1. Cause of failure: The keyboard keys are out of order, which is generally due to dirt on the circuit board or conductive plastic, which makes it impossible to connect the two normally. Other factors are also possible, such as:

Broken keyboard plugs, faulty wiring, damaged motherboards, CPU not working properly, etc., but not the main cause. Therefore, only descaling is required. 2. The steps of fault maintenance are as follows (note that the scissor foot keyboard is mainly used for notebooks as a super book keyboard, and do not disassemble it when the keyboard is modular for personal maintenance, otherwise it cannot be installed back):

1) Disassemble the keyboard. Note that when you open the keyboard, you must touch 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 wide circuit board, the circuit board is generally made of soft plastic film, engraved with key lines, with the best concentration of more than 97% alcohol cotton or more than 75% medical alcohol cotton gently scrubbed on the road board.

For the faulty part of the key, the wiring needs to be wiped several times. (3) Check the conductive plastic of the failed part of the key, if there is a lot of dirt accumulated on the upper area, also use alcohol to scrub. Assuming that the conductive plastic is damaged, it is recommended to replace the conductive plastic on the infrequently used keys with the damaged part, although this measure will not allow the keyboard to play all its functions, but the starting code 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 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) After installing the keyboard, there is one thing to note here, that is, it must wait for the alcohol to evaporate before proceeding.

Possible causes: 1. Computer program failure. Workaround:

It is recommended to restart the computer. 2. The keypad is locked. Workaround:

It is recommended to press the numlock button in the upper right corner, and then press the number key again to see if the number can be played out. 3. The keyboard is broken. Workaround:

It is recommended to get a new keyboard.

<> case that the numeric keypad of the computer cannot be used is handled as follows:

The number keys of the computer keyboard are out of order, and the overall number keys of the desktop secondary keyboard (numeric keypad) are not easy to use. Check to see if the Num Lock button is on.

The number keys on the computer are messed up, and the number keys above the main keyboard on the desktop are not easy to use. Check to see if the keys, shift, etc. are pressed.

If you can't use a notebook with your computer's numeric keypad, please look for the corresponding brand of key fn and the corresponding open function key combination.

1。Restart your computer!

2。Unplug the keyboard and plug it back in!

3。The "Num Lock" key above the keypad, press it down, and it is activated!

Fault 1: Some letters are typed out of numbers, resulting in inability to type.

In this case, the integration mode of the letter and numeric keypad was accidentally switched to the numeric mode, and at this time you will find that the letters on the right are typed out of numbers, in this case, the numeric keypad is turned on, and the solution is very simple, press the fn+num key combination to switch back.

Fault 2: Notebook input method switching.

No, or switch input methods.

It's stuck. There are often netizens who encounter the phenomenon of opening the browser, switching input methods and getting stuck, in fact, this phenomenon is a typical input method and input method or other applications.

Manifestations of conflict. Because the input method that comes with Windows is not very easy to use, many friends will choose to install Sogou.

Or search and other input methods,But it should be noted that most of the domestic Internet giants only care about their own interests,Do not think much about compatibility with some other competitive input method software,Therefore, if you install multiple popular input methods, it may cause conflicts between input methods,Resulting in frequent switching input methods in conflict。

Solution: Keep only one of the most suitable input methods for yourself, and uninstall some input methods that are not commonly used. Here's how to uninstall the deleted input method:

You can also go to the control panel.

Find the language and then the text and input language options, find the input method settings, and enter the following interface, you can delete some input methods that are not commonly used, as shown in the following figure:

Fault 3: The laptop keyboard is malfunctioning.

Notebook keyboard is actually more prone to failure, especially water or knocking for too long may also lead to damage to the notebook keyboard, generally the notebook keyboard is broken, some keys fail, for this kind of problem it is recommended that you use an external keyboard, because the notebook replacement keyboard is very expensive, so it is not recommended to replace, you can also use the system's own screen keyboard, the opening method is: start--program--accessories--auxiliary tools--screen keyboard, the effect after opening is as follows:

Notebook keyboard can not type basically on the above 3 situations, the method of troubleshooting is also relatively simple, the key is that we need to have such a way of thinking, I hope this article can be helpful to friends who encounter similar problems in the later stage, in fact, many computer fault solutions are the same ideas, first simple and then complex, with the help of the elimination method, try to use the troubleshooting method.

The computer keyboard you said 123 can be typed,The numbers behind can't be typed,Is it the above row of numbers or the numbers on the keypad,If it's the numbers on the keypad,It may be because of a problem with a block,You try to switch the input method。

You can check whether it is a problem caused by a computer virus to see if there is a problem with the system, detect the keyboard, you can change to another keyboard to try, or take this keyboard to try on other machines (except for notebooks), you can ask professionals to help you take a look.

It should be that your keyboard is broken, you can replace it with a new one.

The keyboard is broken. Generally, there is no maintenance value, and basically no one repairs it, so I buy it again for dozens of yuan.

This is caused by not opening the keypad, for desktops, just press numlock in the upper left corner of the keypad area.

For laptops, hold down fn on a non-full-size keyboard, and then press numlock. The same desktop with a full-size keyboard.

Keypad – for quick entry of numbers, etc., with the numlock key, you can switch between the cursor function and the numeric function.

In addition, notebooks now have keypads with numbers above and below the letters.

There's too much soot in the cracks of your keyboard... Causing a short circuit in part of the keyboard, you buckle the keyboard over and knock it, knock out the soot and float inside, and you can make it. My original keyboard was because I didn't pay attention to hygiene when smoking, and the soot fell too much into the keyboard, which was often not good, but it was good to knock the ash out.

In addition it is advised that smoking is harmful to health.

Is it that the keyboard is broken, or that the keyboard and the chassis are in poor contact.

It's bad! Try a different keyboard!

Mine is the same, just call the computer repairer to come

You can type one of the lines above.

If your keyboard gets water, so can the waterproof one.

Dear netizens:

A row of 1234789 number keys on the keyboard is pressed and it is not reflected, the indicator light on the keyboard is on, I have a solution, as described below:

Cause of failure: The reason why 1234789 cannot be used is that it is detected to be a fault caused by the circuit break.

I'm using a double delphinium keyboard, I've been using it for about 8 years, and now I'm taking double swiftlets as an example:

One. Wipe the surface of the keyboard clean with a soft cloth, two. Turn the keyboard over and press the keys down, use objects on both sides to support the keys in the air, and use a small driver to remove the back cover of the keyboard, three. Gently remove the soft plastic circuit board from the keyboard and wipe it clean with a soft cloth (do not use force to avoid damaging the circuit). Then, use a multimeter to measure section by section from the root of the button, find the break point, and then make a connection.

Six. Connection Method:

Go to the store department of the computer to buy conductive adhesive, (small specifications can be, more useless) use conductive adhesive according to the width of the line on the open position, troubleshooting.

If you can't buy conductive glue, you can also find a piece of wire to extract the thin copper wire inside, take its length according to the position of the line, and then prepare a short section of plastic tape to stick the copper wire on the tape, and then stick the copper wire with the tape tightly on the break point, troubleshooting

The keyboard is broken, and it is generally flooded.

Is it a notebook?,Is there a problem with the shortcut keys?。
