How do I change touchpad sensitivity on my laptop?
Click on the "Start" icon and select "Control Panel."
Next select "Mouse" under "Hardware and Sound."
You can also left-click the touchpad while the cursor is anywhere on the desktop.
From that screen, choose "Mouse Pointers." Select the "Buttons" tab at the top of the dialog box that opens. This shows the type of touchpad device installed on your laptop. Set the touchpad for right or left-handed use from this dialog box. You can adjust the double click speed of your computer as well. When you finish making any changes, click "Apply." Pick the "Device Settings" tab from the dialog box now. You can see the touchpad for your Vista machine highlighted on this screen. Select "Settings." Read the information provided in the next dialog box. It gives you options for tapping your touchpad, using the buttons, scrolling, pointer motion and sensitivity. Make any changes you want from the various topics. When you make a change, click "Apply." Click "OK" when you finish making all your changes. Do some work on your computer and if the touchpad is still too sensitive, return to the "Mouse" menu and continue to adjust the settings until you get them just the way you want them.
