Question about RTC Battery (CMOS Battery) and System Errors

hp 2510p
Microsoft Windows 7 (32-bit)

Been working fine until a few days ago. When I turn it on it says

 

163 - Time and Date not set - There is no option in bios to set date

 

Non-System disk or disk error replace and strike any key when ready - Bios cannot detect hard drive

 

So the question is if the RTC Battery is weak or dead can it cause above issues

 

Thanks 

Chris

Question about RTC Battery (CMOS Battery) and System Errors

Hello;

Allow me to welcome you to the HP forums!

The answer is actually -- yes and no.

 

A weak or dead CMOS battery will prevent the BIOS settings from being saved when you power off the PC.

 

If the default settings work OK with your hardware, then the only thing you would notice is that the clock resets.

 

But, if you customized your settings to see the hard drive, then the default settings might not see it.

 

After you replace the battery, you would have to go through configuring the settings-- again.


Good Luck
