For some reason, the keyboard buttons that are supposed to adjust the backlight on the keyboard (keys f3 and f4) are no longer adjusting it. The keys themselves still work fine, but when I hold fn and try to adjust the backlight, it doesn't get any brighter.
I'm not sure how to fix it. This is a brand new laptop, and it's worked fine for the past couple of months, but it suddenly stopped working. I also can't seem to find any setting in Windows 10 relating to the keyboard backlight. What should I do? Thanks for the help!
