The keys on the keyboard can either not be pressed fully or when pressed fully do not do their intended function.  

We must first address the state of the external components to our keyboard. First look to see if there is any dust, dirt, debris, or sludge on the keyboard. If any of these happens to be on the keyboard it could potentially block the key from pressing the button it is indicating fully. After locating any potential issues, turn the laptop off using the button ribbon on the computer. Left-click the windows icon, click the power icon, then select shut down. Once powered off we can begin cleaning the keyboard by using a towel or microfiber cloth to wipe off debris and dust. To clean any sludge or sticky keys, we can use a lint-free cotton swab and isopropyl alcohol to lightly scrub away. Do not soak the swabs in alcohol because you may damage your keyboard with excess liquid; instead, lightly dab the swab into the alcohol, then start scrubbing. Make sure to let the keyboard fully dry before testing. If keys are still stuck after cleaning, some keys may need additional cleaning or debris clearing. To clear these problematic keys, you may need help from additional tools such as canned CO2 air or specific keyboard cleaning brushes.
