Causes of computer touchpad failure:

1. The switch is not turned on

Almost 90% of laptop touchpads have independent switches. If Users who find that the touchpad of their laptop cannot be used normally must first check the switch. Taking ASUS series laptops as an example, they must press the "Fn F10" key combination on the keyboard at the same time to turn it on. As shown below:

When you press this key combination, a prompt to turn on or off the touchpad will appear on the computer screen. As shown below:

After "Touchpad is on" is displayed, it can be used normally.

2. Setting error

In addition to the situation where the user does not turn on the touchpad switch, there is another special situation, that is, the user settings error. First open the "Start Menu" and click " Gear" icon and enter "Settings". As shown below:

After entering "Settings", find "Device" in the pop-up interface. As shown below:

Click to enter the "Settings" option, find "Touchpad" in the pop-up interface, then click this option, the interface on the right will switch, and then find "Keep the touchpad on when connecting the mouse" Status", check this option.

When the user does not check this option and inserts an additional independent mouse for use, the touchpad will fail. Only when this option is checked, the touchpad can be used together with the mouse.

3. Driver error

If you find that the touchpad still cannot be used normally after trying the first and second methods, then you need to consider that it is caused by a driver error, which leads to a driver error. There are many reasons, often caused by the system or driver being damaged by viruses or Trojans. Although you can download the driver from the official website and reinstall it, in most cases this type of problem cannot be solved. There are two solutions to this situation. : First, call the official after-sales phone number and ask the other party to send the driver to your mailbox (you need to know the specific model of the computer, but most users cannot remember the model), and then install it by yourself; second, go directly to the computer after-sales inspection and repair. It is free during the warranty period, and the maintenance cost outside the warranty period is not high (it is highly likely that the system will need to be reinstalled or the touch panel will be replaced, and it is not recommended for individuals to repair or replace it by themselves).

4. Damage to the touchpad

If the user poured drinking water on the touchpad before the touchpad failed, it is probably caused by water entering the computer and burning the touchpad. If you encounter In this case, the simplest way is to shut down the phone first, and then take it to the after-sales service department for disassembly and inspection. Many friends may say that after the water got in, I shut down the phone and cleaned up the water stains, and then it could be turned on normally, but the touchpad didn't work. It was too troublesome to go to after-sales service. If you think so, you are wrong, as long as you don't disassemble the phone and clean it. , those water stains will stick to the internal components of the computer. Although it seems that the touchpad is not easy to use, with the accumulation of use time, the motherboard, memory, hard disk and other components are also likely to be damaged, and the probability is particularly high.

5. Other faults

In addition, there are also some abnormal faults that cause the touchpad to not work, such as lack of system functions, loss of driver files in the computer, driver conflicts, etc. , may cause the touch panel to malfunction, but this type of failure cannot be determined directly. You need to see the actual laptop and then conduct testing to determine the cause of the failure.
