Volume +/-, and screen brightness work but there is no ondisplay icon shown, so, therefore, the actual Windows 7 software isn't toggling these. The HotKey Patch and HotKey Integration were both successfully installed. I did all the Windows Updates, and then proceeded with installing the Leonvo Drivers, which I've saved a copy from last time doing a fresh install which was in Dec 2011. I just did a new install of Windows 7 onto a new SSD on my X61.
