The brightness in Windows Mobility Center does not correspond with the on screen display

The brightness level as reported in the Windows Mobility Center in Windows 7 may not correspond to the brightness on the Dell Quickset On Screen Display (OSD), which will show the brightness at the maximum level. Adjusting the brightness level using the <Fn> + <Down> or <Up> key combinations has no effect on the reported level with the Quickset OSD. Additionally, after a few moments of adjusting the brightness using the keyboard combinations, the Windows Mobility Center will revert to the maximum brightness setting (Figure 1).

Currently, updating the system BIOS and installing a new version of Quickset are the only two possible solutions, but may not resolve the compatibility issue. Old versions of Quickset are incompatible with Windows 7.
