I've got a HP laptop, and lately the left and right arrow keys on its built-in keyboard have inexplicably given out. Pressing either one of them just triggers a random smattering of other keys instead. (A few presses of the left arrow key does this: http/i.imgur.com/WX3b0zN.png and a few presses of the right arrow key do this: http/i.imgur.com/MdqGz4p.png). I'm not having issues with any other keys on my keyboard but those two arrow keys. Does anyone know what the issue is?
