My 15v4’s keyboard backlight stopped working. I don’t think it’s a software problem, but if anyone knows how I could test that let me know. It doesn’t respond to Fn+F10, and both Fn and F10 keys are confirmed working. It flickered on and off a bit towards the end of its life.
I’m hoping it’s a loose cable, so my plan is to take the machine apart and make sure all the cables are seated properly in the hope that that fixes the problem.
Any experience with this or other tips?
