The letter "c" popped off out of the blue when I was typing my document. I figured it shouldn't be an issue because all I had to do was to click it back into its original position. However, the result was different...the key-cap is now loose, and go out of its position even if I just tap onto it. To make matter worse, I tried to re-attach the key by placing pressure onto the retainer and it eventually broke one of the bits that hang onto the metal (not sure how to describe that). I ordered a key-cap from a website called "www.replacementlaptopkeys.com" and received a key-cap from a different laptop... It is supposed to be an A44 key but what I received was a different version of the hinges. I visited "www.laptopkeys.com" and they have A44 size keycap but they do not ship to my country.
May I know if there are any more websites that sell this keycap size? By the way, the model of my Acer Predator laptop is PH317-52.
