The touchpad on a laptop is a convenient and efficient feature, but if it is not set to your liking it can be frustrating. In some Acer laptops there are issues with touchpads that are too sensitive. You have choices in your touchpad settings that range from adjusting its speed to disabling it altogether. In the system tray in the bottom right corner, there should be a touchpad icon that you can use to adjust your touchpad. If not, there are other ways to change your touchpad settings.
Click on the "Start" button and select "Control Panel."
If you do not see all the "Control Panel" icons in the pane to the right, look at the top of the left-side pane for "Switch to Classic View" in Windows XP or "Classic View" in Vista or Windows 7.
Double-click on "Mouse" to open it and select "Mouse Properties."
Select "Device Settings."
Select "Tappings" and remove the check from the box for "Enable Tapping."
Choose "File" then "Exit" twice to close the Mouse and Control Panel boxes.
An alternative is to turn off the touchpad entirely by holding down the "Fn" key and pressing the "F7" key. To turn the touchpad back on, repeat this procedure.
