A laptop mouse or touchpad works by scrolling or clicking on the keys to navigate the computer screen. Dirty hands, body oils, food particles or liquids, and dust can build up in between the mouse keys. This excess residue can cause the keys to stick. Cleaning the keys typically solves the problem and requires just a few materials to restore the pad to proper working condition.
Power off the laptop and unplug it from the electrical socket. Remove any external devices, such as a printer, headphones or flash drive.
Hold a can of compressed air at an angle and spray into the cracks around the stuck mouse keys. The compressed air should dislodge dust or other particles from the keys.
Insert a toothpick into the cracks to remove any visible debris that may be stuck, being careful to avoid probing too deep.
Wet a soft cloth slightly with Isopropyl alcohol. Wipe the keys to clean up any surface debris.
Dampen a cotton swab with alcohol, but do not soak. Carefully wipe the edges of the keys to remove any remaining debris.
Do not soak the mouse key in alcohol.
