The keyboard is one of the most fragile components of a laptop, subject to various external factors. In addition, after the matrix, this is the second component of the laptop, which breaks down most often.
If for a stationary computer the keyboard malfunction problem is easily solved by acquiring a new one, then in the case of a laptop, the problem is most often solved only by replacement.

- violation of the integrity of the conductive mechanisms;
- failure of the multicontroller;
- the appearance of rust on conductive plates;
