Check keyboard mat

  • Check the rubber mat for damage or obstruction at the location of non-functioning buttons.

  • Flip the mat over to assess dirt and damage.

  • Replace the mat if it is damaged.

  • Clean off the back of the Motherboard as necessary. The mat lies on top, so dirt and debris may build up. Repeat cleaning as needed.
