What's the shortcut key to shutdown a laptop on the keyboard?

Welcome to Blackview (Retailer and wholesaler of work & play tablet, smartphone, and mini PC & laptop, etc.) blog. Hope this guide has been help.

The shortcut key to shut down a laptop varies depending on the operating system you're using. Here's a general guide:

For Windows:

General ways for most Windows OS, such as Windows 10 and Windows 11.

• Alt + F4: This closes the current application, but if you press it from the desktop with no apps open, a shutdown menu appears. You can select "Shut down" and hit Enter.
• Ctrl + Alt + Del: Press this combination, then use the power icon in the bottom-right corner to shut down.
• Win + X, then U, and U again: This brings up the power user menu, followed by selecting "Shut down."

For macOS:

• Control + Option + Command + Power: This will force a shutdown on most Macs.
• Control + Command + Eject (or Power): If your Mac has an Eject key, this will shut down the system immediately.

For Linux (varies by distribution):

• Ctrl + Alt + Del: In many Linux distributions, this brings up the shutdown or restart menu.
• Alt + SysRq + O: For some Linux systems, this is a lower-level shortcut for shutting down.

Always save your work before using any shutdown shortcut to avoid losing data.
