Recently, the LED in my '''''CapsLk''''' key has refused to turn off. Before, it would light up when caps were on, but go back to being dim when caps was off—then I tried “press and hold”, but now the light just stays dim and flickers when I type different keys.
The issue started yesterday; and my laptop had ended up dying, so when I turned it on, I still had the same problem. I was told it might need cleaning, but I’m not sure what exactly I’m doing. Any advice would help.
