Windows 10: CMOS error

CMOS error message how to fix

:)

 

CMOS Reset (502) + No Wifi Options + No Battery Charge

I have an HP Envy x360 Convertible running Windows 11 version 21H2 with the following issues:

• Boots to blue screen"CMOS Reset (502) The CMOS checksum is invalid" and then proceeds to normal OS except:
  
• Network & Internet will not detect any wifi network (though there are several available) Device manager shows intel(r) wifi-6 ax200 = This device cannot start (Code 10). Rollback Driver in device management is no longer an available option.
  
• Power detects the charger while connected but unit immediately loses power once disconnected.
  

Troubleshooting steps completed:

• Multiple hardware diagnostic tests with no indication of issue
  
• Rollback for drivers (doing this would allow an internet connection but power issues persisted)
  
• Complete factory reset & OS reinstall (locally, without USB)
  

What are my next steps to avoid unnecessary cost and/or further trial & error:

• Restore to new OS from USB?
  
• Go somewhere for more thorough hardware diagnostic?
  

Thank you !

 

CMOS Error...

My Asus Maximus SE refuses to Post now....

It goes through the usual checks and stops showing CMOS Error on LCD Poster...

I've tried resetting BIOS, removing battery overnight....

Is there anything else I can try or is this now a dead Asus?

 

clear CMOS

As @Law- II said .....

please fill your system specs.
If you have a desktop motherboard i would suggest to see if you CMOS battery is not dead.
