I just re-installed Windows 7 today and my screen is just too dark I can't hardly see anything. I noticed that the brightness buttons on the keyboard are not working. So I went to the Control panel→Windows Mobility Center and under Display it says that there's no display connected.

I even installed all of the Windows updates but it didn't help at all. This has happened before when I re-installed Windows but it went well after installing Windows updates but this time it doesn't work. The screen is way too dimmed. Is there any work around for this?

I have an LG R405 with a standard built in video card. Any help will be much appreciated.

The problem was the Operating System, Windows 7 Swedish. There seems to be incompatibility between the OS and my LG R405 Laptop because I installed that same OS on another laptop and it's working smoothly. The solution was to install another OS Windows 7 English and the problem was gone.
