The reason why the notebook keyboard can't print letters
Input method problem:
Now many people use the input method of windows system less, because although it is stable, the input efficiency is really low. So all kinds of new input methods are downloaded and installed in the computer, or other software is installed, causing conflicts between each other. Finally, the system is unstable and the input method crashes from time to time. It is recommended not to install multiple input methods with the same function.
Notebook keyboard failure:
At this time, you unplug the laptop battery and power adapter, and then plug it in again. All the above methods have been tried, but no word can be typed. It is estimated that there is a hardware failure in your laptop keyboard, such as water, key dropping, foreign matter entering, etc., which causes the circuit inside the notebook keyboard to be short circuited and open circuit. In this case, the keyboard will not be able to type. Just send it to the notebook repair point or after-sales service to deal with it better.
FN function key:
FN key is not used as input function in notebook computer. It is a pure combination key like Ctrl key. The combination of FN key and other keys can be directly supported by BIOS or software level. Many people who are not familiar with the notebook keyboard will encounter this situation. In fact, as long as you press and hold the FN key and numlk key at the same time, you can solve the problem of typing out numbers.
What should I do if I can't type letters on my laptop keyboard
The first reason is that the input method of notebook cannot be switched
1. Use the right mouse button to click the input method in the lower right corner of the desktop, and then select the setting option in the pop-up menu.
2. In the pop-up interface, we can select the input method that is not needed, then click delete, and then click OK to exit.
The second reason is that some of the letters are numbers, so they can't be typed
1. FN + NumLock switching method
We first press and hold the [FN key] (the FN key is usually in the lower left corner of the keyboard), and then press [num LK] (Num LK is generally in the upper right corner, above the F11 key, of course, different notebook locations are different). We can press these two combination keys to change letters into numbers, which is also the most commonly used method.
2. Screen keyboard switching method
In the above method 1, if your notebook can't switch from letter to number, there will be one problem with your keyboard keys and the other is the problem of software compatibility. At this time, we have to use another method to change letters into numbers on the notebook keyboard. The specific steps are as follows:
Click the [start] menu, then select [program], then select [accessories], and then select [Select auxiliary tools], find [screen keyboard], enter the screen keyboard settings, there is a [NLK key] in the small keyboard area of the screen keyboard, click this key, so as to realize the switching of notebook keyboard letters into numbers.
The third reason is that the notebook keyboard is out of order
1. First of all, it may be caused by careless operation of users. Hardware problems include the fact that the number keys and letter keys of the laptop keyboard are integrated, and you can switch to the small number keyboard intelligently by pressing the FN numlk key. Sometimes it's the reason that we press the alphabetic keys and turn into numbers. All those who buy notebooks look at the instructions.
2. Of course, this mistake will be solved in a moment, but if it still doesn't work, it may be that the keys are out of order. Sometimes, when we press the keyboard, there will be a lot of messy letters or numbers. That may be the reason that one of the keys was pressed down and didn't pop up. In this way, the keyboard was checked and ruled out one by one.
3. Try to change the keyboard driver by modifying the notebook keyboard driver. Click 'my computer' - select 'device manager' to find the 'keyboard' option. Usually, the default keyboard driver is' standard 101 / 102 key or Microsoft natural PS / 2 keyboard '. This is the Microsoft natural PS / 2 keyboard. Right click on the keyboard driver. Select the 'update driver' option, and the hardware update wizard will appear. Select 'install from list or specified location (Advanced)', click 'next', and select 'do not search, select the driver you want to install'.
Click next to go to the select device drivers to install for this hardware page, remove the small check box before show compatible hardware. Select 'Japanese PS / 2 keyboard (106 / 109 key)' in the 'standard keyboard model' column, click 'next', and 'update driver warning' will pop up. Select 'yes'. Click Yes in the confirm device installation window to complete the hardware update wizard operation. Then restart the computer.
4. Modify the registry, click 'start' -'run ', type' regedit ', open the registry, and find' HKEY 'in the pop-up registry editor_ LOCAL_ Machine systemcontrolset001controlkeyboard layouts'after careful examination, we will find that the simplified Chinese input methods ending in '0804' are all Chinese input methods. Open 'e00e0804', and you can see that there is a 'layout file' subkey in the right subkey. Double click to open the item, and the 'layout file' in 'numerical data' will be displayed kbdus.dll 'change to' kbdjpn.dll 'OK'. We can change 'layout file' to 'layout file' in all subitems ending with '0804' kbdjpn.dll According to their commonly used input method. Then restart the computer!
5. If all the above operations can't be repaired, it may be that the laptop keyboard is completely broken, so it will be necessary to replace the keyboard, which is expensive and troublesome. We can buy a desktop keyboard, through the USB interface to connect the notebook to operate.
