The keyboard of the laptop can t be typed

Hello. Happy Chinese New Year! The laptop keyboard is out of order, what to do.

Please refer to the Experience

Friend: Be sure to back up the registry before modifying the registry values

For details on how to back up the registry, please refer to the "Experience".

Workarounds for laptop keyboard malfunction:

1. Replace the document program test, create a new word or txt document, if the problem occurs in individual software, consider individual software problems.

2. Enter the safe mode of the system to test whether it can be used. If it can be used in safe mode, consider it a system or software issue.

3. Thoroughly disinfect the system.

4. If the above method test is invalid, backup important data to restore or format and reinstall the system.

5. The laptop keyboard is out of order, and the keyboard needs to be detected or replaced.

This phenomenon is generally due to dirt on the road board or conductive plastic, or because drinks, water and other things flow into the keyboard, so that the two cannot be connected normally. It is also possible that some keys cannot be used due to a breakpoint in the circuit board in the keyboard.

The steps to clean up the dirt are as follows:

1) Disassemble the keyboard. Note that when opening the keyboard, be sure to turn the button side (that is, the side we operate) down and the circuit board up, otherwise the conductive plastic on each key will fall off one after another, causing trouble for your repair.

2) Open the circuit board, the circuit board is generally made of soft plastic film, engraved with key lines, with a concentration of defeat shouted that it is best to use more than 97 alcohol cotton (more than 75 medical alcohol cotton can also be, because I have used it, but it is best to use high concentration of alcohol cotton) gently scrub the road board twice. Take care of the key failure part of the circuit several times.

3) Check the conductive plastic of the failed part of the button, and if there is a lot of dirt on the upper area, use alcohol to scrub it as well. Assuming that the conductive plastic is damaged, then the author suggests that you can replace the conductive plastic on the infrequently used keys to the damaged part, although this kind of "family dry talk about tearing down the east trillion wall to make up the west wall" can not make the keyboard play all the functions, but at least can extend the life of the commonly used keys.

4) Remove the dirt in the inner corners of the keyboard, tools can be brushes, small brushes, etc., but pay attention to the action should be gentle.

5) Check whether the soldering module has false soldering or desoldering, and if you can use an electric soldering iron, you can repair the soldering work. Of course, this step is only applicable to friends who can use an electric soldering iron, and friends who can't use it, please skip this step.

6) Install the keyboard. One thing to note here is that you must wait until the alcohol has evaporated.

What should I do if I can't type on my laptop keyboard? Let me tell you about it.

01 First of all, if the notebook keyboard can't be entered, if we have installed the Sogou input method, we can click on the keypad on the floating window of the Sogou input method with a laughing button;

02 The interface that pops up, we click on the soft keyboard;

03 In the pop-up interface, we can see a small keyboard, we can use this small keyboard to enter text first;

04 After that, we need to take our notebook to find a computer repair shop to repair our keyboard, generally the keyboard can not be entered, basically caused by the poor contact of the keyboard's cable.

You have the numeric keypad turned on. Because some keys have two characters on them, they can be used to switch between bending and brightening.

Method: Turn off the keypad, use the FN+NUMLOCK number lock key, first press and hold the "FN" key, and then press "NUM LK" to switch the keypad.

Extended Materials. What should I do if I can't type on my laptop keyboard.

2. After finding it, right-click it. After right-clicking, the settings bar of the mountain will appear, in the settings bar, pull the arrow of the mouse cover to the bottom, and click the mouse on the left mouse in the place of attributes.

3. After clicking on the properties, a control panel will appear, as shown in Figure 1 belowThen look at Figure 2, where I marked with the red arrow, and find "Device Manager".

4. Then, left-click to open the device manager, and the following figure appears.

5. In this device manager, we find the keyboard from top to bottom. Click on the small triangle in front of the keyboard first, and a sub-management will appear. Then click on the red line.

<>6. Finally, in the control panel that appears, first find "Driver", then click "Update Driver" below, and finally click "OK". (We mark on the diagram).
