How to unlock the keyboard and unlock the computer keyboard?

1, on the rightmost side of the top row of the keyboard, as the name implies, its function is to lock/unlock the keyboard, which is an on-off key. Press this key once to lock the keyboard. At this time, press any key on the keyboard except this key, and the machine will not respond. When you press this key again, the keyboard will be unlocked.

2. If you press the "Numlock" key and press the "Numlock" key again with an external keyboard, it will return to normal. If you haven't received an external keyboard recently, you can find the "Fn" key in the computer keyboard and then find the "F8" key, because the second function of this key is the function of the "Numlock" key, and pressing the "Fn" and "Numlock" keys at the same time can unlock the keyboard numeric keys.
