Please fix the system of the latest firmware of Acer 515-56 or known as aspire 5. The keyboard is misbehaving. When you press "rt" it will continuously type "rttttttttttttttt...". The only way to stop it is to spam press "rt" on the keyboard. I had identified this problem. Since I reinstalled windows lower than the latest. The keyboard works perfectly fine. So I therefore conclude the latest update is bugging on keyboard. Please raise an issue and make a bug fix of it. Now my laptop automatically updated again and it's irritating me. It's not on the connection of the keyboard guys it's on the firmware they released
