Touchpad or touchpad on the laptop is a built-in mouse, which is designed to make the use of a portable computer more convenient. This device was invented back in 1988, and popularity to the touch panel came only after 6 years, when it was installed on Apple's PowerBook notebooks.
And although many users still prefer to use a separate mouse , disconnecting the touchpad, we all have at least sometimes, but there are situations where there is no mouse at hand and you need to use the built-in mouse. What to do if the touchpad on the laptop has stopped working - we'll find out about it below.
Why does not the touchpad on the laptop work?
There can be several reasons. Let's start in order with the most simple. In 90% of cases, everything is solved by simply turning on the touchpad on the keyboard. For this purpose special combinations are intended, when one key is the Fn function button, and the second one is one of the 12 F at the top of the keyboard.
Here are the combinations for different laptop models:
- Acer - Fn + F7;
- Asus - Fn + F9;
- Dell - Fn + F5;
- Fujitsu - Fn + F4;
- Gigabyte - Fn + F1;
- Lenovo - Fn + F6.
But not all manufacturers are so simple. For example, when the touch panel does not work on the Asus laptop, you need to press the corresponding key combination, but if the touch panel on the HP laptop does not work, everything is different.
This and some other companies are moving away from the usual layout of the keyboard, taking out the button to turn the touchpad on the panel itself, placing it in the upper left corner. It has a light indication for easy recognition of the on / off state of the touchpad. You just need to double-click on the indicator, which is a touch button.
Another reason why the touch panel on the laptop does not work is trivial contamination of the panel and touching it with wet fingers. You just need to wipe the touchpad with a damp cloth and then wipe the surface dry. Well, or wipe your hands.
Software inclusion of the touchpad
After reinstalling the OS, there are sometimes problems with the correct operation of the touch panel. This is due to the device driver. You just need to install the necessary driver from the disk that comes with your laptop or download it from the manufacturer's website.
Less common, but still taking place is the disabling of the touchpad in the laptop's BIOS. And to fix the problem, you have to go into this very BIOS. You can do this at the time the computer is booted by pressing a certain button. Depending on the brand of laptop, it can be Del, Esc, F1, F2, F10 and others.
To determine the moment for clicking, you need to monitor the inscriptions - the name of the key should appear to go to the BIOS. After logging on, you need to find a menu item that is responsible for managing the embedded devices and viewing its status.
The activation / deactivation of the touchpad is determined by the words Enabled and Disabled, respectively. After selecting the desired state, you need to save the changes.
Hardware failure of the laptop touchpad
When none of these methods has had the desired effect, creeps in doubt about the hardware, that is, the physical breakdown of the touchpad. This may be a poor connection to the motherboard or mechanical damage to the panel. In the first case, simply fix the connector.
To struggle for an independent elimination of such causes is necessary only in the case when you are completely confident in your knowledge and skills in analyzing and collecting a laptop. Otherwise - we recommend that you seek professional help from a specialist.
