There are a few keys in the laptop that fail after cleaning the keyboard

It failed after cleaning, and I don't know which solution you used to clean it. The recommendations are as follows:

1. Connect an external keyboard to see if the problem is eliminated, if it is eliminated, it means that it is a keyboard problem, if not, it means that it is a system or motherboard problem.

2. Re-use anhydrous alcohol for a comprehensive cleaning, but the technique should be light.

3. Relink the cable between the keyboard and the motherboard, and see if the cable is broken.

4. Comprehensive anti-virus.

If none of the above methods work, the only way to do this is to replace the keyboard or motherboard.

First of all, take down the key that doesn't shine ... Blow the components below and look at the general no problem.

If it's not good yet, remove the entire keyboard to dry.

If it's not good, replace it.

About 100 or so.

It is recommended to go to after-sales. Don't tell him you got it while you're cleaning. Let's just say that the use of it fails.

Most of them will take it apart for you. And then if it's insurable. will give you a new keyboard.

If they think it's water ingress. You can go outside and order a keyboard. Probably between two hundred and three hundred.

Of course, it will be cheaper to have acquaintances. This is what you can usually get at a dealership**.

Judging from the failure of these keys, there should be a problem inside the keyboard, because the keys on a column like this longitudinally, the internal membrane should follow the same line, you can disassemble the keyboard to see if there is a short circuit in the process of wiring, whether the keyboard has been flooded, and whether the position of the gold finger is loose.

PS 2 keyboards are generally cheaper now, 20 yuan to 100 yuan, Logitech, Shuangfeiyan, BenQ can be considered, just go to the local electronic city to see.

Not really, right? Did water fall into the machine?

You remove the keyboard and see if there are any problems. Maybe the keyboard assembly comes off. Or maybe there's a problem with those buttons.

It is not excluded that the keyboard is already broken.

If it's really a broken keyboard, it will be hacked by JS.

Notebook keyboards cannot be washed with water, and can only be cleaned with a professional live cleaning agent.

The computer keyboard is one of the most commonly used computer input devices, and it is also the most frequently used device. Due to the high frequency of computer keyboard use, it is common for computer keyboard to malfunction during use. The solution after the computer keyboard fails is as follows.

There are generally two scenarios when a laptop keyboard fails

One, press the alphabet key to turn into a number. Many friends who know about laptops will know that the number keys and letter keys of the notebook keypad are integrated, and generally press the fnnumlk key to intelligently switch to the small numeric keypad. Some notebook brands may be different, you can refer to your own notebook instruction manual.

On the other hand, there is no response when pressed, or the keys are not displayed regularly. This is mostly a problem with the keyboard,You can try to clean up the notebook keyboard,Check each key,See if there are some keys pressed and not bounced,Resulting in the situation that pressing other keys is useless,In addition, if it is really the notebook that comes with the keyboard is damaged,You can replace it (but the cost is very expensive),Or buy a keyboard with an external interface is not also very good,And cheap。

1.In the first case, press the shortcut key FN+F1 or FN+F2 on the keyboard to enter BIOS mode, if you can't enter BIOS mode, and press the keyboard F12 and other keys are not responding, it means that the keyboard hardware is faulty, and you can only apply for after-sales maintenance.

2.In case 2, if you can enter the BIOS normally, it means that the probability of keyboard hardware failure is small, and it may be caused by abnormal or incompatible keyboard drivers

If the keyboard driver is abnormal, you can update the keyboard driver, 1. Find the Windows system in the beginning. 2. Open the control panel and select Hardware & Sound. 3. Click on the device and printer to select the notebook, and click on the hardware to find the keyboard.

Asking questions about 1 and 2, A is not good.

Workarounds for laptop key 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.

Is there only one failure, or are there many? Can the buttons be matched to the displayed things? It may be the cause of static electricity, remove the battery, press the power button a few times to release the static electricity, and then turn it on, and then go to repair it.

This is a common malfunction of keyboards, and some of the most frequently used letter keys are the most likely to have problems.

Keyboard replacement should be noted that the keyboard of the laptop can only be replaced as a whole, not a single key.

Reason for key failure: The key is dirty, the contact is not good, or the spring has lost its elasticity.

Solution: 1. You can open the keyboard by yourself, clean the inside of the keyboard with anhydrous alcohol (the part that is in contact with the keycaps under the failed keys), if there is a layer of transparent plastic film inside, please uncover it and then clean it.

2. If the desktop keyboard is not handled well, there is no need to worry, you can change to a new keyboard.

3, but for the keyboard of the notebook, if there is a problem, it is more troublesome, and if it cannot be repaired, you can think of using software to redefine some infrequently used keys to replace common keys. (One of the easiest ways to do this is to hold down the alt key and then enter the ASCII code of a commonly used key on the keypad, e.g. alt+68 is a capital "d").

The reason why the keyboard fails and cannot be used is that the keyboard itself is damaged, or the chip of the motherboard control keyboard is damaged, and there is also a situation where the system is a problem, and it will be okay to reinstall the system, and the notebook hardware doubts are answered.

Do you need a keyboard driver? I don't think so, I haven't heard of system problems causing those keys to fail. The reason for the failure of the general keyboard is what you call the impossible points, water, dust and foreign objects, **, the keys are used too frequently, etc., I think the hardware is the keyboard is very likely to have problems, you had better find a place to repair the notebook to help you test it.

It may be that the after-sales service center is not connected when it is wired, resulting in a bit of a loose keyboard interface, and it is best to use an external keyboard for the notebook, which is convenient for typing and protects the notebook keyboard.

You must go to the after-sales service, you just bought it not long after the warranty period is free to repair, do you want to wait for the warranty period to expire and then spend money to repair!!

Repair can be repaired, but you'd better go to a specialty store to repair, and individuals are easy to be deceived.

This can also happen if you have something dirty in your keyboard.

Buy an external keyboard urgently, go to ** buy a keyboard with the same model, remove the screws of the computer and install it, buy the same keyboard for only 50 yuan, you have to find maintenance for 200

Hello, in this case, it is recommended that you boot on and press F8 to enter safe mode to detect whether it is available.

If it is available, it is a software issue under the operating system.

If it is not available, it is generally a hard drive problem, and you need to contact after-sales service for professional handling.

The pad in the keyboard can't bounce up, remove these keys from the keyboard, and try to reset the pad.

It could also be a virus.

This situation.

If you're not in a hurry, buy a U-port keyboard. If you're in a hurry.

If the economic conditions allow, the factory will be repaired.

I'm using a nce notebook, and after reinstalling it, there are a few keys that don't work. Numeric key seven, as well as f1, f2, f8, f9, a few keys, are all good before reloading, and there is a problem after reloading. Seek help..

You see if you can type with a soft keyboard, and if you can type, it should be a hardware problem, see if there are any foreign objects under the keyboard. If it doesn't work, you'll have to reinstall it. It's better to change the system and reinstall it, or if it doesn't work, you can only send it to the maintenance point.

Two scenarios.

1. The card slot on the motherboard that links to the keyboard is damaged, it may be the wrong screw, it may be a fall, and the second system problem is opened.

Now let's reinstall the system.

If there is still such a problem.

Get it for after-sales repair.

It won't be expensive.

If you've changed the system, it's probably a problem with the system, not a hardware problem.

How to deal with laptop keyboard failure:

1. Boot the button, enter the BIOS, and check the BAI here to see if the keyboard is out of order. It also fails, then the du is the keyboard is broken.

2. If the BIOS does not malfunction and the operating system is abnormal, it is a system problem, and you can check whether the driver has dropped.

3. The notebook interface is bad or there is a problem with the motherboard.

4. If the control IC chip fails, you need to go to the maintenance center to deal with it 5. There is a problem with the computer system itself.

6. If the above methods cannot be solved, you need to go to the after-sales center for testing and replacement.

The solution to the failure of individual keys in the notebook is as follows:Find the causeThe failure of the keys is generally due to the defect of the internal circuit board of the computer keyboard, and the internal circuit board or conductive plastic of the keyboard is not clean and dusty for a long time, resulting in the circuit being unable to connect, resulting in the failure of some keys.

Cleaning Steps:1. Step 1: Clean the keyboard and clean up the dirt and dust inside.

2. Step 2: Buckle up the broken keycaps, see if the silicone inside is shifted, and take a small screwdriver to dial it back.

There is no way to repair the keyboard if it is broken, only to go to the after-sales service, if it is not given money during the warranty period, and it will be paid after that.
