Troubleshooting an unusable computer keyboard

You don't always have to replace a keyboard when it is not working although the cost of it now is very inexpensive but why spend money when you don't have to.Simple problems can easily be fixed.

Here are a few symptoms:

A few keys don't work: 

• Remove the cap on the bad key and spray contact cleaner into the key well. Repeatedly depress the contact to clear it out. Don't use rubbing alcohol to clean the key because it will add residue to the contact.
• If this method of cleaning solves the problem, then clean the adjacent keys as well
• Turn the keyboard upside down and ban the key tops to dislodge debris 

The keyboard does not work at all: 

Troubleshooting keyboard

• Is the cable plugged in securely?
• Exchange the keyboard for known good one. If the problem is in the keyboard, if possible, swap the existing cable with a cable known to be good,perhaps from an old, discarded keyboard. Accomplish this task by removing the few screws that hold the keyboard case together, then unplugging the cable.Be careful as you work;don't allow the key caps to fall out!
• For a keyboard proven to be bad, if the problem is not the cable, discard the keyboard.
• If the problem is with the computer, consider the following;On the system board, the two chips that affect the keyboard functions are the keyboard chip and the ROM BIOS chip. You might choose to swap each of these chips on the system board. Otherwise the entire system board may have to be replaced

A major spill on the keyboard:

• For major spills on the keyboard, thoroughly rinse the keyboard in running water. Give the board about two days to dry. You can speed up the process if you set it out in the sun or in front of a fan.
