Touchpad in Toshiba® Satellite U500
The touchpad in laptops is analogous to the mouse in desktops. It is the most commonly used pointing device in laptops and netbooks. Touchpad is an advanced, touch-sensitive interface solution that senses the position users touch on its surface to provide screen navigation, cursor movement, application control, and a platform for interactive input. A touchpad has many advantages; it is configurable, that is, it can be modified to reflect the users’ needs, and it is reliable, accurate and easy to use. Touchpad includes patented features such as Hand Check, Virtual Scrolling, Tap Zones, and Edge Motion etc. A touchpad operates in different ways and similar to different hardware devices, it is also prone to errors.
- Firmware issues
- Virus attack issues
- Driver related issues
Like every other hardware input device, the touchpad also has firmware. This firmware decides the behavior of the track pad like zooming in and zooming out on moving your fingers in different ways. Any change to the firmware will render the track pad useless as the behavior of the device will change. If the firmware is modified then the device will perform in unexpected ways and the only way to correct this would be to install good firmware.
Virus attack issues
Another possible reason for software issues in track pad is attack by viruses. Some viruses attack by affecting the input devices of the computer so that they input incorrect characters. The track pad is no exception; it is also affected by certain viruses. Installing a good antivirus program is one way to keep away malicious programs. Antivirus software detects and deletes malicious software and intrusions. Installing a good firewall is also a good idea to make sure that the unwanted codes are kept out.
Another possible reason for software related problem is missing drivers or installation of incorrect drivers. Sometimes the drivers for the track pad might be installed, but it might not work properly. This is usually due to incorrect drivers installed for the device or no drivers being installed. To correct this you can install the correct driver for the device provided to you by the manufacturers or you can download and install it from the Internet.
