Take Lenovo G40-70 and Win10 systems for example. When the computer keyboard is locked, it should be divided into the following situations:
1. If only the numeric keys of the keyboard are locked, click the "Num Lock" key to unlock it.
2. If the entire keyboard is locked, you can press and hold Fn+keyboard lock to unlock it. The keyboard lock is usually between F1-F12. There is a lock icon. If there is no icon, it is likely to be F11 or F12. Try several times.
3. If an external keyboard is used, check whether the "Num Lock" key on the upper right corner of the external keyboard is locked. Press the "Num Lock" key on the external keyboard again to open the laptop keyboard lock.
The computer keyboard cannot type. In addition to the reason that the keyboard is locked, there may be a problem with the input method or the computer system. You can uninstall and reinstall the input method or restart the computer to solve the problem.
This answer applies to most Lenovo computers.
