CMOS battery?

My Dell Dimension XPS D300 is powered on all the time but seems to keep losing time. Would this be a sign of a dying CMOS battery even though my computer is always on?

    Could be, although if you've made any recent changes to your Anti Virus program in the way of updates/engine upgrades, that's another possible suspect. If you're still working with the original system battery, that would be the first thing to look at.

    If the PC is powered on all of the time, it is not the battery. The PC only uses the battery when it is powered off.

    Just about any battery (including those used as system batteries, such as the CR2032) will degrade over time, whether it's in use or not. Given the age of the system, and given the probablility that the system is in fact turned off occasionally, even if only during power failures, the battery should not be ruled out so blithely.

    The battery may degrade if it's not in use, however if the system is powered on and losing time it's not the battery.

    If the system lost time every time it was booted up then I would say check out the CMOS battery, however in this case it's not the battery.

    Do you use XP on your system? I know that the XP Internet Time Synchronization thing is always making people lose time on their computer clocks... So if you have that on then uncheck Internet Synchronization off and reset your time, that will probably work. (To do this, double click the clock then select the "Internet Time" tab, then uncheck "Automatically synchronize time...").

    If this is the original battery...replace it regardless of timing issues.

    I suspect that the anitivirus update may have been the problem. I am still using the original battery with the original Windows 95. My computer is on UPS and didn't experience any power failures during the period that I was losing time. I actually lost time during the day. I would reset the time in the morning, then by afternoon, my time would be off by at least twenty minutes.
    Yetserday, I reset the time then rebooted the machine. Up till this morning, the time is still correct. Let's hope it continues that way.

    Thanks all for your comments. I presented all the same arguments to myself about the battery but needed confirmation.
