Laptop goes black screen on me but I hear the fan on

HP Envy x360 Convertible 15m-bp0xx
Microsoft Windows 10 (64-bit)

The laptop after a windows update would not show me the display. Then I did some research online and it said that after a windows update this can happen. It suggested to update the video card driver which I did. Also to do a BIOS recovery which I also did. After the BIOS recover everything went back to normal. Inl tested it for a few days and everything seemed to be back to normal. Then I gave laptop back to my wife and afte Rhee first use no display problem returned but it was a little different. It said this


CMOS Reset (502) The CMOS CHEKSUM is Invalid


It asked me to press enter and then after a few attempts at reboot it came back on. Does anyone have an idea with what is going on? I would really appreciate insight in this matter.
