Windows XP reports that my mobo supports APM, and the APM tab is present in Advanced Power Settings, but when I tick the enable APM support and Apply the tick refuses to stay there.

I am guessing this is why my PC does not power off automatically on shutdown - I have to hold the power button in for 4 seconds to achieve this.

Anyone know of a fix?

Try going to device manager and "view/show hidden devices". See if anything is disabled.

Nothing disabled, but I do not see an APM device there either

you might wanna look up your motherboard website for any drivers for either APM or ACPI. ACPI support would be better coz it's a newer power management. check your BIOS if APM/ACPI is enable as well.

I think that XP only does the turning itself off thing if you are using one of the ACPI HALs. Generally it decides during setup if it thinks your motherboard supports it. You can force it to change HALs but theres not guarantee that it will work properly (or even boot) if forced on to the ACPI HAL.
