The Acer Aspire is a laptop model that has a built-in "mouse pad," also called a "touchpad." The user runs his or her finger across the mouse panel to move the cursor. If your mouse pad no longer responds to your touch, it may be due to a build-up of dirt and grease. Another common problem is having an outdated or damaged mouse pad driver. These problems can be quickly resolved without having to take apart the laptop.
Hold down the "Fn" key, which is found at the bottom left corner of the keyboard.
Press the "F7" key once while holding the "Fn" key.
Look for a message that says "touchpad enabled."
Go to "Start" > "Control Panel" > "System and Maintenance" > "Device Manager."
Double-click on "Mice and other pointing devices" to expand the options.
Right-click "Synaptics Touchpad" and then click "Search automatically for updated driver software." Wait for the computer to scan and install new drivers.
Restart your laptop.
Clean the touchpad with rubbing alcohol if it appears greasy or dirty.
