T510 DISPLAY Issue: Intermittent high Contrast/Brightness

[Shellz]

Hi folks - This is my first Lenovo forum submission and I will do my best to describe the problem with my laptops' video/display. I'm all ears for your suggestions.

*Issue*

The display would occassionally dip down in brightness/contrast then change up to a very HIGH contrast level on its own. The desktop icons, background image & browser images become un-sightly bright BEYOND your normal Lenovo Power Manager settings. All the white hues turn even brighter, and some hues are NOT viewable at all on certain backdrops. Usually, it resolves itself after several minutes.Then it's business as usual.

I do not believe it has anything to do with the Power Manager settings (e.g. Idle Time, brightness control, Battery vs AC power, etc.). It simply occurs on it's own then disappears. A reboot can help and so does closing the lid and re-logging into Windows. But who wants to practice that technique after paying over $1600 for a professional grade business laptop?

I found only ONE forum message that came close to reporting the problem, found in the body of a message and NOT as a subject (SEARCH:  "screen image fades as if you lose contrast")

Frequency ? - Atleast 4 times a month for the past 3-4 months since my purchase in summer 2010.

Problem occurs more often than 4 times a month. More like 10 times a month for the past 4-5 months.
