Error 00a

HP Recommended
250 G4

My laptop also does not recognize my power cord, and upon start up I also have error System Board 00A -System Board CT Number
However, when I turn it off and leave it plugged in, the battery is full when I turn it back on after a few hours. 
But when the laptop is on and plugged in, it looks as if it is not plugged in and functions of of the battery, if i leave the charger plugged in the batter will not decrease but it will not charge either, and the second i unplug it it doesn't recognize the power cable again
Both things accured at the same time (day before yesterday) AND my laptop is super slow all of the sudden.
Regular websites take forever to load and freeze randomly. 
I have used a new power cable and I know it is working as I have used it on another hp laptop. I have taken the battery and power cable out and held power anywhere from 5 seconds to one minute. 

I have reset BIOS to defaut.

I have done hardware checks and they came back with no error.

 

I have a HP 250 G4 that is out or warranty.
