple of times before the PB goes to sleep. Have you tried pushing down on the lid a bit after you close it?
