Simultaniously my keyboard backlight, touchpoint and trackpad stopped working. They do not appear in device manager and reinstalling drivers did nothing.
On Lenovos advice, I purchased replacement palmrest, trackpad, keyboard etc and fitted them successfully but this has made no difference.
Could it be a power management issue? I've updated PM drivers. Motherboard damage? As far as I know no water or physical damage has occurred.
