What to do if the touchpad does not work

Although modern mobile and stationary computer models in terms of the components used are very similar, there are a number of features that allow even a simple description to accurately indicate what exactly is being talked about. For example, a component such as a touchpad is inherent only in portable solutions, while in a stationary one a mouse is used.

Physically, the touchpad is a small touchpad built into the notebook's case in front of the alphanumeric keypad. In order to make the cursor move in the programs, it is enough to hold a finger along it. Accordingly, a simple point touch is treated by the system in the same way as a mouse click. Quite a convenient solution, since there is no need to carry a mouse to control the graphic interfaces. However, sometimes notebook owners are puzzled why the touchpad does not work. It's hard to believe, but even this seemingly reliable device can not function properly. So why does not the touchpad work?

Adjust settings

Since there are a number of possible reasons why the touchpad does not work, it is necessary to perform a simple diagnosis yourself to determine it. First of all, it is necessary to decide how the fault is manifested: the sensor does not react to touching the finger, or the cursor moves unstably, as if it "sticks".

As in the first, and in the second case, first of all, it is necessary to install the appropriate driver in the system. This control program can be found on the disk that comes with the laptop, or download from the manufacturer's website. The type of the touchpad is specified in the specification to the computer. So, if the touchpad does not work on Asus laptop , you should find on the company's website in the "Support" section a description of the model you need, where the type of touch panel is specified exactly. After that (if the cursor moves unsteadily), go to the "Mouse" item in the control panel and change the sensitivity of the slider.

Disabling by regular means

However, much more often users are faced with the fact that the touchpad does not work completely, but completely. Surprisingly, the main reason for this lies in the actions of the person himself, and not in the damage to the components. The fact that laptop manufacturers provide for the possibility of disabling the touchpad by pressing a certain combination of buttons. The peculiarity is that in this way the disabled panel can not be activated by simple reinstallation of the operating system. The computer simply "remembers" the state, and to restore functionality, you must press the corresponding combination of buttons again. That is, if the touchpad does not work, you need to press Fn and one of the system F (1-12). Usually, the image of the touch panel is applied to the desired one. Note that there are models of portable computers that automatically block the work of the sensor when a USB mouse is connected.

System BIOS

Testing and configuration of any computer allows you to make adjustments to the work of many components. Therefore, if the touchpad does not work, then you need to make sure that its work is not prohibited in the BIOS. To do this, immediately after turning on the laptop, you need to press F2 (depending on the manufacturer), select the Advanced section and set the status of Enabled to the Internal Pointing Device line.

Hardware Problems

Since the touchpad is connected to the motherboard via a loop, sometimes the latter is removed from the connector, causing malfunctions. It is necessary to disassemble the laptop and check the condition of the loop. Also, due to high internal temperatures, there may be a situation where the controller of the touchpad itself is damaged. In this case, please contact the service center.
