My laptop keyboard back light is always on. Only when my laptop is asleep or turned off the back light. I tried to use the normal method - fn f3 - not working. I couldn’t find a property in the computer that can change it. Thank you, good luck.
Good luck! I wish I could get my Dell keyboard to stay lit longer than 10 seconds when not depressing any keys. When did this first occur?Have you looked at the Administrative Events?Do all your keys function properly?Have you checked your owners manual/PDFHave you tried reverting back to an earlier driver through the Device Manager?
