We have a  G570 with Windows 7 64bit,  


I have updated the BIOS but the Fn+F5 touchpad combination doesn't work at all. Then I uninstalled Lenovo Energy software and installed the latest version  . The situation is the same. Only this function doesn't work, everything else ok.



If The Fn+F5 Button does not work please follow the instructions below.


  • Uninstall the Energy Management and download and install the latest version and also try to update the touchpad drivers  G570 Drivers & Software
