At different times, keys on my keyboard won’t work. It doesn’t matter how many times or how hard you push, they don’t work. Other times a key will be too sensitive and put two characters instead of just one. It’s never the whole keyboard at once, only occasional keys. It doesn’t matter what application I’m on. There’s no excess amount of dirt under the keys. I didn’t spill any liquid on the keyboard. What do I do?
