CMOS checksum is invalid

[RickRodri95]

It’s been giving this problem 3 times, the laptop turns off then won’t turn on, it charges and when I press the power button it blinks once and doesn’t turn on. Then several days later it turns on and gives me the CMOS checksum is invalid and when the laptop gets shut down again it won’t turn on and it’s the same problem blinking light and turns on several days later with the same error
