wake-up by the computer

Question

some time ago(10 years back) I've read on PC Magazine that some mainboards have some settings which allow to a computer to open at a certain hour. I need to make my computer to wake me up in each morning. How can I do that ? What MB settings allow this feature?

ps: i will like to shout down the computer during the night(not sleep or hibernate mode). ATM I'm using windows xp and 7 on my computers.

+1. Looking into this myself, as I need to start powering down my PC at night. It is drawing too much power. I will answer if I find a working result. — Myersguy, May 26 '10 at 07:55
Do you want the PC to start at a certain time in the morning, or to use the PC as an alarm clock (to wake you up), or both? — sblair, May 26 '10 at 08:18

Add to the comment of jjj a pretty obnoxious Windows-start music, and the deed is done. — harrymc, May 26 '10 at 08:44

Most BIOS have an option to wake the computer up at a defined time. This option is usually named "Resume by alarm" or "Wake-up on RTC", something like this (not wake on lan, though, this is something else).

You can find more details about it at this article.

Nb: You can find a list of keys to enter the BIOS setup at this page. It should however be written in a corner when booting the computer.
