Aerobook Plus - Keyboard Key Not Working - One row of Keys not working

On Aerobook Plus, facing the issue that one row of keyboard keys (R,T,Y,U,I) have stopped working. Tried all, updating drivers, updating Windows etc, but nothing worked.
How to fix this.

Also, what is the keyboard configuration for Aerobook plus, incase i want to purchase it outside. Configuration or Keyboard details so that i can try searching outside.
