Fix Computer Keyboard Problems

The following are some helpful hints for basic keyboard care, as well as some common troubleshooting problems and possible solutions.

When it comes to their computers, many people take their keyboards for granted. However, the keyboard is an integral part of your computer (read: it’s hard to input anything without one!), so some care must be exercised when using it. The following are some helpful hints for basic keyboard care, as well as some common troubleshooting problems and possible solutions.

Keyboard Is Dirty -How to clean up keyboard
Keyboards should be cleaned with "spray-n-wipe" cleaner and a cloth or tissue on a monthly basis. Ensure that computer is not powered up while cleaning the keyboard. Compressed air can also be used to clean between the keyboard keys. Another tip: clean the keys with a cotton swab dipped in alcohol. Compressed air is best way to clean computer keyboards.

Keyboard Not Found" Message
Your keyboard is not plugged into the computer securely. Unplug it and plug it back in and the problem should go away. If this doesn't work, follow procedure: “Computer isn't taking inputs from keyboard” (below).

Key Is Stuck - how to repair stuck keyboard keys
Most of the shift key got stuck in the keyboard. If shift keyon any other keyboard key does not work or is stuck in the down position, you may try to remove it with a CPU "chip puller" tool. These simple "L" shaped tools are great at pulling out keys. Once you've pulled out the stuck key, you can try to stretch the spring to "reanimate" its action.

Computer Isn't Taking Inputs From Keyboard

1. Is keyboard connected to computer? Ensure that the keyboard is plugged into the keyboard jack and not into the mouse jack. If the keyboard was unplugged, plug it back in and reboot the computer.

2. If the keyboard still doesn't work on boot-up, power down the computer and try to borrow a friend’s known-good keyboard for troubleshooting. Plug the new keyboard up and boot up the computer. If the new keyboard works, the old keyboard is bad and needs to be replaced.

3. If the known-good keyboard doesn't work, check your BIOS to make sure it sees the
keyboard. It should say, "installed." If the BIOS recognizes the keyboard, then you probably have a bad keyboard port.

I Plugged Keyboard Into Mouse Port

1. Many mice and keyboards today use a PS/2 connector. If you plugged your keyboard into the mouse port (or vice versa), follow steps 2 and 3.

2. Shut down the computer and plug the keyboard into the keyboard port. The keyboard port is usually marked with a "keyboard" symbol. Plug the mouse into the mouse port (usually marked with a mouse symbol).

3. Reboot the computer; the keyboard should work now. If keyboard doesn't work, check your BIOS to make sure the BIOS recognizes the keyboard. You should see the words, "installed" or "enabled" under the keyboard.

4. If the BIOS recognizes the keyboard but it still doesn't work, you may have a bad keyboard port.

I Spilled a drink on my keyboard!

1. If you spill any liquid in the keyboard, turn it upside down ASAP. Drain all the water out of the keyboard, shaking it if necessary. If you've spilled water into the keyboard, just let it dry. You may use a hair dryer to dry out area under the keys (remember, too much heat and you could damage the electrical components).

2. If you've spilled a soda into the keyboard, completely rinse it in warm water. No soap please! You may use a hair dryer at this point or just let it dry for 2 days. Ensure the keyboard is perfectly DRY before you attempt to use it again. Don't plug a wet keyboard into electrical equipment. Think safety.

3. If the keyboard still doesn't work, replace the keyboard.

  14. This is an admirable work... You have a great article for computer users. Thanks for sharing!

  15. i cant use my back space key on the computer.

  16. i am having problems with my keyboard when i use nember keys on the top it does this !@#$%^&*() and when i use numberpad it does nothing what should i do

  17. laptop keyboard issue:
    when I type an "a" or an "s", a "d" will always follow. In fact, there is a pattern, often it's one "d" then the next time it's 2 "d's". So it looks like this:

    When I type adn ad or adn sd, ad d will adlwaddysd follow. In fadct, there isd ad padttern, often it'sd one d then the next time itsd two d'sd. I admd going craddzy! Cadn adnyone help?

  18. Nice stuff! I must say the article is really interesting but the comments are just mind blowing.

  19. Thank you for a superb resource blog. You are doing a great public service! Your step by step instructions are excellent. I look forward for your future posts.

  20. I can not hit the same key twice with out having to wait about 3 seconds. If I do it will not type it. Also, I can only scroll down once then I have to wait 3 seconds and it will scroll again but only one line.

  21. Further to "Computer Isn't Taking Inputs From Keyboard"

    1. Seek out and use the Onscreen keyboard as an emergency alternative. If there is no shortcut on screen, look for program


    2. You are likely to need to change the batteries. Before that it is worth checking if the keyboard is tuned to the wireless station.

    3. The wireless station (may be the wrong term) looks very like a mouse and is plugged into the computer next to the socket for the mouse. It has a button on the top very like the mouse’s scroll wheel. Let us call this button “A”. Near the button is a little red lamp.

    4. The keyboard has a tiny hole in its undersurface, within which is a tiny button – button “B”. The hole is difficult to spot. My keyboard in use in June 2010 has the hole covered by the folding right leg. My previous device had it exposed in the black undersurface about two inches down from the right leg.

    5. Tuning is done by pressing button B, with the point of a pencil or the tip of a knife, while pressing button A. The red lamp by button A will flash on a certain way; the flashing will change mode after about ten seconds, when the tuning will be complete.

    6. If this does not restore the keyboard service, the batteries must be replaced (3 x AA, at least heavy-duty and preferably ones that will hold their charge steadily to the end). After replacing the batteries, run para 5 again.

    Hope that is helpful.

  22. my keyboad keys on top. nos. 1234789 and 0 dont respond the rest of the keys are just fine. pls help.

  49. These are the typical reasons why a keyboard is not functioning so well. That's why in some companies they don't allow eating at your desk to avoid food debris from falling into the keyboard.

But running two antivirus programs on your computer – for example, running Microsoft windows 8 Security, which comes free with Windows, and then installing an extra antivirus program from a company such as McAfee or Norton – can cause conflicts on your computer. This can make your computer sluggish and at worst can cause computer crashes. If you have two different antivirus programs installed on your computer, make sure only one of them is active.
