I have a g550 Lenovo and after installing Win Vista Home Premium SP2 , i do not have the on screen display or we call it hotkey. The FN function does not work at all.
Different drivers have been installed such as Onekey recovery and video driver, but do not work.
Where is the hotkey driver?
The hotkey driver can be found when you are installing Lenovo Energy Management software.
There is a driver called "Utility" during the installation process. Installing this will enable the FN to work.
how can we improve it?
