I have an 820-00239, the client tried to install a new screen with himself,
i believe he didn't disconnect the battery before the installation,
Now there is no image or backlight on screen, I tried 2 screens
no image on external
the fan spin and CPU get hot
USB c 20v/0.8a
battery charge normally
I think the board start
already replaced u8520 and U8500
