Laptop users will encounter some keyboard problems more or less, such as laptop peripheral keyboard failure? In fact, keyboard failure is divided into many situations, the right medicine is the key. Let's take a look at the laptop peripheral keyboard failure solution that I have summarized for you. I hope to help you with the same situation.
First, the letter key will be displayed as a number
This is a relatively common case of laptop peripheral keyboard failure. This kind of keyboard failure is better solved. The numeric keypad and letter keys of the laptop keypad are integrated. Generally, the fn Numlk button can be used to switch smartly to small. Numeric keypad.
Second, the keyboard connection line breaks will cause the keyboard to intermittently fail
In the daily use of many users, it will be found that all the keyboard keys of the laptop peripheral are invalid, and the keyboard status indicator is extinguished at the same time as the button fails. After the user moves the keyboard, or restarts, the keyboard can resume work. The main reason why this keyboard can not be used is that the keyboard connection line is repeatedly bent or aged, causing the internal connection line to break and the virtual connection. If the player has strong hands-on ability, he can try to replace the keyboard connection line to solve the problem.
Third, the main control failure causes the serial key to be used
During the user's use, you will also encounter the phenomenon that the serial key cannot be used. It is shown that after the user presses a button, the input reaction of other buttons of the button appears. For example, after pressing the "A" button, the "B" letter appears, which is caused by a problem with the code library inside the keyboard master chip. Manufacturers can repair the serial key by rewriting the firmware. Ordinary users cannot repair it themselves. If the malfunctioning keyboard is still in the warranty period, it can be sent to the maintenance point for repair and replacement. If it is over-guaranteed, it can only be re-purchased.
The above is all about the failure of the laptop peripheral keyboard, I hope to help friends in need.
