Sony VAIO (Model # VPCF 136FX) Backlit Keyboard Not Lighting Up when Dark

I just sent my laptop in for repair to Sony to repair a power failure condition and when it came back my backlit keyboard function (keyboard lights up in the dark) is no longer working?

 

My labtop also updates to the Sony website and may have installed some software updates which may have disabled the backlit keyboard function.

Can you help?

rpalermo,

 

Make sure that the ambient light sensor (to the left of the numlock indicator) is not blocked and that in VAIO Control Center under Keyboard and Mouse that the option is enable.  Try covering the ambient light sensor and see if your keyboard backlight will turn on also.  If it does not there might be an issue with the backlight function..
