Help needed: Automatically turn on and turn off computer

[dvcd]

I can make the computer automatically turn on by setting BIOS. The password for the windows administrator has to be blank for automatically log into windows. If I set any password other than balnk, it will be waiting for the password there and will not be able to log into windows automatically.

I can make the computer automatically turn off by setting shutdown.exe in windows scheduler. But it works only when the administrator's password is NOT blank.

Does anyone know a solution to automatically turn on and turn off computer?

[reboot]

Get TweakUI for XP.
Set your password.
Set up scheduler.
Set tweakui to log on automatically.
