Instructions to repair the keys that do not work on a computer
Whether your keyboard accidentally got wet or you’re experiencing issues where letters pressed aren’t recognized, you can appeal to options like performing circuit repair if you’ve already tried everything and nothing works. For this, you have to be cautious so follow each instruction to the letter.
The first thing is that you find the following materials: a digital multimeter, blade and groove screwdriver, cleaning liquid for electronic elements, cloth or cotton, graphite pencil. When you have everything, you have to proceed to open your keyboard with the help of both screwdrivers in order to remove the cover.
Next, you are going to remove the membrane that covers the keyboard and focus your attention on the part that has the printed circuit. Now, you are going to clean it with the liquid that we mentioned above and wait for it to dry. Next, you should look at the circuit to determine which segments are not working as they should.
When you do this, you will proceed to use the multimeter by placing it on one of the nodes of the keyboard to measure its resistance. If you perceive any failure when doing this, you are going to repair the segment that is damaged with the graphite pencil and the fine brush, passing it over the surface with great care.
How to verify that the procedure was successful
For this, you are going to use the multimeter again, placing it so that it measures the resistance in “Ohm” so that you can observe the places that have a good electrical flow , so what you should pay attention to is that the result is as close to zero.
In this way, you will be able to check the areas that have greater continuity, being that, if any has a value greater than 1, it is possible that something is wrong, since the ideal is that the values are close to 0. Before To carry out this process, it is of vital importance that the keyboard is completely dry to avoid inconveniences that may arise.
Finally, you have to reassemble the keyboard, placing its respective membrane and connecting it to the computer to verify that all the keys work properly. In any case, if you feel afraid of doing all of the above, you can opt for the services of a professional technician in case you have any doubts.
Practical tips to avoid keyboard problems
For the life of your keyboard to be long, you must prevent damage and the best way to do this is through basic care, not only of the keyboard but of the PC in general. One of the main recommendations that we will give you is that you avoid, as far as possible, placing your keyboard in places that have a higher concentration of dust. If you have a laptop, you can use a PC fan to keep it from overheating.
Likewise, it is important that the keyboard is away from places with high humidity. In the event that water has been spilled on it, you have to disconnect it and clean the area very carefully to later check for serious damage. It should be noted that if at any time you also have problems with a gaming mouse , you can disassemble it and clean it to solve the
