System board CT Number Missing or Invalid

HP Recommended
HP-15 ac134ne
Microsoft Windows 10 (64-bit)

Whenever I start my notebook I get this warning.

 

The following programmed into the system board is invalid or missing

system board(00A)-system board ct number.

 

this only happens when I start my laptop with my charger plugged in and it also throttles my cpu speed to 0.48ghz.

 

when on battery is pc starts up fine with no warning.

 

its confusing me that my pc starts up and cpu runs normally if its all on battery but throttles the cpu speed when plugged in

 

Specs are;

core i3 5005u 2.00ghz

12gb ram ddr3

intel hd 5500

 

please help me fix this as my battery isn't that good and I have to keep it plugged in most of the time but it wont even charge when turned on cause of this....it only charges when it is turned off or in sleep mode.
