Date/time defauting to Dec 2000 (by 2 users)

posted by Matzke on Jul 14, 2007


Whenever I log on after the computer has been turned off, the date defaults to December 2000. It appears to be a millenium issue.

I have tried the setting to ON for "Automatically synchronize with an internet time server" and also tried with that unchecked..........neither solves the problem. The machine seems to run slower until I correct the time/date to current.

What should I try?

Changing the battery was my second option, did not have to go there. From hp.com, an easier solution that I thought I would try was to remove and reinstall Realtime clock. Did that and it was solved.

Thanks to all.

Follow up comment: The clock worked the first time that I started my computer from being off. But the next time that I powered it up, it went back to the December 2000 date.

I will try updating my BIOS or changing the battery on the mother board.

Change the "battery" on the mother board. Sounds like it's weak and there's not enough voltage to maintain the BIOS memory.

Also see if you have the latest BIOS version.

Good luck

The bios battery could have been drained up. Replacing the battery is the only solution.

Remove the side cover of your computer, on the motherboard you can see a silver color round shaped object, thats the battery. Remove it, you may have to use a screw driver to pull it out. Note the code written on the battery and purchase a same one. Put the new battery on the motherboard. Make sure that the +ve discharge should come on the top.

Hello
It may be of the defective CMOS battery inside the CPU.
Change the battery and set the time once and restart the system.

Hello
I think its the CMOS battery problem
1. Remove the top or side cover of the CPU
2. Look into the mother board.  You can see a CMOS battery which is upto size of 50np.
3.  Remove it carefully and replace the same
