How do I automatically Turn on/off my computer at certain times and dates? It is not in the BIOS settings. I was wondering if there was wondering if there was any tricks or special software I can use.

Turning off is easy, just use the Scheduler to do a shutdown /s at a specified time.

Unless BIOS supports it, there is no way to turn a computer on once it's powered off.

go to run type
shutdown -s -t 3600
(for 1 hrs.)
86400
(for 1 day 3600X24)

to cancel this
type shutdown -a

You can schedule your computer to "Wake up" at a specific time - but note that it has to be coming from a sleep or hibernation state, not powered down. If you turn off your computer, no software or scheduling program can run.

If you have a second computer on your network, you can configure the first computer to use the "Wake on LAN" feature found in most BIOS Setup Menus, then have the second send a network command to wake the first.

Another option is to plug the PSU into a timer, then configure the BIOS Setup Menu to boot when power is restored. However, I would not recommend this because of the risk the timer may suddenly shut off the power causing the computer to hard crash - never good.

That said, your computer(s) should always require a password to boot into the OS/user account - even if you are the only user of that computer. This is to make a bit harder on badguys should your computer be stolen, and to keep others ("friends") from snooping around if you are not present when it starts. So this means if you want your computer to boot up at scheduled times when you are not present, you must remove any passwords and that is a big security risk, and not recommended.
