Hi everyone, I recently installed windows 8 on my dell laptop. The brightness is automatically set to higher than my normal settings whenever the PC boots up. It starts from the Blue Window 8 logo screen to the Select Your Operating System screen. I'm dual-booting windows 7 and 8. When it reaches the Enter your user password screen, it goes back to back to normal settings. (I always set Brightness to lowest possible). So basically this always happens when the PC boots up, But it auto-adjusts itself to my settings after I enter my password). I installed the Ambient Light Sensor drivers for my laptop to fix the Device Manager yellow exclamation marks. But I disabled the Ambient Light Sensor service in Services.msc, but that didn't fix it ... Adaptive Brightness is also disabled.. Has anyone experienced this before? Thanks in advance for any help.
