I have a Asus w3000 laptop. The keyboard works fine but the “A” key does not work. Does anybody know of a website that can show me how to open up a Asus w3000. I need some help. Please!
You dont need to open the laptop! 
Just get a flat headed screw driver… place it under one side of the key and turn!
and don’t worry the A key will click back into place when you line it up and press, when your putting it back
