I have a Lenovo G570. I switched from windows 7 Home Premium to Windows 7 Ultimate (64-bit both of them) and I removed all the partitions. When I try to use the volume or brighness feature by pressing down the Fn key and the volume-up/down or the brightness, it wont work. I might have erased something I shouldn't have. How do I get my "Fn" key to work ?
To fix the issue, please install the following drivers:
1. The display driver available on lenovo consumer website.
If you have Intel display card then the version for the driver should be 184.108.40.2062
