Your laptop's touchpad can be used to replace most of the functionality of a mouse. Its buttons provide the same click functions as a mouse and, while it doesn't have a mouse wheel, it can scroll through browsers and documents just as a wheel does. Unlike many mouse wheels, the touchpad can scroll both horizontally and vertically. Run your finger up the pad's right edge to scroll vertically and along the bottom edge to scroll from side to side. Enable this feature though the Windows mouse settings dialogue box.
Click the "Start" button in the screen's lower-left corner. This opens the Start menu.
Type "mouse" into the menu's search bar. Click "Mouse" from the search results, under the heading "Control Panel." This opens the "Mouse Properties" window.
Click on the "Device Settings" tab. The "Devices" box will list your touchpad, and it will automatically appear highlighted.
Click the "Settings" button. This launches your device driver's settings dialogue box.
Click on the entry for "Scrolling." If the subheading "One-finger scrolling" appears, click on that next.
Check the boxes for "Enable vertical scrolling" and "Enable horizontal scrolling."
Click "OK" to close this and the main "Mouse Settings" window.
Restart your computer.
If you find buttons missing or disabled in steps 3 or 4, reinstall your device driver from the installation disc that came with your computer. If you no longer have the disc, download the driver from your manufacturer's website.
