XP power management issues [Copy link]

There is no "Enable Advanced Power Management" item in my mind. What is the reason and how to solve it?
Before I came here to ask questions, I tried the following methods but they didn't work:
1. In the BIOS, go to Energy Management, turn on ACPI, and set it to S3.
2. Control Panel - Power Options, enable hibernation or advanced power management.
3. Modify the registry: Open the Registry Editor (Start → Run → Enter Regedit), find the "HKEY_LoCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" branch, find or create a REG_SZ type registry key in the right pane, named "PowerdownAfterShoutdown", double-click it and set its value to 0 (0 is to allow the automatic power off function, 1 is not to allow the automatic power off function)

In the power management setup in the BIOS, there are the following settings:
ACPI Suspend Type
Soft-off by PWR-BTTN
PME Event Wake Up
Power On by Ring
Resume by Alarm
Power on by mouse
Power on by Keyboard
KB Power ON password
AC Back Function
