The computer keyboard is an input device that we often use, but we often encounter the situation that we can't type numbers. The following is the solution that I teach you that the computer keyboard can't type numbers. I hope I can help you!
First, eliminate the connection problem. You can check the connection between the keyboard and the computer to see if it is loose or disconnected. If it is loose, it needs to be plugged tightly. If it is broken, please connect it yourself or repair it.
If the light on the right keypad is not turned on, so it is impossible to input, press the NumLock key at the top left of the numeric keypad.
After pressing the num lock key, the leftmost indicator light at the top right of the keyboard will be on, and you should be able to enter at this time. As shown in the figure.
If you still can't input, you should consider the problem of key failure. You can try it. Try all the keys in the numeric keypad area to see if it works. If only a few of them cannot be entered, it indicates that there is a problem with the key. In this case, there is no other way but to find someone to repair or replace the keyboard.
If the whole keyboard cannot be input, the possible reason is that the keyboard has been seriously damaged. At this time, you have to consider replacing the keyboard. Pay attention to the interface when replacing the keyboard. The keyboard has PS2 interface and USB interface, which can be selected according to your own needs.
FN + NumLock switching method
We first press and hold [FN] (FN is usually in the lower left corner of the keyboard), and then press [num LK] (Num LK is generally in the upper right corner, above F11. Of course, different notebooks are located in different positions). We can press these two combination keys to change letters into numbers, which is also the most commonly used method.
Screen keyboard switching method
In the above method 1, if your notebook cannot switch from letters to numbers, there are problems with your keyboard keys and software compatibility. At this time, we have to use another method to switch from letters to numbers. The specific methods and steps are as follows.
Click the [start] menu, then select [program], then select [attachment], then select [Select auxiliary tool], find the [on-screen keyboard], enter the on-screen keyboard setting, and there is a [NLK key] in the keypad area of the on-screen keyboard. Click this key to switch from letters to numbers on the notebook keyboard.
