Product: Product number: 5NL15AV, HP Pavilion 15t-cs200 CTO
Operating System: Microsoft Windows 11

Product number: 5NL15AV, Serial number: [personal info removed], HP Pavilion 15t-cs200 CTO

 

I started getting this message for the past 1 week.

 

The CMOS checksum is invalid. The CMOS will be reset to default configuration and will be rebooted. CMOS reset 502.

 

If the power cable is plugged in only i see the error. If i remove the power cable it suddenly shuts off. Can you please help.

I suggest recovering the BIO by holding down the Ctrl key + the B key while starting the notebook.

 

Do not release the Ctrl+B until the notebook responds.

 

It may take a minute or so.
