Question

Computers

Hello. Don't look at the tags.
Question. Is it possible to wake up the computer (wake it from sleep) at a certain time? That the computer woke up by itself.

Answer 1

Yes

Answer 2

The BIOS has a whole section for this with all sorts of Wake-Up methods.
There you can by the clock, both by keyboard / mouse and from turning on the network (it helps a lot when you need to boot the computer automatically when the light is turned off and then turned back on) and from the expansion bus (this is how they wake up the entire computer through a network card based on "magic packet" that came from the network)
