Dear John,Although you did not mention your laptop model, Medion laptops use a combination of the 'Fn' key with one of the function keys on the top part of your keyboard to enable/disable the touchpad, that can be F3 or F6 or F8. So, try pressing the 'Fn' key and, while keeping it pressed, press also the F3 key and release them. Check if the touchpad now works. If it does not, try the same operation with 'Fn' plus the F6 keys or 'Fn with the F8 keys.If none of these combinations works for you, maybe you will need to download and re-install the driver for your touchpad, from the Medion web site. go to
www.medion.com site, select your country or region and then look for the drivers page for your laptop model. Select the driver for the touchpad offered there, download and install it in your machine.Hope this helps! Regards,Miguel L. Martins
