If you know, tell me how to set up the computer to automatically hang up.

To set automatic shutdown, you can actually do it only from the system's own functions, which is to enter the shutdown command in the run box. Open the Start menu and click Run. If it is not running, just press the keyboard shortcut to open it, win+r.

For example, if we want the computer to shut down after three hours, open the start menu, open the run box, enter shutdown -s -t 10800 in the run box and then confirm That's it. The 10800 here is the number of seconds in three hours, because the system memory shutdown time is calculated in seconds.

After clicking OK, a short black command box will appear, then disappear, and then a message will be displayed in the desktop tray, that is, the shutdown message. How many minutes will it take? closure. Then this prompt box will disappear.

If you regret it midway, or it is almost time to shut down, but you still have important work to do, open the run again and enter shutdown during the run. -a such a command and click OK.
