I believe this is a hardware(Possibly software?) issue due to me being able to use an external keyboard and all of these keys working. Recently, a couple days ago I had decided to use disinfectant wipes to wipe my keyboard due to some kids at my table spilling a little bit of ice/juice onto my keyboard(The keyboard still worked fine and I wiped it maybe two days after the semi sticky keys being annoying). I wiped my keyboard while the computer was on and basically just button mashed swiped it. After this the keys acted weird. Certain keys did not work but others did. I have already deleted the drivers for the keyboard(and they restored) and I have opened up the keys that did not work. I recently bought this laptop and am in need of some serious help! Anything will be helpful!!.
