The keyboard SuuuCKS.Only 3 years old? Mine is about 6 yo and works like a champ. Spilled coffee on it once and ruined the keyboard but Youtube saved the day. I actually found a video of a guy replacing his keyboard on the very same model laptop that I own. Be careful buying laptop keyboards on Amazon. Apparently in some countries the key layout is slightly different. It took me two tries to get the correct OEM style keyboard but the operation was easy peasy. Much less stressful than trying to work with a crappy keyboard.
