Re: Can cron cause computer to wake up from hibernate?

Hibernation does involve swapping everything in memory to disk, freezing the state of all processes, and powering down the system. But, the system being powered down does not mean that no part of the system is receiving power. In fact, Wake On LAN technology is designed to work on machines that are completely shut down - the only caveat is that the motherboard reserves power for the network card, and the network card scans for a particular magic packet addressed to it. If that packet shows up, the computer turns itself back on.
This would be the first time that I've ever heard of this. Forgive me for saying but do you have a reference?
So, not only can this bring a computer out of sleep or hibernation, it can bring a computer out of a shutdown, too, as long as the device is still plugged in.
Exactly! How would it bring my dead computer out or hibernation when it's in a moving truck? Methinks you're still thinking of sleep mode, not hibernation.

It's not the pace of life that concerns me, it's the sudden stop at the end.
