Troubleshooting Keyboard Problems

If the computer keyboard is not working at all, you should check its connections to the CPU cabinet. Locate the back of the cabinet where the keyboard is plugged in, remove the plug from the slot, and reinsert it, and then check if it works. If it is still not working, restart the PC and check. You can check the functioning of your keyboard or PS/2 (or USB port) by connecting the keyboard to another desktop computer, or using another keyboard on your system.

If you notice there are some keys on the keyboard that are hard to press or not working, there can be possibilities of dust and debris accumulated in there. You then need to clean the debris off the keyboard by turning it upside down and shaking it or tapping it from above. You can even use a vacuum cleaner for taking the dirt off the keyboard. In order to prevent the keyboard from attracting dust, you can use a ready-made keyboard cover or simply make one at home by using a plastic sheet.

If some character keys on the keyboard do not work even after cleaning the keyboard, you may have to replace those particular keys. This problem may be experienced mostly on frequently used keys. If some kind of liquid falls on the keyboard, immediately disconnect the keyboard from its cabinet port. Turn it upside down and keep it for drying in the same position for a while under the fan or in sunlight. Check the working of the keyboard by connecting it back again only after you are sure that its completely dry.

Some keys on the keyboard might not even function due to the device being in a cold room for a considerable period of time or not used for a while. If you think this can be the reason for the keyboard not functioning, you should use the keyboard for some minutes. Check if it works, after typing few sentences in the notepad application.

If the keyboard still does not work, updating the respective drivers may solve the problem. For updating the drivers on Windows Vista, go via Start->Control Panel->Hardware and Sounds-> Keyboard->Hardware->Properties->General->Change Settings->Driver->Update Driver. Check if the keyboard functions after the drivers have been updated. Driver updation is a good method of getting rid of a keyboard problem. Wrong characters issue can be rectified by changing the settings for the input language and the keyboard layout.
