The Time

You might check the "new" battery. Simply because it is just out of the wrapper doesn't mean it is fully charged or even working at peak efficiency.

It could also be an application or service running on the machine. These will sometimes cause the clock to report an invalid time. If you are sure the battery is working at 100%, try eliminating things like anti-virus software, automatic power management, etc., and see if that doesn't fix the problem. Better yet, try running bare-bones for a while and see if that solves the problem. Then add apps and services back until you notice the time failing to report accurately. That should be your culprit.

Flashing the BIOS might also do some good as there could be known issues with certain hardware/software that has been fixed. Even a M'Board bought today generally has a newer BIOS available on the makers Web Site.

If you have a prebuilt box and not a white Box you'll need to go the systems makers web site for their BIOS update. Either way the Web Site will be in the manual that came with the M'Board or System try that first it is the easiest way to make sure that everything is as up to date as possible.

you did not mention your os? i would update the os to the latest service pack level as this is not a known problem that i am aware of.
except some laptops.
did you check to make sure there isn't a *newer* bios?
read up on the Windows Time Service at support.microsoft.com to see how it works for your os and you will see why you have not provided enuf info for us to guess about what is happening...
how much time is it losing? and is this pc on a network?

Anyone mentioned that the possibility of the CMOS battery needing to be replaced, or is that what you're referring to? Lots of people use the term "PC" to refer to any personal computer, so I thought you might actually be referring to a notebook.

In a desktop PC, it's about the same size as a US nickel and is in a socket on the main board. On my Thinkpad notebook, it's encased in yellow plastic and connects to the board with a 2-pin female connector. I imagine it would look similar with other brands of notebook PC's.

Hi,

I'm wondering if you have PRECISION TIME or similar installed.
This program supposedly links to the Naval observatory, or some similar place to get accurate time ticks. My experience, apart from all the crapware that comes with it, is that it may well get the time tick, but the propagation delay through the internet stuffs up the accuracy. I've experience 10 minute delays.
