Change your touchpad settings through the pad's driver, which manages interaction with the operating system. The driver is in the Hardware and Sound section of the Control Panel.
The touchpad is a fixed part of the laptop. However, the computer treats it partly as an external device. Touchpad settings include sensitivity, speed and functionality of the buttons. To change these settings, click on the Start button, then select Control Panel.
Click on Hardware and Sound to open a list of hardware configuration tools. If you do not see Hardware and Sound in the Control Panel window, check the upper left of the Control Panel and click on View By. Select Category from the drop-down menu.
Select the Device and Printers section to open the Mouse Properties dialog box. You must install and ensure proper functioning of the touchpad's drivers to access the Mouse Properties settings.
Click on Device Settings, then select Settings to open the Settings dialog box. Modify your touchpad by clicking on the plus sign in front of the setting you want to change. These settings vary depending on the manufacturer and model of laptop. To save the changes, click on Apply. Click OK to close the dialog box.
