HP Recommended
Product: HP Pavilion - 15-cs0854nd

Hi everyone,

I am having problems with my HP pavilion 15. When I work on the laptop in the charger, it seems to work fine. However, as soon as I disconnect the charger the laptop will shut down within an hour. Only when connected to the charger again it will restart and show the 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'' To fix this problem, I already tried resetting my BIOS and replacing the CMOS, but this laptop does not seem to have a CMOS (directly visible). How can I fix this? I thank you in advance for the help.
