MBP 17" Screen Flicker While Charging

How disappointing is it to discover a flaw in a brand new product?
Anyway, I'm sitting here using my new MBP 17" which arrived early this morning.
I had used the battery up a bit earlier today, and am currently charging the laptop. The screen brightness is set to it's lowest visible brightness (one more down and the screen goes black).
I am experiencing a slight and intermittent flickering of the screen. At first I thought it was just in my head... Oh yeah, there are no fluorescent lights around me.
Anyway, on a whim I unplugged the power cord and the flickering immediately stopped. Plugged it back in and it started up in a minute.
By the time I finished this post the flickering stopped. What's goin on??

The screen dims slightly when under battery power...maybe the charger is bad and oscillating on and off?
Got a spare you can try?

If you have one locally why not pop in to your local Apple store and see what they have to say about it? Certainly sounds like a hardware issue and not something you will be able to fix yourself.
Also if you know any one with a spare adaptor from a fairly new MB or MBP it could be worth trying theirs' out to ensure it's not just the adaptor.

At work we had a few of the 15" models that had a similar flickering problem when the systems were first released. Strange thing, we found the flickering would only occur when the embedded (9400) GPU was being used. When we switched to the discreet (9600) GPU, the issue would go away. In our case the units were exchanged due to suspicion of a bad embedded GPU. I haven't seen the issue on any systems ordered in the past few weeks though. It potentially could be a different issue all together, but you might see if you have the same experience. Please do post what you find out with Apple.

I have a 15 inch model too and notice the flickering when using the 9400 GPU. Do you think if I were to bring it in to an Apple Store they would exchange it? Were your replacement models free from this screen flickering?

We have probably deployed about 200 of the 15" MacBook Pro systems so far, and have only seen the issue on a handful of them. Fortunately the issue was discovered when the systems were imaged and had not yet been deployed. If you are having the issue, I would recommend that you report it to Apple.
Some people online were reporting that installing the NVIDIA Graphics Update 2009 (http://support.apple.com/downloads/NVIDIA_Graphics_Update_2009) would fix this problem. The update however was only available online briefly and then was pulled without explanation.
I really don't see how this would help though as we are not seeing the issue with all systems we are receiving. I figured there must have been a bad batch of 9400's that made it to production. It is really concerning if people are seeing the same thing on the new 17" models as well.

I was using the 9400.
OH GOD I don't want to have to deal with Apple again, they TOTALLY botched my last laptop (thus the upgrade to the new 17"). Sigh. Thanks for the tip I will keep on it.
