Chosen Solution
Hey, I bought a used keyboard and I realised that the arrow keys are not working properly. The left and up arrow keys work only if I press them stronger (the left one also works effortlessly if I press it on the left side of the key). Any clues on how to solve it?
Should I try to disassemble it and clean it or what? Thanks in advance for your assistance.
Try removing the broken arrow keys and cleaning the insides of them. Make sure the piece of the key that presses down on the button is not broken.
