Battery Icon is in system tray on plugged in Desktop using Vista U

[longbowbbs]

I have an HP desktop which is always plugged in. In the system tray the
Battery icon is active and for some reason Windows thinks it is on a laptop
using the battery. Some diagnostics will not run in battery mode so I can't
run them when it THINKS I am on battery. How do I get the sytem to understand
it is not a laptop and it is plugged in?

Do you have a UPS connected to the PC with its data cable? That will
correctly show a battery icon in the notification area. The Power settings
refer to running the computer from the UPS battery during A/C blackout
periods.
