Touchpad not Working - How to Reset to Default

Try the following - connect a usb Mouse where required.

• Hold down the Windows key and press R
• Into the Run window, type devmgmt.msc and hit enter.
• In the Device Manager window, expand Mice and other pointing devices.
• Right click the Synaptics device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
• When complete, shutdown the notebook.
• Disconnect any peripheral, including any usb Mouse.
• Tap away at the esc key as you start the notebook to launch the Start-up Menu and then select f10 to enter the bios menu. Press f9 to load the defaults ( this is sometimes f5, but the menu at the bottom will show the correct key ), use the arrow keys to select 'Yes' and hit enter. Press f10 to save the setting and again use the arrow keys to select 'Yes' and hit enter.

Let windows fully load for a few minutes before checking the touchpad function.
