I don't know if anyone else has encountered this, but lately the LEDs on my deck have been going out one by one but will sometimes come back very dim or at about half intensity. However once this happens to a key, they never come back to "full life". It's been about two weeks since this occurred and currently there are six keys out and five keys at half intensity. They seem to be randomly distributed and not clustered in one area. Does anyone know what could be happening or how to fix it? Also my power supply is fine and I have tried the keyboard on other computers with the same result.
