1 Backlight on/off becoming less sensitive over time
As above, is there anything I can do to improve the sensitivity of the keyboard? It used to be that as my hands neared the keyboard, the backlight would come on, but nowadays if have to physically touch the keyboard, and even then I have to sort of wipe my hand from left to right to get it to notice my hand and turn the backlight on. I'm guessing there's some kind of sensor somewhere that's getting blocked over time?

En el otro K800 viejo que tengo la iluminación no obedece únicamente al sensor, sino que aunque no haya nadie cera se enciende y apaga como una árbol de navidad.
Y la tecla Alt no le funciona.
