External cleaning touchpad

First you need to make sure that the touchpad panel is clean, because it is likely that due to dirty particles, the device simply does not respond to the touch of your fingers. Wipe the touchpad with a soaped swab first, then walk on it with a damp cloth and let it dry.

Do not worry about the fact that the tampon or cloth will be wet. The touchpad does not respond to moisture, because of what you do not damage it that way.

Check for connection using keys

It is likely that the touchpad was simply disabled. All laptops have “quick keys” with which you can adjust some elements of the laptop.

So, simultaneously pressing the key combination Fn  and the necessary button in the top row on the keyboard, you can enable and disable the touchpad.

It is important to remember that on different laptops such combinations may be different. Just look for the touchpad-like icon in the top row.

Check for device conflict

Perhaps the connected mouse and touchpad on the laptop are in conflict with each other. If you checked the first two options and their solution did not help, then try to disconnect the mouse from the laptop and then turn on the touchpad, as described above.

Utility use

Another way to solve this problem may be the presence of an icon on the panel near the clock (see the screenshot below). If you have such an icon, the touchpad can be activated using it.

Test for connecting the loop

To check this option, you will need to get to motherboard  laptop. To do this, open the back panel (on some models top panel), unscrewing the bolts on it.

Note: different models laptops open in different ways, so you cannot give specific advice on how to open a laptop.
  When you see the “motherboard”, see if the cable has disconnected from it.

Driver installation

Do not forget that the work of most laptop components requires the presence of drivers.

Driver is softwarethat interacts with a particular part with the laptop's operating system. So, for the mouse, a connected keyboard or the same touchpad, these drivers are required.

It is important to remember that each component has its own drivers. One universal driver for all occasions does not exist.

Not at all the fact that the above methods will help you. If none of the above has worked, then we recommend that you simply take the laptop to a service center, where you can be helped to solve the existing problem.

One of the featureswork on a laptop is that it does not necessarily use a mouse, it replaces the touchpad. Question why the touchpad does not work on a laptop, many users care because  in the event of a breakdown, there is a lot of inconvenience, especially if you do not have a mouse at your disposal.The touchpad is a touchpad that reacts to touch and finger movement, which moves the cursor along a predetermined path. The problems that arise are often not his correct setting.

Step-by-step instructions for restoring the touchpad

1. No matter how funny it sounds, but first make sure that it is clean. This panel is cleaned using a soapy swab. Next, wipe with a damp cloth and let dry. About 5% of calls to our service center is solved in this way. It is very important to remember that the touch panel does not respond to wet and greasy hands!

2. Make sure that the correct sensitivity parameters are set in the settings and that the touch panel device touchpad  "works fine". In this case, this device is asus touchpad  ps / 2.

3. Check for the presence of all necessary drivers for the touchpad. It is very important that the driver window contains entries from the manufacturer with a version higher than 1.0. Often standard windows drivers  (especially often found in systems 7 and 8.1) do not function correctly.

4. When the touchpad does not work as a whole, then to eliminate the cause, you need to exclude simple options malfunction. First make sure the panel is connected. In order to connect the panel, you can use several methods:

Fn key combination with one of the keys F1-F12;

Press the on / off button on the touchpad (it is not available on all laptop models);

Enable with a utility that is displayed next to the clock;

Disable the mouse, which automatically turns on the panel (device conflict).

Other possible problems and their solution

This all refers to software issues, and if after the options provided, the sensor still does not work, then the cause goes into the category of hardware.

First, make sure to connect the cable to the motherboard. There are cases when during transportation the cable falls out of the connector. You can fix this problem yourself, but in case of doubt it is better to contact the service center.

Secondly, the sensor may stop working as a result of mechanical damage. In this case, it must be completely replaced. Exceptions are cases of weak mechanical damage that can be corrected.

If the touchpad does not work in conjunction with other devices (USB ports, keyboard, etc.), then the fault lies in the motherboard, the intervention in which is carried out exclusively in the service center. As a result, if you find problems with the touch panel, before going to the service center, conduct an independent inspection possible reasons  breakdowns that help save your time and money.

If only scrolling or finger gestures does not work

Often the problem lies not so much in the complete loss of functionality, as in the device’s partially working capacity, and if scrolling on the touchpad (the so-called scrolling) or special gestures for fingers does not work for you, the whole problem lies in the curvature installed drivers. If their reinstallation did not help, then you will have to contact the service center, as it is impossible to exclude a physical failure of the panel (for example, after filling it with liquid with a dry matter content). Another thing is if scrolling on the touchpad stopped working for no apparent reason. In this case, these are 99% curved drivers - most often similar problems with scrolling are found on devices Acer, ASUS and Hewlett-Packard (HP).

By the way, a lot of useful information can be found in the article "What to do if the laptop is flooded."
