If it is the use of a sudden notebook keyboard failure, this time you can try an external keyboard, to find out whether the keyboard hardware problems. If the outside

The keyboard can be used, the initial judgment is the problem of the notebook keyboard.

Then you can try to reboot the computer to troubleshoot the reason for the keyboard failure is software or system problems, if the keyboard input after the reboot

Still have the problem, can preliminary judgment is the keyboard problem, at this time try to give the keyboard to clean up the dust and sundry way, to eliminate is because of the keyboard interference caused by

Keyboard failure, use a brush or suction balloon, cleaning and blowing way to try, whether it can solve the problem.
The above methods are tried, the keyboard can not be used in the case, the warranty period needs to find repair points, warranty period passed, need to find a professional help solve

The problem, the general may cause is the circuit board or conductive plastic has dirt or the welding place appears loose and so on signal transmission has the question, in short constructs

It is better to discuss the non professional maintenance or direct warranty.

If it is a boot, it found that keyboard failure, then directly from the hardware to find reasons, in cleaning up dirt and dust does not work in the case, can only repair

。

If the above method still can not solve the reference

The first keyboard input function is switched notebook keyboard typing out number:

This situation many of the laptop keyboard is not familiar with most people will encounter, when in fact, as long as you hold down the FN key and NUMLK keys to the two shortcuts can

To solve the problem of typing out numbers, the notes on the FN function keys for different notebooks see the second half of the answer.

Second input method out of question:

Now many people are less using the Windows system with the input method, because although stable, but the input efficiency is really low. So all of the downloads

The kind of trendy input method installed in the computer, or installed other software to create conflict between the end, resulting in system instability, input method collapse

The phenomenon of collapse occurs frequently.
The use of the notebook installed Sogou Pinyin Input method sometimes will be stuck in the notebook keyboard can not play the illusion of words. It may take a while to wait for the key

Disk can be typed, or restart the computer.

It is impossible to get word out, it may be the problem. Then you unplug the laptop battery and the power adapter and plug it in and try again.
The above methods have tried or can not be typed, it is estimated that your notebook keyboard has a hardware failure, such as water, drop keys, into foreign bodies and other causes

Notebook keyboard inside the line appears short-circuit, circuit breakers and other phenomena, this situation the keyboard is naturally can not hit the word. Send it to a laptop repair point or to a post-sale place.

Come on, Daniel.

ABOUT FN function keys

The FN key does not function as input in the notebook computer, it is the same as the CTRL key, the combination of the FN key and the other keys can be directly

Get BIOS support (this is the practice of most brands), or it can be software level (such as Sony's approach), of course, now most of the form is mixed

, which means that some key combinations are directly supported by BIOS in any environment, and some key combinations require additional software in the operating system.

Support to take effect.
