Notebook input letters into numbers

Friends who use laptops may often experience situations where a number appears on the screen when we enter letters on a notebook keyboard. What happens when this kind of "input letters into numbers" is happening, and how are we going to solve it?

In fact, the notebook keyboard to enter the letter variable number is because the notebook keyboard turned on the numeric keypad lock. The way to solve the letter change of the notebook keyboard is simple, we just turn off the digital keypad lock. The closing method is as follows:

Find the NUMLK key on the keyboard (generally blue, located in the upper right corner of the keyboard, on the F12 or around it), after you find it, press and hold the FN button in the lower left corner, and then click the NUMLK key. This way, the notebook keyboard to enter the letter variable number problem solved.

However, the FN key for some notebooks can only be used after the computer has installed the appropriate power management software, and pressing FN+NUMLK does not solve the problem of typing alphanumeric characters into the notebook keyboard. At this time, we need to go to the notebook manufacturer's website to download or from the notebook attached to the CD to install power management software, and then use FN+NUMLK to turn off the digital keypad lock.
