Dell Latitude E5550 - On Screen Volume and Screen Brightness Indicator

[ironinhead]

Hello,

My laptop: Dell Latitude E5550 - 15.6" FHD - Core i5 5300U - Intel HD Graphics 5500 - Windows 7 Pro 64-bit - 8 GB RAM - 500 GB HDD.

Does anybody know what drivers/software is responsible for displaying On Screen Volume and Screen Brightness Indicator (while pressing Fn+F2,F3,...) ?

What I've found so far that the Dell QuickSet may do the work (link to this solution: http://www.sevenforums.com/sound-au...hen-using-keyboard-audio-volume-controls.html), but I couldn't find a compatible version of this soft with Dell Latitude E5550.

I don't know if this will help but here is the link to the Dell Keyboard Unifying Application.
Give it a show.

If that doesn't help, there is a Dell users forum with users that are knowledgeable about Dell's and they should be able to help.
