I also have a brand new MacBook Pro, 2.5 GHz, all of 2 1/2 weeks old. It exhibited the same vertical stripes as shown in this picture (took one of my own). Like others reported in this chain the problem went away after closing cover, waiting for system to sleep, and waking it up again. At the time this happened I had just been using the system for normal meeting work, note taking, Powerpoint, Email, web browsing. No use of any other peripherals, special graphics, external devices, etc. I have Parallels installed but have not yet needed to fire it up (for which I am thankful).
Other questions / answers:
1. How often does it occur? Does it occur reliably?
Just started. During normal use. Cleared after sleep / wake cycle.
2. Does it resolve if you perform a specific action? What is this action?
Closed the lid for 45 seconds, waited for "sleep" light to flash, on reopening, it was ok
3. Does it always resolve by performing this action?
Too soon to tell, first time this weird thing happened.
4. Is the machine plugged into AC when the problem occurs?
Yes
5. Can you cause the problem to occur by performing an action?
Not clear.
6. Is your display glossy or matte?
Gloss
7. What type of video graphics hardware does your machine have? How much VRAM?
GeForce 8600M GT, 512 MB RAM
8. When did you purchase your computer?
June 23, 2008
9. Do you have a photograph of the defect? If so, please post a link.
Yes, not posted but EXACTLY like others on this thread.
1) Do you have any virtualization software installed (VMware, Parallels)?
Parallels, never used except as part of install checkout 2 1/2 weeks ago.
2) What brightness setting do you typically use for the display? (Full, 7/8th, etc.)
I think you may have something there. When I first got the MBP the brightness Full brightness, auto-adjust is ON
3) Under System Preferences -> Energy Saver -> Options, what is your setting for:
Automatically reduce brightness of the display before display sleep (ON or OFF)
ON
4) Under System Preferences -> Display , what is your setting for:
Automatically adjust brightness as ambient light changes
ON
