Step 1:Cleaning
the Keys
Before
you begin, unplug the keyboard or remove the batteries. If using a laptop, shut
it down and unplug it. Pick a can up from an office supply store and spray
around the base of each stuck key to dislodge dust and debris. If you don't
have compressed air, turn the keyboard upside down and tap the back while
shaking gently. Dampen a cotton swab or clean cloth with isopropyl alcohol. Run
it around the edge of each key to remove grease and dried liquid. Some people
have reported success with baby oil, but it can remain in your keyboard, so use
at your own risk. If you can see the debris underneath the key, use the
toothpick or straightened paper clip to dislodge it.
Step 2:Cleaning
Under the Keys
If
you need to remove more than a few keys, take a photograph first so you
remember which key goes where. Before you continue, unplug the keyboard, Most
laptops have keys that are difficult or impossible to remove. In these cases,
you'll need a guide or advice specific to your laptop model, or you'll need to
have your laptop professionally repaired. On desktop keyboards, the outer key
covering can usually be pried up easily with a flat-head screwdriver. Most
debris is found in the letters and numbers. Other keys tend to be less dirty
and more difficult to replace after removal, especially the space bar. Use
compressed air to remove exposed dust and debris, and a cloth dampened with
isopropyl alcohol to remove stickiness and stains. For laptop keyboards and
other keyboards with delicate internal parts, use gentle swabbing only. If the
underside of your keys are discolored or dirty, put them in a colander and run
water over them, or rub them in a bucket of soapy water. Let them air dry
completely on a paper towel.Try this technique if your laptop key raises or
lowers extra slowly. After removing the key, look for a square plastic object
around the button. Remove this gently by pushing the corners sideways with a
toothpick. Rinse this in water to clean the hinge, then let air dry. On a
Macbook, the catch that holds these hinges in place are on the lower left and
right.Let all the keys dry, then push them down over the buttons to reattach
them. Let the keyboard dry overnight before you use it.
Step 3:Fixing
Hardware and Software Issues
If
you only have keyboard problems when using a single application, you'll need to
look for help fixing that software issue.Inconsistent results from keystrokes
can be caused by low battery power. USB keyboards work best when plugged directly
into the computer, not into a hub, keylogger, or other device.Keyboards with a
circular, six-pin PS/2 plug sometimes encounter errors if they are connected
while the computer is on. Shut down the computer, disconnect the keyboard, and
reconnect it again.If some of your laptop keys don't register when pressed,
there could be a loose internal connection. Unless you have a guide for your
model and are comfortable disassembling your laptop yourself, you should take
it to a professional.
