Laptop keys can stop working if they have sticky liquids spilt on them or if they are repeatedly pressed too hard. If a keyboard key on your HP Pavilion laptop has become stuck or is no longer functioning, you don't need to replace the keyboard or buy an entirely new laptop. Instead you can pop off the old key and easily replace it with a new one that is working properly after cleaning out whatever substance was causing the key to stick.
Shut off your HP Pavilion laptop's operating system. Push closed the top LCD screen lid, and then flip the laptop upside down.
Push the battery release bar to the right, and then pull the battery out of the HP Pavilion laptop. Flip the laptop back over and open up the LCD screen lid.
Locate the key you want to replace. Slide a thin and flat object, such as a butter knife or the edge of a flat-head screwdriver, underneath the side of the key. Pop the key upward and off the keyboard.
Use a pair of tweezers to remove the small plastic hinge piece if it didn't come off with the key. Dip a cotton swab into a bottle of cleaning alcohol. Wipe off the area where the key was located.
Set the new plastic hinge that came with the replacement key onto the open hole on the keyboard. Set the replacement key onto the keyboard and push down until it snaps into place.
Place the battery back into the HP Pavilion laptop and power the computer on.
You can acquire replacement HP Pavilion laptop keys from online retailers that sell computer parts.
Larger keys such as the spacebar and Shift key may have a plastic bar inside them for support depending on the specific model of HP Pavilion laptop you have. Pull the bar out of the old key and place it inside the new key if it doesn't already have its own bar.
