BIOS clock not working after Win 7 upgrade

xw4300 workstation was recently updated to Windows 7 from XP pro.  After the update, the system clock was not keeping correct time, so I entered BIOS setup and set time there.  After several hours, I rebooted, entered BIOS setup and noticed BIOS clock had not changed.  I replaced CMOS battery (CR2032) with three different new batteries, and BIOS clock still does not change.

 

Windows 7 system clock will occasionally sync to the BIOS clock, which is creating the incorrect time in Windows. I can see these events in the system event log.

 

Is it possible that this problem is related to the Win 7 upgrade, or is it an unrelated problem?  Any suggestions for testing or fixing the BIOS clock beyond what has been done so far?  If I cannot fix the BIOS clock, is it possible to stop Win 7 from syncing to the BIOS clock?

Re: BIOS clock not working after Win 7 upgrade

This sounds like a serious BIOS issue. You can reflash the BIOS using this update: http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&swItem=wk-656...

 

To keep Windows in sync with some of the most advanced atomic clocks on the planet, if you are connected to the Internet...

 

Click the time on the system tray.

Select Change date and time setting

Click Internet Time

Change setting.

Select Synchronize... If Synchronize is already selected - this may be the problem and you might want to deselect it or select a different time server. You can check by manually changing the time and then clicking the Update now to see if the time changes.

Re: BIOS clock not working after Win 7 upgrade

Thank you for the response.  I have flashed the BIOS and I am running v1.12.  That did not help. 

 

I am also running Chronos to sync every 15 minutes to atomic clocks, but Windows will still sync to the BIOS clock and create invalid times in between.  If I could get Windows to stop syncing to the BIOS clock, my time would stay accurate. 

 

I am guessing that the BIOS Real Time Clock is somehow broken.  Is there any way to test this?  If it is broken, is the only fix a new motherboard?

Re: BIOS clock not working after Win 7 upgrade

Hi,

Remove and replace the CMOS battery. What you reported is the first sign of the battery not reliably supplying current to the CMOS EEPROM. The battery function is to ensure that data that you have configured in BIOS remains the way you set it.

 

The batteries are cheap....just a couple of $$.

The issue you are having is not a  valid reason to  flash the BIOS.

That is rare and unusual. With those symptoms, a BIOS ROM flash is definitely recommended and required. If flashing the BIOS doesn't fix it , then your motherboard has some serious issues and will be the component to suspect as faulty.

Have you flashed a BIOS before?

Re: BIOS clock not working after Win 7 upgrade

As I indicated, the BIOS was flashed to v1.12, but the problem remains.  Are there any utilities to test the BIOS clock?

Did you replace the CLRCMOS or CLRRTC jumper in its original position after you cleared the CMOS and flashed the BIOS? If you did not then the time will be reset every time you power off the PC. 
Does the Date stay current? 
Sorry to have to inform you of this, but the BIOS does not have a clock. :smileywink: 
The Real Time Clock circuit is what keeps real time in a PC motherboard. 
PC Motherboard 101 class begins. :smileyhappy: 
 
RTC (Real time clock) is a function of the motherboard Southbridge chip. If you have updated your motherboard chipset drivers and flashed the BIOS and the BIOS remains unable to keep the time that you set...your Southbrigidge chip is failing and that is an integrated part of your motherboard. That would mean that your motherboard is faulty.

I did not find a CLRRTC jumper on the 4300.  There is a jumper to reset the password (E49), and a CMOS reset button.

 

However, I tried reinstalling the battery with power cord unplugged, and this reset all CMOS anyway.  The reset of CMOS seems to have fixed the problem.  The BIOS clock has now started tracking the correct time again.  I have rebooted multiple times now and the time is holding correctly.

 

Thanks to everyone for your suggestions.

Glad to hear that you are up and running. The BIOS configuration screen gives the user the ability to set the real time clock to local time. The BIOS does not have a clock.
