I changed the motherboard, which subsequently changed the bios and the whole system. My backlight stopped working and I tried everything to get it working again.
I had W10, I had W8.1. I tried all drivers combination, everything and nothing worked.

Then one day I check on the net and find this video and it helped me! My f3 and f4 are switched and it doesnt work exactly as it did before but I still have 3 stages of lights and everything is back to working condition!


Hope this video helps you too!
