I have certain keys that are hard to work
I need to know what screws I do and do not need to undo to get access to the key matrix and clean it. Top keyboard 1-3, and F1-F4 keys, as well as the area around the “P” key, and backspace key have to be held down, or tapped multiple times to get work. Please help! I have 2 small children and lots of sugary drinks.
