A person who suddenly finds out that the keyboard on the computer has stopped working , few envy. And, as often happens, such troubles most often happen exactly when the reports are “burned”, a diploma project is completed, during the battle for the fate of the world in another computer game, etc.
On the other hand, the question “why the keyboard does not work on the computer” is not asked very often, since with the beginning of the “USB era” many “childhood diseases” in this area of computing devices are in the past. In light of this, a keyboard breakdown is a reason for a kind of pride in one's “luck”.Connection

Not surprisingly, this is followed by the question "why does the keyboard on the computer not work." Thus, with frequent connection, the plug wears out and needs to be replaced. Secondly, sometimes when a device is hot swapped, it crashes, so this feature should not be abused. To check the contacts you need to turn off the computer, disconnect the keyboard plug and carefully reconnect it, gently swaying in the connector. Sometimes the contacts can be returned with the needle to the previous spring state.

The solution is similar to the above. And, of course, do not forget that the malfunction can be in the connector itself: for verification, you need to connect the plug to another USB port.Software crash
