I installed Windows 7 Pro 64 bit on my Lenovo G500s. After the installation I managed to install most of the drivers, however, when I looked through the device manager I saw three unknown devices and all of them with root/LenovoVhid.


Is there a driver I have missed or anything I can do to rectify this?


There is a possibility that that you might have missed installing the Lenovo Energy Management Software or the Lenovo Energy Management might have not installed properly.


If you have installed it, try reinstalling it and download the Lenovo Energy Management from the link below.
