W,E,Y,P,L keys on Slim Folio Pro 11" dosn't work

As the title says: W,E,Y,P,L keys on Slim Folio Pro 11" dosn't work.

Additionally power button doesn't turn the light on when pressed. Only when the device charges.

I paired it many times, reset it etc.

The local service couldn't help me. Any ideas?
