Dell Studio 1558 with AMD Catalyst Driver 13.4 or onwards in Windows 8 or Windows 8.1
I'm facing following issues since installing AMD Catalyst Driver 13.4 or onwards.
My current OS is Windows 8 Pro, Display driver: AMD 13-9_mobility_win7_win8_64_dd_ccc_whql.exe
Graphix: ATI Mobility Raedon HD 5470
1. If set Backlit brightness to level 2 for example, and after some time display turns off (turn off display after X minute) by itself, or restart the laptop; the Backlit brightness level remains same (level 2) but the actual Luminosity (Intensity of backlit) changes to something else.
2. If I decrease the Backlit brightness (Fn + F4) to level 0 (the minimum level), and if I further press the key combination (Fn + F4) to decrease Backlit brightness, it will change the Backlit brightness, but the Backlit brightness should not be changing because it already reaches to the minimum level.
