Help With Screen Brightness
(12 posts)
Woow, thank you all for your fast answers...
My battery settings is "Balanced", and from the power options the brightness is set for battery (for ex: about 30%) and for plugged in (100%).
But the problem is: My laptop isn't distinguishing between plugged in and battery (what i mean is: brightness stays the same 50%), but I can increase/decrease using the "FN" option...
I was thinking my laptop lacked a driver? If yes, what should i search for?
Thanks again,
Ara
Do you have "Lenovo Energy Management" pre-installed in your computer? if you do, try to change those settings, or directly try to uninstall it.
If you don't (or if you can't solve the problem) try to install the latest version from here (filter "Power Management" and "Windows 7"):

If nothing works tell me and I'll think of another solution.
Hello Ruja,
What did you mean by: "try to change those settings" about Lenovo Energy Management?
I love Lenovo's Energy Management and it's up-to-date, so it's impossible to uninstall it :)
The problem isn't from the Energy Management, it is from the more power options! If i change brightness (for ex: for Balanced, and from Energy Management, it is placed Balanced, it won't change (the brightness slider down doesn't affect the brightness too!) So I'm guessing its a Windows 7 problem?
While when I press "FN" and button up (brightness up) button down (brightness down) the laptop changes the brightness and shows Lenovo's box as it fills and empties when increasing or decreasing the brightness....
I also formatted my laptop after installing Windows 8 a month ago (cause I didn't like it; and Lenovo lacked many drivers), and reinstalled my Lenovo's original Windows by the recovery disks I created via OneKeyRecovery when I got my laptop. The brightness was working before the format!!
Thank You,
Ara
@Ara I suspect Lenovo Energy Management might be interfering with Windows 7 power settings, and prevents Windows from changing the brightness when you move the brightness slider in the Power Settings, or when you plug/unplug your computer to AC. That's why pressing "Brightness Up" and "Brightness Down" keys shows the Lenovo's box, instead of just changing the brightness with no boxes showing, as a clean Windows 7 installation would do. I would recommend to uninstall it and check if it works this way. You can always install it again if you like, maybe by uninstalling/installing the problem is solved.
I don't know how Lenovo Energy Management works, so I don't know which settings are available, but I'm usually against all this manufacturer pre-installed software.
Thank You marks100 and Ruja.
@marks100, i tried windows + X and it opened the Windows Mobility Center...
From it i tried to reduce/increase brightness but didn't affect!
And thank you for introducing me to this box! It's a great feature I didn't know!
@Ruja, now i'll try uninstalling the Energy Management...
Thank You Again,
Ara
