The keyboard is a very simple and when component breaks down, the best thing you can do is buy another, because its price is usually pretty cheap. Often not worth fixing it, unless it's something as simple as for example a locked key. Here are some basic procedures that can be performed before going to the store to buy a new keyboard are given.
When we detect a problem with the keyboard, always remember to check first the most obvious, as with any procedure.
The keyboard stops responding
The first thing you should do if your keyboard stopped working completely, you restart the computer. This sometimes fixes the problem because the first time the computer boot, did not start properly.
If this does not work, look behind the system CPU, where all the connections, and see if the keyboard cable is fully connected. Verify that you are not connected to the mouse input instead of yours. This happens more often than we think. You can also turn off the computer, and remove the connection cable to see if the pins are in good condition. Many times a simple broken or bent pins can cause us such problems.
If this did not work, make sure to connect another keyboard and restart your computer. If the other keyboard works, replace the old one.
Keyboard error checking in Windows
If the new keyboard also fails you check the conflicts that play on your operating system. This you can find it by clicking right button on My Computer and selecting Properties, Manage, and finally "Device Manager", and in Windows 98 and Me you can check Start> Settings> Control Panel> Device Manager.

This makes them come loose cables internally, or connector emerges inside the same. The symptom is that the keyboard stops working, or wrong characters appear or fails keyboard at startup.
