I am getting the error CMOS Checksum is invalid. I have attached the error message. Moreover, timings in my laptop are not accurate, my laptop suddenly closes if I remove it from charging after 30 mins exactly. According to me, there is some issue regarding the CMOS only. I have rewritten the bios image several times, updated it, and still getting the same error.

Laptop model: HP Pavilion 15-CC102TX

Solution
Not all laptops have a removable CMOS battery that is easily seen, some of them are soldered to the motherboard. Check the service manual for your model or check on the HP support site.
