Hey everyone,
I've also experienced these same "white spots" on my Mac Book Pro. I purchased it about a year ago and they started appearing on my screen in October. It looks like someone used their finger tip and applied direct pressure on my display. They almost form a perfect circle pattern in the middle.
I took my computer to an Apple store in Toronto and they couldn't diagnose what the issue was so they did the screen replacement under warranty.
Unfortunately, it began happening AGAIN a few weeks ago and I took it back to a store today to have a "genius" look at it. Immediately, they said that it was a result of putting too much pressure on my screen. I wondered how the heck I could have accomplished this since I thought I treated my MBP like a baby. I was using a Crumpler laptop bag to tote my baby around and according to them a combination of; all the gear I was carrying (which isn't much), the fact that it was a shoulder bag (resting on my hip when I walk), and the fact that I use one of those Marware keyboard covers together (which applies pressure from within) contributed to the pressure put on the center of my screen. And ultimately, they won't replace the screen because it's "my fault".
I'm just bugged by it because...
1) The genius I originally dealt with didn't know what the problem was so I couldn't take any measures to better protect my computer after it was repaired. I could have bought a tougher case, made sure I was more aware of what else I put in my laptop bag (although I never put that much in it initially), or just left it at home.
2) The genius (who was quite rude actually and treated me like I was stealing from him) I dealt with the second time said he saw this issue quite often but there is no warning anywhere saying that the Mac Book Pro can be succeptible to this. Geez, I have friends/family with Mac laptops that treat them like crap and have no issues like this. Also, I know people with PC laptops that are built like tanks (who spent a fraction of the money I did) and can put up with alot of day to day punishment.
3) I bought the Marware keyboard cover AT the Apple store. Why are they selling something that has the ability to damage their laptop screens?
So I hope people can read this and take the proper precautions when storing their Mac Book Pros during transport. Luckily, the spots aren't too bad, I just make sure my desktop wallpaper is dark so the spots won't be so obvious.
Sorry Apple, you just lost a point with me.
