Windows can do that and BIOS has such settings too. Those are
power management settings like "suspend to RAM after X minutes",
"hibernate after Y minutes". In order to hibernate it has to wake up
first, so there must be some place where a timer is set.
And I have seen it done on Linux. I just never tried it myself.
