The Acer Aspire line was first introduced in 1999 as a series of desktop computers; over time, a range of notebook and netbook computers was added to the line-up. As with most laptop PCs, the touchpad in an Acer Aspire laptop is manufactured by Synaptics Incorporated, which also provides software drivers for the device. If you are working in an area with high humidity, experience accidental activation of the touchpad during normal operation or if you have difficulty controlling the pointer, you may benefit from adjusting the touchpad's sensitivity settings via the "Mouse" control panel.
Turn on the computer and log into Windows as normal. Open the "Start" menu and click on the option labelled "Control Panel."
Double-click on the icon labelled "Mouse.". The "Mouse Properties" window will open. Navigate to the tab labelled "Device Settings." Click on the button labelled "Settings." A window labelled "Properties" will appear.
Examine the left panel of the "Properties" window and expand the option labelled "Sensitivity." Click on the option labelled "Touch Sensitivity."
Reduce the touch sensitivity setting by moving the slider to the right, towards the "Heavy Touch" label. Experiment with different levels of sensitivity until you find one suited to your needs.
Click on the button labelled "OK" to close the "Properties" window; repeat with the "Mouse" control panel. Your new touchpad sensitivity settings are now saved.
- If you wish to restore your touchpad settings to their original values, click on the "Defaults" button in the lower-left corner of the "Properties" window.
- You can disable the touchpad entirely by pressing the "Fn" and"F7" keys simultaneously; repeat the key combination to re-enable the device.
- Confirm that your Acer Aspire has the latest version of the touchpad driver installed; go to Acer's "Driver Download" page (see Resources below), select your device model from the list of available options and look for a "Touchpad" entry under the "Category" header.
- The "Properties" window also contains an option labelled "Palm Check," a feature designed to prevent unintended pointer movement as the result of accidental contact with the touchpad; you may wish to experiment with this feature's settings instead of (or in addition to) those for managing touchpad sensitivity.
- You can temporarily slow down the pointer's movements by selecting "Slow Motion" from the "Properties" window and choosing a hotkey; press and hold down the hotkey to enable slow motion, then release when you are finished.
