My classmate’s Lenovo laptop reinstalled system, and then he found that the num keyboard was locked, besides, it couldn’t be unlocked by pressing NumLock key.

JoyToKey is a famous software simulating keyboard by game handles. Without installation, config files are saved under the root directory of the software, which means settled key simulation on one computer is applied on another one. Then I opened JoyToKey, and set the NumLock key on my laptop as one key on handle, and copy the software to another laptop with my U disk, at the same time, I connected my game handle (USB is better) on the laptop, opened JoyToKey, and pressed the key simulated the NumLock key on the handle, well, it succeeded!
2. Unlock by osk system command
“Start”—“Run” and keyed osk, click OK, and system screen keyboard would show up. The nlk key enclosured by a red frame is the NumLock key we are looking for. Just click with your mouse, then it’s unlocked! But don’t crow over, there’s still another problem! O and K, the two letter keys are locked initially! That means you
