The computer keyboard suddenly cannot be restored by typing in the following ways:
1, Fn+W is suitable for most models, Apple can press Fn+win.
2, Fn + NUMlock, if there is no NUMlock key, you can try to press Fn + Insert.
3. The Alt key may be stuck or malfunctioning, and you need to check the keys one by one.
4. Reinstall the keyboard program.
Computers are arguably the most inseparable tool in our work, but if the computer keyboard suddenly can't type, it will affect our work. So which key do you have to press to restore keyboard use? Let's talk in detail about which key to press to restore when the computer keyboard suddenly can't type.
1, you can first try to press the shortcut key Fn + W, the shortcut key is suitable for most models, if you are using the Apple series, you can. Press the shortcut key Fn+Win to switch back, some Win8 system models can try to press the shortcut key Ctrl+Fn+ Alt+W.
2, if the above combination of keys still does not work, you can try the Fn + Numlk key again, because sometimes we may press too fast, without paying attention to the case of the switch keypad. Because some computers do not have the "NUMlock" key, you need to press the Fn+Insert key at this time.
3, if the keys are not working, we have to consider whether it is possible that the Alt key is stuck, under normal circumstances, when the Alt is pressed, the computer keyboard can not type. So we need to check the keystrokes.
4, confirmed that the keyboard is no problem, and the keyboard is still unable to type, we have to consider whether it is a keyboard driver problem. We can find "Device Manager" in Computer Management, then find the "Keyboard" option, click on to view the keyboard driver, try reinstalling.
