Situation one, the notebook itself keyboard failure

When we press the keyboard, there are a lot of messy letters or numbers, so it is possible that one of the keys has been pressed down the reason for not bouncing up, we can also try to restart the computer to eliminate the reason for keyboard failure is a software or system problems, if the restart after the keyboard input is still a problem, The initial judgment is the problem of the keyboard itself, it is not the problem of failure.

Method 1: Change the keyboard driver

1, the first mouse right click on the desktop "Computer" icon, select "Device Manager", in the Device Manager to find the keyboard options;

2, typically, the default keyboard driver is the standard 101/102 or Microsoft Natural PS/2 Keyboard, right-click the keyboard driver, and then select the Update Driver option, the Hardware Update Wizard appears, select Install from a list or a specified location (advanced), click Next, and select Do not search, choose the driver you want to install ";

We can change all the "0804" to the end of the subkey "Layout File" all changed to "Kbdjpn.dll", specifically according to their own commonly used input method to choose, and then restart the computer.

Because the Windows system comes with the input method of low efficiency, so many people will download their own input method installed on the computer, or installed other software to create conflicts between each other, resulting in system instability, input method crashes occur from occurrence. For example, installed Sogou, and installed search and other functions of the same input method, resulting in keyboard input unresponsive.
