Possible causes of a self-waking Mac
Authored by: pub3abn on Jul 31, '07 08:37:04AM

I've had the same trouble with my PowerBook. But it occurs only rarely, maybe a couple times a month. I don't have a USB hub plugged in, just a USB mouse, ethernet, and phone line. I wonder if power flickers in the phone line could do it?

Very sometimes the ethernet can be a cause of it actually, try it without the ethernet plugged in?

Possible causes of a self-waking Mac

If you're using a PowerBook/iBook/MacBook(Pro), the easiest way to stop this happening is to simply unplug your power lead.

Oddly, the USB-device-waking-up-your-Mac 'feature' only occurs when running on mains power.

I use a USB KVM switch for my MBP and another computer and used to get frustrated by the switch waking the Mac for no reason...

Very interesting that Macs supply power to the USB hub even when switched off! I didn't know that, but I could easily make use of it!
