Possible causes of a self-waking Mac
Authored by: tbolioli on Jul 31, '07 08:01:19AM

The USB idea is very plausible because Apple keeps the USB hub fully powered in S3 (sleep), S4 (hybrid sleep) & S5 (off) so folks can charge their iPods off of the USB bus while the machine is down. Any supply side issue to the power would likely cause the USB bus to be the first to suffer and likely cycle into and out of the USB low power state as a means of self preservation. That would cause the various attached peripherals to respond in kind fooling the system into thinking that input from the peripherals was received. Just a guess though based on what the submitter wrote.

Possible causes of a self-waking Mac
Authored by: morespace54 on Jul 31, '07 11:01:19AM

For whatever that's worth, I have a USB LaCie Drive which keep my computer from sleeping :(

At least, as long as I don't
a) eject the drive,
b) turn the drive off (or hot swapping it) or
c) shuting down my computer!

But that's because my drive doesn't automatically go to sleep.. Dargn LaCie!
