The system cannot be shut down normally.

The specific method is as follows: "set/control panel/power options/Advanced Power Management ",

If the machine supports advanced power management, select "enable advanced power management support" and set powerdownaftershutdown to 1 in HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ CurrentVersion \ Winlogon;

If the machine does not support advanced power management, you 'd better go to the BIOS to check the power options .. I forgot the specific settings .. It is best to understand it yourself.

Why cannot a computer be completely shut down?
My computer is shut down by running the normal program in windows. It shows no exception on the monitor, and the display is shut down normally. But the host is irrelevant (the fan is still switching ). At this time, the machine cannot start again. It can be started only when the power supply is turned off first.

Why? This is a normal phenomenon !~~

Where can I turn on advanced power management?

XP system? Oh, desktop, properties-Screen Protection-power supply, advanced power management. If no, select S1 or S3.

Go to CMOS settings -- peripheral device parameter settings (Integrated peripherals) -- pweonafter PWR-fail -- off --

The system remains shut down after the power supply is restored.

On -- the system resumes operation after the power supply is switched on. It is best not to choose this option, because if the power is powered on again after the power failure, the system will automatically start.
Formersts-regardless of the status of the system before power is cut off, the system will be restored to the original status after power is turned on.
