Keyboard backlight dimmer only on some function keys
So I've got a very weird issue. And I'm curious if you guys think it could be the keyboard itself (maybe it needs replacement) or maybe something else.
The issue: the backlight on some of the FN keys is dimmer compared to the rest of the keyboard, or the FN keys next to them.
But here's the tricky part. It's only one in two keys that has this issue.
Basically, keys ESC, F2, F4, F6, F8, F10, F12 have a dimmer light.
Whereas the rest of them (F1, F3, F5, F7, F9, F11, POWER, along with the rest of the keyboard), have a normal light.
There is no functionality issue with these keys. They all react properly. It's just the backlight that's weird.
Any idea what could cause this? I've never seen this issue before. I was hoping maybe one of you guys had.
Also, for as far as I could see on the internet, the liquid damage affects the keyboard in a different way. The keys in the middle of the keyboard light up more than the rest of them. It's not one every two keys. And only the function keys.
The laptop is not new, is not under warranty. And to my knowledge, it has no liquid damage.
Here's a picture of the issue.
Fixed by readjusting the backlight flex cable connector into its socket. Yeah, that easy.
