The CMOS checksum is invalid

[Liz_Candy321]

I own an HP Laptop 15-dy1xxx. It runs on Windows 11.

Every time i use my laptop it randomly shuts off at around 70% of battery percentage. I have to plug it in to a power source in order for it to turn on again. It fully charges, and when i disconnect it it shuts off again when it reaches about 70%.

Once i reboot it i get the following message:

The CMOS checksum is invalid. The CMOS will be reset to the default configuration and will be rebooted. Please check your BIOS Setup options to see if they change.

CMOS Reset (502)

ENTER - Reboot the system

For more information, please visit: www.hp.com/go/techcenter/startup

I have tried so many things to get this resolved. I went to the support website for Software and Drivers and i put in my laptops information but when it asks for OS, i only get the windows 10 option. I am unable to see a windows 11 option.

If there is one that exists for windows 11 please share it with me. According to my System Information my current BIOS is F.28 - 03/07/2023.

Any and all replies will be greatly appreciated.

Thank you!
