Set your computer to turn on and off on a schedule

This guide shows you how to automate your computer's power cycle, saving energy and time. Whether you need your PC ready in the morning or want a late-night movie session without leaving your machine running all night, scheduled on/off times are a handy feature.

Automating Windows PC Power On

Scheduling a Windows PC startup involves accessing the BIOS or UEFI (usually via F2, F8, Delete, or Esc during boot). The exact method varies by manufacturer, but look for an "Advanced Settings" or "Power Management" menu. Locate the "Auto Power On" option (or similar) to set your desired time. Our test Dell desktop used F2 and found this setting under the "Power" menu.

Alternative BIOS/UEFI Access (Windows 11):

For Windows 11, you can access the BIOS/UEFI through the Settings app (System > Recovery > Advanced startup > Restart now) or the Windows Terminal (command: shutdown /r /o /f /t 00). Remember to save your work before proceeding.

Scheduling Windows Shutdowns (Windows 10/11):

Scheduling shutdowns is simpler. Use the Task Scheduler (accessible via the Start menu or search bar). Create a Basic Task, specifying the days and times, and set the action to launch shutdown.exe.

Automating Mac Power On/Off

macOS Ventura requires using the Terminal app. The pmset command is used, with date (MM/DD/YY), time (HH:MM:SS), and day abbreviations (M, T, W, R, F, S, U). Examples:

• Startup: sudo pmset repeat poweron MTWRF 08:59:00 (weekday startup)
• Shutdown: sudo pmset repeat shutdown F 17:00:00 (Friday shutdown)
• Restart: sudo pmset repeat restart MWFU 03:00:00 (Monday, Wednesday, Friday, Sunday restart)

Older macOS Versions:

Older macOS versions offer a simpler method. Access System Preferences > Energy Saver (desktop) or Battery (laptop) and use the "Schedule" tab to set startup and shutdown times. Note limitations: one schedule per day, MacBook startup requires being plugged in, and scheduled shutdowns require an active login. Scheduled shutdowns might be interrupted by unsaved work.
