Computer keyboard number key failure how to do

　　Case Practice One:

User problem: My computer can not use the keyboard on the right side of the small number of key areas, "NumLock" light is bright, a few days ago is good, I did not move anywhere. What's the problem, please?

Best answer: If you are using windows2000/xp words, may be due to the start of the mouse button function, the small numeric keypad is used to control the mouse pointer, lost the input function. Select control panel → accessibility options → mouse, and then remove "Use mouse button".

　　Case Practice Two:

In some cases, computer users found that the keyboard keypad 0~9 can not be used, click No response, Subtraction button can still be used, encountered this problem do not worry, that is because the keyboard keypad number keys are locked.

Now I turn on the number key, which is as follows:

--"Press the SHIFT key 5 times or press Shift+ctrl+alt

--the "sticky key" in the jump to select "Settings"

--it will jump out of accessibility options and select the Mouse tab.

--"Use the mouse button" before the check to remove

--click on "Apply" "OK"

With this setting, the numeric keys on our keypad can be used.

Perhaps some computer users do not know, keypad numeric keys can be used as a mouse, the method is exactly the opposite of the operation above.

If you use the keypad key when the mouse, as long as the "Use the mouse button" in front of the hook on it.

At this point "8" represents the Move up the button, "2" to move down the button, "5" for the return button and so on!
