There is a key stuck in the laptop
If a key has been physically jammed in the pressed position, you may not need to replace the laptop. On many keyboards, the keys can be removed by inserting a knife to spread under the top or bottom edge and lifting gently. Once you have removed the key, use a swab with alcohol to clean the bottom of the key and the corresponding slot on the keyboard. Press the key again pressing it to snap into place.
ATTENTION:If the laptop is still under warranty and there is a jammed key, you should contact HP to see if they can repair the laptop before removing the key.
ATTENTION:To avoid damaging the pad under the key, insert the knife to spread only 2 centimeters below the edge of the key.

Turn off the notebook and disconnect the AC adapter before working on the keyboard.
If the notebook has a removable battery, remove the battery before removing the key.
