How to Enable a Thinkpad & a Touchpad
Laptops are all-in-one PCs, with all of the essential peripherals built into the frame. Lenovo's ThinkPad laptops use a touchpad, which is a compact pointing device used in place of a bulky and constrictive mouse. Sometimes called desktop replacements, casual power users and professionals might prefer to connect a USB mouse to the laptop because it is easier to control vs. a touchpad. To prevent further erroneous touchpad movements, users can disable the touchpad. If you are unsure how to enable the touchpad, you can use a utility in the operating system to access those functions quickly.
Click "Start." Type "Mouse" in the search box at the bottom of the "Start" menu. Press "Enter."
Click the "UltraNav" tab at the front of the dialog box.
Place a check mark in the box next to "Enable TouchPad."
Click "Apply" and "OK" to enable the touchpad on the ThinkPad.
