Thinkpad Yoga (20CD) trackpad and keyboard backlight still not working after being replaced. STUMPED

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.

Also I've done various system restores and reinstalled Windows 8.1
