This minHour teaches you how to make your PC or Mac computer start up at a specific time. If you're using a PC running any operating system (Windows or Linux), you can schedule automatic startups in the system BIOS. If you're using a Mac, you can set up automatic boot-ups in your System Preferences.
Using a PC
Reboot your PC into the BIOS.
The option to start your PC on a particular schedule is available in the BIOS, which you can access by pressing a specific key at boot time. This key is usually Del, F8, or F12, or F10. If you’re using a newer Windows 10 PC, try using these steps to enter the BIOS::

- Click Recovery.
- Click Restart Now under “Advanced Startup.”
- When the computer comes back up, click the Troubleshoot menu.
- Click Advanced Options
- Click UEFI Firmware Settings and click Restart.

Enter the time you want the PC to power on.
