My keyboard backlight was working fine but then one day it just stopped.
I've pushed f10 and fn + f10 doesn't give any feedback
I've gone to the Windows mobility center and made sure things are fine there but still no feedback.
When i push the f10 key the setting in windows mobility center changes but it shows no light on the keyboard
But the CAPS LOCK Light and back light works
Apart from that nothing else
Tried restarting also no feedback from the lights
Also could it have been a recent update that might've caused this?
Is there a driver for this?
Does the keyboard backlight come on when the system is powered up? If it does, you may have a software issue.
If it does not, you have a hardware problem.
First thing to check is that the backlight cable is firmly connected to the system board (this will require removing the keyboard to check).
Check to make sure the cables are firmly connected to the mainboard - if that doesn't solve the problem, on this model, the keyboard and palmrest are a single unit that must be replaced together.
