Hello,

I have a old Dell Precision M4500 with a Nvidia FX880M and a I7 620M. when i turn on the system the screen works fine, but after starting windows the screen is dim (in safe mode the screen works). i can see a little bit when i shine on it with a flashlight. I use windows 7 ultimate. i already replaced the ambient light sensor, en updated the bios to version A16.

I could find nothing that works for me on the internet.

I hope someone could help me with this.
