I just inherited an AOD255E from a former employee and was unable to adjust the screen brightness. On power or battery the screen seemed to be at full bright.
The Acer launcher software is installed and working, I can use the function keys do control the volume, mute, etc.
When I go to the display properties in Windows, the brigtness indicator moves back and forth when I use the function keys but the screen brightness does not change.
For safety and other issues I did perform a full factory reset using the acer utility and the behavior is the same.
I tried making changes in the Intel Graphics Display software with no luck.
Any tips, suggestions or points to posts I may have missed on the topic would be greatly appreciated.
Thanks in advance.
