Soft method to solve the notebook keyboard input letter failure

Today, my friend called me and said that his notebook keyboard had a problem, it was used well, but I don’t know which key the child pressed, the button on the notebook became confused. When you press the U, I, O, etc. keys, the words are not letters, but become numbers 4, 5, and 6. When you press J, K, and L, they also become numbers 1, 2, and 3. Ask me if the keyboard is broken.

In fact, this problem is solved very well. This is caused by mistakenly opening the digital keypad of the laptop. Most laptops can solve this problem by pressing the FN key and the digital switch button on the keyboard, but now The keyboard layout of this book is not very uniform, so sometimes it can't solve the problem. I taught my friends a common way to turn off the numeric keypad. Just click “ Start /All Programs /Accessories /Accessibility /On-Screen Keyboard, you will definitely see the NLK button displayed in red after starting the on-screen keyboard, you can resume the input letter function with a click of the mouse.
