The brightness and volume touch buttons on the front of this all in one machine will not work. The buttons light up but do not actually do anything when in windows.
If you boot to the BIOS the brightness buttons work but not in Windows.
I have looked at the drivers for this model and there is not one listed for these touch buttons
I am using Windows 7 Enterprise SP1
Model: HP Eliteone 800 G1 AIO NT 23
