How to Automatically Turn On a Computer at a Specified Time

This teaches you how to set your Windows PC or Mac computer to start itself at a specific time. You cannot set a completely powered-down Windows computer to turn on at a scheduled time, nor can you schedule a Windows PC computer to automatically turn on.

    Click OK, then enter your Administrator password. This is the password you use to sign into your email account that's associated with the computer, but not necessarily the same password you use to log into the computer.

    • If you don't have access to this password, you won't be able to set up this task.
