A possible fix for failure to sleep when inactive
Authored by: JohnnyMnemonic on Feb 14, '07 12:25:50PM

My MBP will sometimes fail to sleep on lid close; other times it works fine.

I find that the behavior will change on a reboot.

I haven't been able to narrow down the cause, however, and my stealth mode is already off.

I suspect that is has something to with power connection and lid-close timing, or how peripherals are disconnected.

A possible fix for failure to sleep when inactive

We recently came across this with a user on a 17" MBP. It turned out that Bluetooth was waking the machine up... even though it wasn't set to wake the computer in System Preferences. We disabled BlueTooth and the machine has been sleeping fine ever since.

A possible fix for failure to sleep when inactive

I have the same problem with the same experiences on reboot (had to do it today in fact). I really wish I had some idea how to fix it without a reboot (so time consuming). Another oddity I noticed today before the reboot was that exposé stopped working around the time I noticed that the sleep wasn't working. Don't know if there's a correlation or not ...
