Failure of computer keyboard keys, "which we often encounter the problem. This phenomenon usually occurs because the circuit board or conductive plastic on the dirt, making between the two can not be properly connected. Other factors may also be, for example: keyboard plug is damaged, circuit problems, damage to the motherboard, CPU is not working properly, etc., but not the main reason so we can work only for descaling.
The steps are as follows:
1. Open the keyboard. Note that when you open the keyboard, be sure to button face(that is, we are operating side) down, board up, or conductive plastic on each key wouldhave come off, to repair your trouble.
2. Open circuit boards, circuit boards are generally made of soft plastic film, is inscribed with a key cable, preferably with a concentration of alcohol in 97% cotton and gently scrub two times in the circuit board. Key part of the line for the failure to take care of several times more
3. View key part of the conductive plastic failure, if the above accumulated a lot of dirt, the same use of alcohol scrub. Assuming conductive plastic is damaged, then I suggest you can not key on the conductive plastic used for the damaged part, although this"shattering" of the initiative can not play all the keyboard functions, but the most can at least extend the life of frequently used keys.
4. Corner of the keyboard clear of dirt, brush tool available, small brush, etc., but note that some of the action should be gentle.
5. Check whether the module is soldered or welded sealing off, if you make the electricsoldering iron, you can repair welding work. Of course, this step applies only to makefriends electric soldering iron, do not use a friend, please skip this step
6. Install a good keyboard. It should be noted here that we have to wait after thealcohol to evaporate.
