Hi all,

 

I got "CMOS Reset(502) The CMOS checksum in invalid" error during boot and the laptop shutdown itself.

So I am trying to update/install bios through USB. while doing it is writing the image fine but during bios verification the laptop shuts down automatically.

 

anything am I missing here?

 

Please help me with this, thanks.
