A Toshiba Portege R835 keyboard was having issues with the "A" key. When attempting to fix the key, I pulled off the "A" key and readjusted the rubber actuator for the "A" key. This made the situation WORSE. Not recommended. This resulted in the purchase of a NEW Toshiba Portege R835 keyboard.
Originally, I thought that the Portege R835 was well built, but after replacing the keyboard, I take it back. Why? THE KEYBOARD IS GLUED ON. What a mess. Taking off the keyboard damaged the original keyboard.
