T60 clock resets even when windows is working

[The_ShadowWw]

Hi,

my pc clock keeps resetting even when windows is working, every 2 h or so it jumps back to the date I specified in bios last time exp. 2010.05.29  18.18  

it never reaches 20:00 about always about 19:40

I try'd to replace the cmos battery but that didn't.

Is there a chip responsible for the clock, maybe it's fryd, or what els could be wrong

P.S. windows reinstalled several timed, didn't help, bios updated, to new releases, didn't help ether

Hi The_ShadowWw, and welcome to the Lenovo User Community!

Ideas:

Try resetting the BIOS.

You may have a virus.

The replacement battery could be bad or incorrectly installed.

I tried resetting it, even updating to the newest versions.

The battery is 100% good, worked perfectly on other Lenovo.
