How to shut down computer by key board command,without using mouse?

windows doesn't have a command that I know of but apples is the 3 keys next to the space bar or command+alt+control and the escape key. That will shut your computer down.

Ctrl + Alt + Del

Then press tab until you get to the power down option.

Idk if that's the exact command you were looking for but that's one way to do it without a mouse

Make sure all windows are closed. Then press "Alt + f4". Your shut down screen should show up. Use your arrow keys to navigate to the shutdown button.

Alt + F4 then select shutdown with arrow keys, and hit enter.

You can use alt+f4 repeatedly to close each window, then the last alt+f4 will show the shut-down options.

1 - Press Windows key

2 - Press Right Arrow Key

3 - Hit Enter.

In CMD

Shutdown/s shuts it down, but shutdown/p shuts your computer straight away with no pesky warnings.

Alternatively, unplug it/take the battery out. :)

•CTRL+ESC: Opens the Start menu (use the ARROW keys to select an item)

shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]

[-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]
