How to Raise Your Touchpad Sensitivityby Aaron Parson
You can adjust the sensitivity of your touchpad in two ways. Using Windows Control Panel, you can make the cursor move further with the same amount of motion on the pad, but this can also make it more difficult to aim the pointer accurately. If you have a Synaptics touchpad -- the most common brand -- you can also adjust the touchpad's pressure sensitivity, changing how hard you need to touch the pad before it picks up movement.
Cursor Movement Speed
Open the Mouse control panel in Windows by searching for "Mouse" on the Start screen. If you don't have the Windows 8.1 update, you'll need to click "Settings" on the search bar to see the Control Panel. Open the "Pointer Options" tab in the Control Panel and drag the "Select a pointer speed" bar to the right to raise sensitivity. This setting will also affect any USB mice you connect.
Synaptics Pressure Sensitivity
If you have a Synaptics touchpad, you will see an additional tab in the Mouse control panel labelled "Device Settings." Open this tab and click "Settings." Click the triangle next to Pointing to expand the menu. Select "Sensitivity" and then click the gear icon. Drag the slider to the left to raise sensitivity, making your touchpad work with a lighter touch.
