Problem on screen brightness adjustment(Windows 7 Ultimate 64bit)

#1
Hi, I observed a problem on my new pc with windows 7.

When I try to adjust the screen brightness, the adjustment slider is always in minimum in Control panel>Hardware and Sound>Power Option, as shown in this picture


but once I go to the "Edit Plan Settings", the slider is in maximum position, as shown in this picture


I can adjust the brightness under the "Edit Plan Settings" but not in the "Power option". Something must be wrong here, does anyone know how to fix this? Many thanks!

If this is not already overtaken by events, what is your goal--are you trying to adjust the screen brightness for comfort and visibility during normal use? trying to stretch battery time on a laptop? trying to set the dimness level during periods of inactivity?
