Windows 8.1 will automatically shut down when idle, it is really unattended

My friend's Windows 8.1 system has a small problem, and his computer shuts down when it is idle. This situation may be related to the improper setting of the power supply option, but it is still necessary to analyze the cause of the problem. Let's take a look. Before his computer, everything was normal. After pressing the power button a few days ago, due to temporary problems, I did not wait for the password to enter the Microsoft account interface. After about 40 minutes, the display frequency is black, but the power button is at the boot button. The light is bright, he pressed a lot of mouse, the display does not have any reaction is still a black screen, but can only press the power button again, this will restart (longer time). After the boot, a hidden file desktop appeared on the desktop. After deleting it, it was found that after 5 minutes of idleness, the display screen was black. After a black screen, press a few mouse clicks to enter the password to re-enter the Microsoft account. The light at the power button will not light up after 10 to 20 minutes, and it will automatically shut down. After rebooting, the previously deleted desktop file appeared again, and the computer will automatically shut down after about 20 minutes of idle time. If the computer is always operating, there is no problem, just after the computer is idle, it will automatically shut down after about 20 minutes.
