The only other thing I've changed since then is upgrade my BIOS to Middleton's version (to enable SATA 2 speeds). Hi friends, in this tutotial i will show you, how to solved 'fix screen brightness Not Working in Windows 7, 8, 8.1 and 10 and laptop or computer pc screen b.

This worked before on my prior Windows 7 HDD install. I've done a Lenovo System Update 4, and it didn't find any pertinent update for the HotKeys. I did a full uninstall of it, reboot, and install of it again. As a result, things like the Fn F5 don't work, and I'm not able to toggle my Bluetooth on because of this.Īny idea? I checked the Lenovo site, and I tried downloading the latest version of the installer, which happens to be the same version as I already have. 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.
