Keyboard Backlight not working.

On my Asus FX550VX I cannot turn on the keyboard backlight. The fn+F4 or the fn+F3 does not turn it on or off. fn+F3 opens the outlook mail and the fn+F4 opens my browser. How do I turn on the keyboard backlight?

If you have Win 10 installed, try updating the ATK package and Smart Gesture drivers and see if this resolves the problem.

Be sure to update the ATK package first before the Smart Gesture drivers.

Here is a link to the latest Asus Win 10 drivers

Be aware of the Notes: near the top of the page in the link, regarding installation of the drivers. Also do not be tempted to update all the relevant drivers found on this link. It may confuse the issue if you run into problems. Work on one problem at a time. As the saying goes "If it ain't broke don't fix it"
