Hi,

I have just reinstalled windows XP Home Sp2 on my computer and now Windows will not shut down automatically when I try to turn off my computer it says that it is now safe to turn it off. This worked fine before I reinstalled Windows. Is it best to do another clean install of windows and see if that fixes it.

I would be grateful if someone could please advise me on how I can fix this problem.

Many Thanks,

This is usually cased by an ACPI incompatibility ... When XP is first installed it tries to determine what type of BIOS is available on the computer.

Newer systems have what is known as Advanced Configuration and Power Interface (ACPI) capability. Unfortunately, XP doesn't always recognize a computer BIOS is ACPI capable and doesn't install the support for ACPI.

Once you drop the CD in the tray and fire up the computer to install XP, one of the first things you should see at the bottom of the screen is the option to press F6, if you need to install a SCSI or RAID controller.

Don't press F6. Press F5 instead. This will take you to a separate menu of Hardware Abstraction Layer's where you can choose an appropriate HAL that supports ACPI.

The choices will/should be:

ACPI Multiprocessor PC
ACPI Uniprocessor PC
Advanced Configuration and Power Interface (ACPI) PC
Compaq SystemPro Multiprocessor or 100% Compatible PC
MPS Uniprocessor PC
MPS Multiprocessor PC
Standard PC
Standard PC with C-Step i486
Other

In the majority of installations the 'Advanced Configuration and Power Interface (ACPI) PC' HAL is the one you will want to use.

The only way to really fix this is to re-install XP.

Once XP is installed ... Right click My Computer then click Properties / Hardware / Device Manager.​

Expand the entry called Computer.


If the entry is 'Advanced Configuration and Power Interface (ACPI) PC' you're all set. If it says 'Standard PC' the computer BIOS was not detected as being ACPI capable.​

If your PC is NOT fully ACPI compliant, then look for a BIOS update


What was the reason for reinstalling XP in the first place ?
