Repair of the "flooded" laptop keyboard

    With a diagnosis of “spilled soup,” they brought us a laptop that didn’t have a few keys working. Having carefully studied the bowels of the Internet, I came across several articles on the repair of keyboards and armed with a tool, I began to restore it.




    First you need to remove the keyboard from the laptop, and then remove all the keys and rockers from it.



    I will not describe the process of removal and installation for the millionth time since it is described in more detail here .



    After all the excess is removed, the board itself will appear. It is glued to the metal case of the keyboard. When separating it from the metal, be careful not to tear it, as there is a chance to catch it on the rocker mounts.



    After I took off the board and the problems started. After re-reading all the articles on this topic, I found that in no way can the board be parsed further. Turning it in my hands for a while I found a way out, oddly enough, that no one had lit on the Internet. Namely: to cut off rubber caps on idle keys. A stationery knife is great for these purposes.
    Attention! When cutting the caps do not exert much effort, try to peel them off the plastic board. In the future, we will need them for reverse installation.





    After the necessary caps have been cut off, unprotected contacts will be visible, and we were looking for them. Gently wipe them and the rubber caps (inside) with an alcohol-containing liquid. And proceed to the collection process.



    The collection process is completely identical to the process of analysis, here it is only necessary to highlight the moment of the return of the rubber caps.
    They must be carefully glued, I did this:
    1) Squeezed out a small puddle of “Super Moment - gel” on a piece of paper
    2) Carefully trying not to cover up anything superfluous, glue the edge of the rubber cap with which he was attached earlier to the board with glue
    3) I applied it to circuit board

    After everything is in place we completely assemble the keyboard in the reverse order. If this method does not suit you, try this one . And if you have damaged tracks on the board, then this one .

    I hope that this will be useful to someone. Thanks for attention!
