There appears to be a failure related to the keyboard controller

Explanation: An error message or keyboard failure is implicating a possible failure of the keyboard controller chip on the motherboard.

Diagnosis: The keyboard controller chip can indeed develop a problem, although this is unusual. Using the wrong kind of keyboard, or a defective or incorrectly connected keyboard can also cause an apparent problem with the controller.

Recommendation:

  • Troubleshoot the keyboard itself first.
  • Find the keyboard controller chip on the motherboard, and examine it. See if it looks damaged in any way. If it is, then it needs to be replaced (either that or the whole motherboard). You may be able to get a new controller chip, but you will have to contact your motherboard's technical support department.
  • If the controller chip is socketed, check to see if it is fully in the socket. Gently but firmly push down on the chip. You may hear a "crackling" sound when you do this, which is fairly normal. This may resolve the problem.
  • Troubleshoot the motherboard.
