Many laptop users must deal with keys falling off their computer's keyboard. This can be a nuisance, but it's easy to repair. While the methods differ slightly depending on the size of the specific key, reinstalling a key on your HP laptop should take no more than 10 minutes. If you lose a key, many online retailers specialise in selling replacement keys for specific keyboards.
Locate the plastic hinge that attaches underneath the key. This small piece comes apart into two sections and must be assembled correctly. For reference on how to properly assemble it, gently remove the key next to the one you're replacing to study how the hinge is oriented.
Hook the lower side of the hinge to the two lower metal hooks on the exposed keyboard area once you've got the hinge oriented correctly. Press down on either top corner of the hinge to snap that side into place before repeating for the other side. If you've oriented and installed the hinge correctly, you should be able to pivot it up and down on both sides.
Locate the rubber spring that fits in the middle of the hinge's hole. If the spring came off the keyboard, place it back in the hole. The key will hold the spring in place, so you don't need to snap it down.
Align the key over the exposed area and press down on it evenly until all four corners snap into place. The key should now be sturdy and attached to the keyboard. Also, replace any other keys you took off for reference.
Locate the metal bar secured to the bottom of the key. These are usually found on long keys, such as "Enter," "Backspace" and the space bar. Disconnect the metal wire from the key using the flat head screwdriver.
Orient the metal bar so the long section is facing you (away from the screen), then slide both top sides into the small hooks on the exposed keyboard.
Place the space bar or other key over the correct spot and press it--gently and evenly--until you hear or feel it snap back into place.
If you can't afford any replacement keys right now, you can always replace an important letter key with a less important key. For example, if you rarely use the tilde key, you can remove it and use it as a makeshift "R" key if you've lost your "R."
