My screen flickered and then blacked out. I had a hub hooked up with two other monitors, but I can't get a picture on any of them. I took the bat cover off and remove the battery. Now when I turn it back on, I get this message and then the screen goes blank again.
The CMOS checksum is invalid. The CMOS will be reset to the default configuration . and will be rebooted. Please check Setup options to see if they change.
CHOS Reset (502)
ENTER - Reboot the system

Hi @Church4uok
most probably your laptop model has the CMOS battery integrated in the main battery, and then when you remove the battery you get this error.
