Keyboard/Keys Not Responding
The keys on your keyboard won't respond or appear to be broken or missing.
If the entire keyboard fails to respond, try replacing it with this guide.
Keys are stuck in place. When keys can't be pressed, there may be something below the physical key holding it up. Try using an air duster to clean the underneath of the key. If this fails to work, unfortunately on this keyboard the individual keys do not come off, so you will have to replace the entire keyboard using this guide.
