Case 1, the notebook itself is out of keyboard
When we press the keyboard, there are a lot of messy letters or numbers, then it is very likely that one of the keys has been pressed and not played. The reason for coming up, we can also try to eliminate the cause of the keyboard failure by software restart, whether it is a software or system problem. If there is still a problem with the keyboard input after restarting, it can be judged that the keyboard itself is a problem, it is not a malfunction. .
Method 1: Change the keyboard driver
1. First right click on the “Computer” icon on the desktop and select “Device Manager” to pop up the device manager. Find the keyboard option;
2. Normally the default keyboard driver is “Standard 101/102 key or Microsoft natural PS/2 keyboard”, right click on the keyboard driver, then select “Update Driver” ” option, the hardware update wizard will appear, select “ install from the list or specified location (advanced) & rdquo;, click & ldquo; next & rdquo;, select & ldquo; do not search, choose the driver to install yourself rdquo;;
3, then click “Next”Enter“Select the device driver to be installed for this hardware" uncheck the "display compatible hardware", in “standard keyboard model&rdquo In the column, select “Japanese PS/2 Keyboard (106/109 Key)”;
4. Click “Next”, pop-up "Update Driver Warning", select “ Yes & rdquo;, “ Confirmation Standby installation & rdquo; window continue to click "Yes" to complete the hardware update wizard operation. Then restart your computer.
Method 2: Modify the Registry
1. Click "Start”-“Run”, type “regedit” to open the registry;
2 In the pop-up registry editor, find "HKEY_LOCAL_MACHINESYSTEMControlSet001ControlKeyboard Layouts"; a closer check will find that the end of the "Simplified Chinese input method";
3, open “E00E0804”, you can see In the right sub-item, there is a “Layout File” sub-item. Double-click to open the item, and change the "kbdus.dll” in "value data" in "kbdjpn.dll”,"determine" . We can change all “Layout File” in the sub-items ending with “0804” to “kbdjpn.dll”, depending on your usual input method, and then restart the computer.
Case 2, input method problems
Because the input method of the windows system has low input efficiency, many people will download the input method to install on the computer, or install other The software causes conflicts with each other, and finally the system is unstable and the input method crashes. For example, the Sogou is installed, and the input method of the same function such as Soso is installed, which causes the keyboard input to be unresponsive.
Solution: Right click on the input method in the lower right corner of the desktop, and then select the setting option in the pop-up menu. In the pop-up interface, we select the input method that is not needed, and then click delete.
Case 3, some letters are numbers, which can't make the notebook keyboard.
The notebook keyboard is different in design from the desktop keyboard, so many people estimate that when they suddenly use it. Will not be used to it.
