Wrong laptop keyboard input, all letters are converted into numbers

I used a notebook, which is just happening. The keyboard input in my notebook is out of order, and all the letters are converted into numbers. I thought it was a computer problem at first, and I restarted it three times.

After studying for a while, I found that this is not a problem because I accidentally started the laptop keypad. If you do not dare to enjoy the solution exclusively, we will share the solution with netizens on the IT College Site.

Solution:

Press the FN key (lower-left corner) and the numeric lock key (numlock key in the upper-right corner) at the same time to turn off the numeric keypad. Note that the numeric indicator must be switched off.

This is because the laptop keyboard is smaller than the desktop keyboard, it is less than the desktop's small digital keyboard area on the right, so the notebook makes this Part a letter area. Note that the keys on the right of the letter area are in two colors. Use the FN function key and the number lock key to control whether the above words are still below.

It seems that the user manual of the notebook still needs to be carefully studied. Haha.
