Why is the computer touchpad suddenly unusable

Touchpad hardware problems: At this time, it is best to contact after-sales service to solve the problem, the general notebook touchpad does not respond, and most of them appear in laptops that have been used for a long time.

If it is in use, it will fail and not respond. This may be due to accidentally turning off the touch screen, generally press fn (function key) + f6 (different keys for different notebooks, there is an image of the touchpad on the buttons) to unlock it. Some computers also have buttons that open and close the touchpad directly.

Then install it to see if your driver is corrupted, and what brand of notebook you are, some notebooks have a shortcut to turn off the touchpad.

The reasons may be:, possibly a touchpad driver.

It is damaged or accidentally uninstalled by the user.

The laptop touchpad is turned off. Some notebooks can turn off the touchpad through settings, so if you accidentally turn off the touchpad, it will naturally cause the touchpad to malfunction.

Caused by a virus in your computer.

The laptop's touchpad is faulty (e.g., water ingress, foreign objects inside, etc.).

Focus on the following aspects:First, check if the touchpad function of the notebook is locked and turned off.

If you accidentally operate the computer and mistakenly press the button to turn off the touchpad, you may turn off the touchpad of the notebook, so when the touchpad is not available, you can try to press the FN+F6 combination to turn on the touchpad (Note: Some notebooks may use FN+F6 to turn on or off, but some brand notebooks are different, you can check the instruction manual of the corresponding brand and model notebook, or search for the following information).

Detect if the touchpad driver is normal.

Detect whether there is a problem with the lower driver, and if there is a problem, fix it.

1.What to do if the laptop mouse touchpad does not move.

The analysis is as follows: 1. Check whether the touchpad is turned on, and press the shortcut key combination "FN+F9" (this is taking ASUS notebook as an example). Other notebooks are also this icon.

2. If the touchpad is open, it may be that the touchpad program has been damaged or the user has accidentally uninstalled it. Just reinstall it. Use the software "Driver Wizard" to detect it, and you can install it.

3. If there is a virus in the computer, scan it with anti-virus software and remove the virus.

4. If none of the above methods can solve the problem, open the "Control Panel" and select "Hardware and Sound".

5. Select the blue font "Mouse" under "Devices and Printers" to enter.

6. In the mouse properties, click "Hardware" in the upper taskbar to check whether the device is running normally.

Extended information: 1. Touchpad (touchpad or trackpad) is an input device widely used in laptops. It senses the movement of the user's finger to control the movement of the pointer.

2. The touchpad can be seen as a substitute for a mouse. Touchpads can also be found on some other portable devices, such as personal digital assistants and some portable AV devices. Due to design limitations, touchpads are usually no larger than 20 square centimeters.

3. Among them, Apple's MacBook Pro is equipped with the most excellent multi-touch trackpad, which can be used for gestures such as zooming in and out of the display, as well as handwriting input. It makes use of Apple's multi-touch technology. The technology was first developed and patented by Fingerworks (a small San Francisco company that was later acquired by Apple) and was first used on the iPhone.

4. The touch board is made into an array of rows and columns with a printed circuit board; The printed plate and the surface plastic laminate are bonded on both sides with strong double-sidedness, and the principle of inductive detection is capacitive sensing. A special integrated circuit board underneath the surface of the touchpad continuously measures and reports this trajectory to detect the movement and position of the fingers.

5. The touchpad is an input device that can move the cursor on a smooth touchpad by sliding the finger. It is easy for beginners to use. Because the thickness of the touchpad is very thin.

Therefore, it can be designed in ultra-thin laptops or keyboards. And it's not a mechanical design. It is very easy to maintain.

6. Its working principle is that when the user's finger approaches the touchpad, the capacitance will change, and the touchpad's own control IC will detect the capacitance change and convert it into coordinates. The touchpad uses capacitive sensing to know the movement of the finger and is not sensitive to the heat of the finger. When a finger touches the board, the electrostatic field on the board changes.

A touchpad sensor is just a finger trace conduction line printed on the surface of the board.

<>1. The switch is not turned on

Almost more than 90% of laptop touchpads come with independent switches, if users find that the laptop's touchpad is not working properly, be sure to check the switch first, taking ASUS series laptops as an example, you must press the "FN+F10" key combination on the keyboard at the same time to be able to turn it on.

2. The settings are incorrect

In addition to the fact that the user does not turn on the touchpad switch, there is another special case, and that is the user setting error.

3. Drive error

If you try the first and second methods, and find that the touchpad still can't be used normally, then you need to consider that it is caused by a driver error, and there are many reasons for the driver error, often because the system or driver is damaged by a virus or Trojan horse, and it is impossible to solve this kind of problem in most cases.

There are two workarounds for encountering this situation:

One is to call the official after-sales service**, and ask the other party to send the driver to their mailbox (you need to know the specific model of the computer, but most users can't remember the model), and then install it yourself.

The second is to go directly to the computer after-sales inspection and maintenance, free of charge during the warranty period, and the maintenance cost outside the warranty period is not high (there is a high probability of reinstalling the system or replacing the touchpad, and it is not recommended to repair or replace it by yourself).

Fourth, the touchpad is damaged

If the touchpad fails before the user pours water, drinks and other conductive liquids on the touchpad, most likely the computer is caused by water burning the touchpad. Maybe many friends will say,After entering the water, I shut down the phone to clean up the water stains,Then you can turn on the machine normally,It's just that the touch pad is not good,It's too troublesome to go to the after-sales service,If you think so, it's wrong,As long as there is no disassembly and cleaning,Those water stains will stick to the internal components of the computer,Although it seems that just the touch pad is not easy to use,But with the accumulation of use time,Motherboard、Memory、Hard disk and other components also have the possibility of damage,And the probability is particularly high。

The sudden failure of the computer touchpad may be due to the following reasons:

1. The touchpad switch is not turned on: Some computer touchpads have switches, if the switch is not turned on, then the touchpad cannot be used. You can check your computer's manual or look for the touchpad switch on your computer to make sure it's turned on.

2. Touchpad driver problem: If there is a problem with the computer touchpad driver, then the touchpad cannot be used. You can check the status of the touchpad in Device Manager, and if it shows an exclamation point or question mark, you will need to reinstall the driver.

3. Touchpad hardware failure: If the touchpad hardware fails, then the touchpad needs to be replaced or the computer needs to be repaired. Try testing the same touchpad on a different computer, and if it still doesn't work, you'll need to replace it.

4. Touchpad setting problem: If there is a problem with the computer touchpad setting, then you need to reset the touchpad. You can find the touchpad settings in your computer's settings to check if they're set up correctly.

It should be noted that the sudden failure of the computer touchpad may be caused by a variety of reasons, and the specific reasons need to be judged according to the actual situation. If you are not sure how to solve the problem, it is recommended that you contact the computer manufacturer or a professional computer repairer for help.

The computer touchpad suddenly can't be used, and the solution is as follows

If your touchpad isn't working, it's possible that the driver is missing or outdated...In"Get started"on, search"Device Manager"and select it from the list of resultsIn"Mice and other pointing devices"Next, select the touchpad, turn it on, and select"Drivers"tab, and then Source Dust Selection"Update the drivers"。.

If Windows can't find a new driver, look for one on the device manufacturer** and follow its instructionsIf these steps don't work, try uninstalling the touchpad driver: Open Device Manager, right-click (or long-press) the touchpad driver, and select"Uninstall"。

Lu cracked and stuffy. Restart the device and Windows will attempt to reinstall the driver. That's it.
