Hi, I am facing 2nd issue with my newly purchased T430. This issue mostly happens in the battery mode. For the past 10 days I was not quiet sure but yesterday while I was working on some of my photogrpahs and as I was switching from very bright image to a dark image I can see the display reducing its brightness automatically in the darker image with few flickers. I tested it again and again just to make sure. I noticed that as I return back to a bright image the screen brightness gradually increases, infact to an extent that you feel like reducing the screen brightness manually.
Has anybody faced this issue. If yes please share a solution to this problem or is this a hardware issue ?
I read in one of the threads for unchecking Dynamic Brightness Control in lenovo power manager which by the way in my case are all unchecked.

Have your drivers been updated?
What operating system are you running?

Yes, I updated every thing from system drivers to windows. I chekced this using the lenovo system manager which I belive checks for any updates avaiable. I have also updated my BIOS from 1.16 to 2.51.
I am using Windows 7 Professional.
Please let me know if you need any further information. Please help me resolve this issue.

Try running your system in safe mode to see if this issue still persists.
