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. So we thought that the NumLock key is broken. As the laptop num keys are together with some letter keys, so when they are locked, if you want to type the letters, and it prints numbers, so what would you do? Install another system? Too troublesome, besides, we cannot sure whether the new system locks Numlock key by default or not. So I beat my brains and found two methods to solve this problem easily.
1. Unlock by JoyToKey software
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
