Dell laptop brightness control not working?! [SOLVED]

Description of the brightness control problem

If you have a recent Dell laptop and are doing a clean install of Windows 8.1 (and possibly Windows 10), you may encounter an issue where the brightness controls (F11/F12 down/up) do not function properly. Specifically, the buttons pull up the Windows 8 brightness control slider BUT the changes do not take effect 🙁

Solution

Thankfully, the fix was simple. Install the latest Intel HD video drivers! As soon as I installed the latest drivers, the buttons immediately started working (I didn’t even have to reboot).

Download the latest drivers here:

use dl link then narrow by OS and your GPU/CPU version.

Applies to: Dell Inspiron 11, 3000 series, 2-in-1 (and others)

PS on older laptops, simply installing Dell Quickset was sometimes enough to enable brightness control… with Windows 8 it appears that the latest video card drivers are definitely a necessity as well.
