When I boot up my Compaq Armada e500, the system time is usually always wrong.  Sometimes by just a few hours, but more often it is set all they way back to January 1980.  Do I need a new CMOS battery?

Hi Snyperj

Sounds like you've hit the nail on the head with needing a new CMOS battery; how are you checking the time? i.e. in windows, or in BIOS at POST?

Hi Snyperj

Are you looking at the clock on the taskbar (bottom-right) when windows is loaded, or when the computer is powered on, are you pressing F2/Del etc to go into the setup program? In the setup program, this will show a true account of the what time the computer thinks it is...

Windows is alerting me when it boots up. with an error message.  Shortly after that my A/V program goes haywire saying the definition file is out of date and the license is out of date, etc etc.

The AV program is just responding to the fact that the time has changed. (At least according to windows).

Restart your system, then straight away when it boots you will see a prompt to press F2 or Delete to enter setup; press whatever the prompt is for. (If you hammer away at F2 or Del then this usually works).

Once you're into the setup program (probably very simple text on a blue background), look for something thats telling you the date - if this is correct, then windows is wrong - possibly the result of a virus or misconfiguration. If the time/date is incorrect in setup, then the battery is dying..
