HOw to Clean your keyobard effectively

Keyboard cleaningIf you're trying to clean a laptop keyboard see document CH000780 for additional help and information. All of the below information applies to standard desktop computer keyboards.
Why? Dirt, dust and hair can build up causing the keyboard to not function properly.
Procedure: Many people clean the keyboard by turning it upside down and shaking. A more effective method is to use compressed air. Compressed air is pressurized air contained in a can with a very long nozzle. Simply aim the air between the keys and blow away all of the dust and debris that has gathered there. A vacuum cleaner can also be used, but make sure the keyboard doesn't have loose "pop off" keys that could possibly be sucked up by the vacuum.
Why? If the keyboard has anything spilt into it (ie: pop, cola, Pepsi, Coke, beer, wine, coffee, milk, etc.), not taking the proper steps can cause the keyboard to be destroyed.
Procedure: Below are a few recommendations to help prevent a keyboard from becoming bad once a substance has been spilt within it.
If anything is spilt onto the keyboard turn the computer off immediately. Once the computer is turned off, quickly flip the keyboard over helping to prevent the substance from penetrating circuits. While the keyboard is upside down, shake the keyboard over a surface you do not mind getting wet or that can be cleaned up later. While still upside down, use a cloth to help clean out what can be reached. After you you have cleaned the keyboard to the best of your ability leave the keyboard upside down for at least one night allowing it to dry.
If a keyboard does not work after trying it again later it is recommended that it be replaced. If the keyboard works but some of the keys are sticky or cannot be pressed in you can attempt to do additional cleaning in attempt to resolve the issue. Unfortunately many times when any sticky substance such as a non-diet pop is spilt directly onto the keyboard it's usually a loss unless you plan on spending dozens of hours attempting to clean each key.
Why? A keyboard that is used by multiple people, such as students or different employees, may need to be disinfected to help the spread of germs.
Procedure: Turn off the computer. Spray a disinfectant onto a cloth or damp a cloth with alcohol and rub each of the keys on the keyboard. As mentioned in our general cleaning tips, never spray any type of liquid onto the keyboard.

Spilled some red wine in my Toshiba Satellie L640 and now some of the keys stick or don't work so I would like to clean it. 1. How does one do this? 2. Is it a bad idea to do this? I'd rather not take it in to a PC repair place.


Hi.

You can try cleaning the keyboard but the keyboard has to be removed first before you attempt to clean it. That hopefully will work, however please be aware that if the wine has gotten between the keyboard membrane then it could cause the keyboard to type other characters not assigned to them or others as well as their own when you reinstall the keyboard.

To clean the keyboard first we have to remove it. Turn the laptop off and close the lid, remove any AC power that's connected. Turn the laptop over and then take out the battery.
In the battery compartment remove the 2 screws holding the keyboard bezel down that are circled in the picture below. (the keyboard bezel is thin piece of plastic that runs the length of the laptop above the keyboard)

When the screws are removed turn the laptop back over, open the lid and carefully lift up the keyboard bezel and remove it from the laptop like in the picture below.

Next you have revmove the three screws securing the keyboard in place like in next picture.

Lift up the top side of the keyboard and rest it on the palm rest/touchpad. Be very careful as the keyboard is still connected to the motherboard like in this picture below.

Now you have to remove the keyboard. In order to remove the keyboard you'll have to unlock the connector and release the cable.
Look at the next picture and lift up the right side of the locking tab so it opens up at a 90 degree angle as shown and carefully pull away the ribbon cable

Lift the keyboard away from the laptop and then get a clean, warm, damp cloth and start to wipe the top of the keyboard. Don't try to remove the keys as you can damage the cradles and also they are very hard to put back on.
Keep on rinsing the cloth with clean warm water and wring it out a bit. Keep on repeating this until the keys release and become springy again.
Once you are happy with keyboard just reinstall the keyboard by reversing the steps above.

When you have re-assembled the laptop turn it on and open a notepad or text document and see if the keyboard is typing all the correct characters for the printed symbol. If some are not working or are typing multiple characterst then you will need to replace the keyboard. Click on the blue link below for an idea.

Hope this helps, good luck.

Keyboard


No keys on my keyboard work. Cause: This issue is often caused by either a bad keyboard, bad interface board, and/or bad motherboard.
Answer: Disconnect the keyboard from the computer and connect another known working keyboard to it. If this is a PS/2 keyboard and connecting multiple keyboards or a known working keyboard to the computer PS/2 port does not work unfortunately it's likely that the PS/2 port is bad. Because this port is part of the motherboard this will require that you replace the motherboard. Alternatively if replacing the motherboard is too costly or not an effective solution you could also consider using a USB keyboard if USB ports are available on the computer.

Not all keys on keyboard work.

Reference number: CH000305
Not all keys on keyboard work. Issue: Not all keys on keyboard work.
Cause: This issue is often caused by a bad keyboard or software preventing these keys to be pressed.
Additional information: This document contains information about troubleshooting a keyboard that has some functioning keys. If no key on the keyboard is working see document CH000955.
Solution: Verify that the key is not working in more than one application. It is possible that some keys may not be used in all programs. This generally always applies to the Function keys F1 through F12. If not all keys are working in all programs and you have Windows, attempt to boot the computer to a MS-DOS prompt or safe mode and test the keyboard in DOS. Information about getting into safe mode can be found on document CHSFAFE and information on how to boot to DOS can be found on document CHDOS. If it appears that a substance has been spilt into the computer, please review document CH000303. If all above suggestions have been completed or if you are not running Windows, it is likely that the keyboard and/or keys are bad and it is recommended that the keyboard be replaced with a new one.
