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.

   Open the Start menu. To do so, either click the Windows logo in the bottom-left corner of the screen, or press ⊞ Win.

    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.
20.

    Click OK. Doing so will save your task and apply it to your specified time. Keep in mind that your computer must be sleeping--not powered off entirely--for the task to wake it
