hi, my M500 has started to develop LCD brightness flickering, all the characters etc are ok but there is flickering at times. Also the brightness is not at the level it was before (if I go above 50 on brightness it stays the same). I had a look through the forum but found some brief mention of this but more about full LCD failure. Could this be a power/PSU issue?
Any advice would be appreciated. The unit otherwise works well.
