CMOS Checksum Invalid Error on HP Victus 16 S1034nf

[Makunochi225]

Hello,

I hope you're doing well. I have an HP Victus 16 S1034nf (Ryzen 5 8645hs, RTX 4060 120w, 165hz display), purchased new three months ago.
I frequently encounter the following error when powering on the laptop :

The CMOS checksum is invalid. The CMOS will be reset to the default configuration, and the computer will restart. Afterwards, please check the BIOS Setup options to see if they change.
CMOS Reset (502)
ENTER – Restart the system
For more information, please visit: http://www.hp.com/go/500bioserror  

After this message, the computer restarts, and all BIOS settings revert to default, including the system clock, which is no longer accurate.

Based on my research, this model does not have a dedicated CMOS battery. Instead, the main laptop battery maintains the BIOS settings. If the main battery is completely discharged or removed, these settings may be lost. However, I always use the laptop plugged into AC power, and it has never been fully discharged. The battery appears to be in good condition.

How can I resolve this issue? Do I necessarily need to replace the battery, even though it seems to be working fine?

Thank you in advance for your assistance.

First, try following these steps to update the BIOS. If the problem persists, test the battery.
