By sleep, I mean "stand by" in WinXP Pro. No fans, no disks sprinning.
Just a blinking power light. I haven't hung around after manually
putting it into stand by to see if OE wakes it up. Is that possible?

When I get home, the computer is still in stand by so I'd imagine OE
isn't functioning. Is that is true, I have no idea what else is
checking the email account and causing it to lock.

Thanks,
Brett
