HP 250 G6 Notebook PC
Microsoft Windows 10 (64-bit)

Hello. Help me, please! 

I have a problem with my HP 250 G6 Notebook PC. When it works from the battery it suddenly shuts down and after I use the charger. It starts but this error shows: 

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 changed.
CMOS Reset (502)
ENTER - Reboot the system

So the laptop starts after resetting it. There are some problems with time. It's incorrect and not updated. I do it manually. 

Help!!!Please!
