How to automatically turn on the computer on Windows

Step 1: Restart the PC into the BIOS

A PC-specific boot option is available in the BIOS, which you can access by pressing a specific key when booting. This key is usually Del, F8or F12or F10. If you're using a newer Windows 10 PC, try the following to enter the BIOS:

1. Right-click on the Start menu and select Settings.
2. Click on Update & Security .
3. Click on Recovery.
4. Click Restart Now in Advanced Startup.
5. When the computer is back on, click the Troubleshoot menu .
6. Click on Advanced Options
7. Click on UEFI Firmware Settings and select Restart.

Step 2: Navigate to the option Power on Alarm or RTC Alarm 

The name of this menu varies by manufacturer and may be in the menu named Advanced.

Step 3: Choose how often to turn on the device on schedule

The steps to do this vary by PC, but you'll often use the arrow keys on your keyboard to highlight the day of the week you want your computer to boot at a certain time, then press the key to Turn on ( Enable ) or disable ( Disable ) for that day.

Depending on the BIOS, you may see wider options such as Every Day .

Step 4: Enter the time you want the PC to power on

You will often use the arrow keys to select an option called Time , although some BIOS settings require you to enter hours, minutes and seconds separately.

Step 5: Save the changes and exit the BIOS

Once you have exited the BIOS, the PC will reboot as usual and the changes will be saved.
