Cmos checksum is invalid error Cmos reset 502

HP Recommended
HP-15-DA0014NE
Microsoft Windows 10 (64-bit)

I have recently replaced my batter and after that whenever I press the power button it doesn't go on, I will have to connect the charger then I will hear small beeb then get this black screen with this error "the cmos checksum is invalid, Cmos reset 502" 

When I reboot the laptop boots just fine, I have checked my system time and it is OK.

Can anybody help me in this please?!
