Does the keyboard on the laptop not work?

Those whose professional activities are connected with the computer and traveling, very often the question arises why the keyboard on the laptop does not work . There may be several reasons for this (the battery in the villages, the battery is faulty, etc.), but among the most common ones are hit by liquid keys.

How to be in case of flooding the keyboard? Quickly turn off the laptop, disconnect the power and pull out the battery. Then we proceed to the washing of the keyboard and its drying during the day. After this time, we set it in place and check the work. If you reacted to flooding the keyboard promptly, then there is a chance to save it.

If all the same, the keyboard on the laptop does not work, it is dismantled and painted rotten tracks, only to do it can only those who understand it. So, to perform this type of repair, we need to take conductive glue, paint or varnish. You do not need to look for them on the shelves of specialized stores. Analogues of such liquids are in the auto parts stores - ask there for heating repairs on the rear window of the car. Before you remove the keyboard, make a photo or photocopy.

So, to understand why the keyboard does not work on the laptop, we begin to repair it. After removing the keyboard, which usually consists of 2 parts - a keypad and an elevator (sometimes there is also a spring-loaded element) with the help of a dental hook (if not, take a thin screwdriver for a clock or a similar shape from a set of engineers), we begin to carefully remove Polyethylene board with tracks that are drawn on it. On old laptops to melt the plastic edging on the back of the keyboard may need a soldering iron or a hair dryer, the first temperature should be regulated. When you later collect the keyboard, you will again need the help of these devices in order for the fasteners to melt, or instead of these mechanisms to use glue like "Supermoment".

So, we remove polyethylene cards to understand what really happened and why the keyboard does not work on the laptop. We do this very carefully, so that later there is no problem with their recovery. We use for careful separation of layers not only a hair dryer, but also a scalpel (or a clerical knife). Gently dividing the layers, we will see traces of spilled liquid once on the tracks. After washing and drying these places, we will find the damaged parts and we will check them with a tester. If the keyboard is thoroughly rinsed and dried, the corrosion is almost stopped. Therefore, the tester, in theory, should show resistance on all tracks closer to zero, most likely the figure will be 1-2 Ohm (in theory, it shows a short-circuit). Unfortunately, the track with damages generally can not ring or have quite a lot of resistance. If this happens, you need to put another on top of the rotten path. But if the putrefaction has reached the contact pad, the scalpel will help here, which will have to clean up the area next to the site and draw another path. When the glue dries (usually within one to one and a half hours), be sure to check the resistance. It remains only to collect the plastic bag and put it on a pallet of aluminum, and from above put carefully the parts with spring-loaded elements. We connect the keyboard and start the computer to check the operation of the keys. To do this, you can take either a "Keyboard test" (special program) or an ordinary notepad. So, the answer to your question: "What if the keyboard on the laptop does not work?" Given. The keys work fine, the laptop is in working order. Now it remains only to finish the collection of the keyboard. After turning off the computer and disconnecting the keyboard, we begin.

We have become acquainted with how to proceed, if the keyboard on the laptop does not work because of the fluid getting there, that is, with the actions that are to be performed for its resuscitation.

And if there was no flooding, and the keys, as the most vulnerable element of the laptop, ceased to function? What to do in this case? If some keys are out of order, for example, due to improper cleaning (using a simple vacuum cleaner) or due to the pampering of a child or an animal (cats, etc.), they should be cleaned with special soft brushes, napkins or compressed air. Of course, you can use vacuum cleaners that are manufactured by the industry especially for cleaning the keyboard, but they are usually not suitable for thorough cleaning of the rubber bands of buttons or contacts due to their low power.
