I have a desktop system at work with debian squeeze installed. Every couple days or so, when I come in in the morning, the system appears to be asleep and won't wake up. I suspect it goes into power save mode and then doesn't receive the wake up signal when I click the mouse or touch the keyboard.

Does anyone know where I should look in order to start tracking this down? Like log files, etc?

I doubt it, but maybe the fact that I'm using a mac aluminum usb keyboard and a wireless usb mouse (that has an off switch) has something to do with it? Maybe, when I turn my mouse off at the end of the day, the system loses track of the device somehow? I dunno :P.

Thanks in advance.
