Battery Power Management Options Gone

In my task bar I have the Power Options Icon, which when double clicked opens the properties.  All was fine until I formatted awhile back, and it now has different options (although I reinstalled Windows 2000 Pro from the same cd).  The icon doesn't change to a battery when running on the laptop battery anymore like it used to, the options for setting low battery alarms is gone, some new ups battery backup options are there, etc.  How do I go about getting my previous options back?

It should detect its ACPI when you install it in the first place!

No you must reinstall as its a different HAL.  When you boot up you need to press F5 (I think) and you can select the type of hardware you have from a list.  Make sure ACPI is enabled in the BIOS though as that may be why it wasn't recognised.

It sounds like some additional software has been installed for your laptop like the OEM Power management.

Check the Add/Remove Programs for such programs and uninstall them.

Looked through the whole list...nothing that looks like Power Management. :-(

Well, I think I found the problem.  See http://swexpert.com/C5/SE.C5.JUL.00.pdf

It seems that when I reinstalled Windows 2000 Pro, I must have set it up without ACPI, whereas when I got it it probably had ACPI.  This is confirmed with the fact (as it describes in the link) that I had "standby" under Start>>Shut Down before the reinstall, and now it's gone.  Bad news is it seems you have to reinstall the OS to get it back. :-(  If anyone knows how to enable ACPI without having to resinstall Windows, I'd be *greatly* appreciative!!!
