Cant open my notebook after updating the BIOS/Chips Driver( System board (00A) CT Number)

[DavidCheung9999]

My notebook is PAVILION 15 which was bought in 2016. I use the HP software to find my notebook model and try to update the drivers(chips/bios). After finishing update and reboot my computer. It cannot turn on properly and shows the message  "System board (00A) CT Number)". What can I do??

Somehow I finally can boot my notebook up. I try to press the window + V and the power button. The notebook does not turn on properly but with a different error message "CMOS Reset (502)".  After reboot the computer again it can run into the window and now I can use it. 

However, I am afraid the nb cannot turn on again after turning off. Should I update the bios/chips driver again? Or what can I do?? Many Thanks
