CMOS 502

[MarkDFS]

Hi everyone 

I have an HP Laptop 14s-CF1012TU running on windows 10 pro 64bit.

I have a problem, My laptop doesn't turn on when you press the power button. But once you've plugged it in , the Laptop will turn on when you press the power button. Now everytime I want to use my Laptop, i need to plug it in first so it will turn on.

Now, everytime it will turn on It will flash a black screen. With a message:

The CMOS Checksum in invalid. the cmos will reset to the default config....... Etc....

CMOS Reset (502)

Press enter to boot the system.

Now when the System booted into windows, My time and date is always set to 1998, I dont know why . 

I tried to reseat/replace the CMOS battery, but when i open the motherboard , there is NO CMOS in my Laptop.

I already update the Bios Version, still the problem persist. 

I hope someone could help me.
