I don't know why, but from time to time windows moves something and brightness just resets to lowest point. I can adjust it with the fn+ keys but goes low again.
Its the autodim, but when dim and move the mouse or use keyboard it wont back brightness, stays dimmed.
What i did was to unistall video driver, osd and reinstall and everything worked ok. but now i doesnt. I have unistalled command center, video and osd and reinstall and not working.
But if i dont install command center, the display brightness works as it should, but can't turn off the keyboard.
Any help would be really appreciated.
Solution:
So, after understading power features in windows 7 (yeah until now)
So the Auto Dim is not for activating the dimming of the screen after a determined time.
The Auto Dim is for dimming the screen depending on the ambient light (like cellphones and tablets), but the laptop doesnt have this sensor, so i think its value its 0 light so it dimmed to minimun state.
Putting it off, sovled the issue.
After all this years having problems with this!!!!

Which settings are you talking about??
I mean... the brightness resets to the minimum, but can use the fn+f4 to get it to maximun but after a while it will go again to minimum.
Command Center, Screen Bightness low automatic.
