Recently I upgraded three different Dell laptops to Windows 10. The first was a Dell Inspiron 11 2-in-1, the 2nd was a Dell Latitude E5450, and the 3rd was a Dell XPS 13 (2015 Infinity Display). While I love Windows 10 so far, there is one major annoyance: brightness adjustment no longer works! i.e. when you press Function Key + Brightness Up/Down, the onscreen brightness meter pops up but the actual brightness adjustment does not work 🙁
Thankfully, after some experimentation I finally resolved the issue 🙂 Here is how to fix the brightness adjustment on Dell laptop’s running Windows 10:
#1 Go to Device Mananger
#2 Open Display Adapters
#3 Right click on each Display adapter and choose “Update Driver”
Let windows do it’s thing (which may take a while since the driver will need to be downloaded).
After that, voila you should have your brightness adjustment back! 🙂
