Recently had an issue where my early 2011 MacBook Pro 15" would intermittently, never at the Genius Bar, get a pink screen and freeze up.
Although it passed the video card test after my second visit they decided to fix it. I thought it was a video card that was replaced but the invoice said logic board.
Anyhow.
After getting my macbook back I immediately noticed that when restarting it, when the start up screen appeared a pixelated bar appeared closed to the top. It eventually loaded no big deal.
The second thing I noticed was a X where the battery icon was on the menu bar and the macbook wouldn't stay on without it being connected to the charger. After doing some research and resetting the pram and smc it seemed to temporarily fix the issue. I checked the health of the battery and it was fine and charged up fine.
While recharging I noticed the battery icon would randomly have an x appear then disappear and eventually the macbook would only stay on when plugged in.
One additional issue I discovered is that after resetting the smc my macbook would no longer go to sleep when closed.
Before getting the logic board replaced the only issue I had was the intermittent pink screen lock up that really didn't happen that much.
To those of you who've had the logic board replaced did it fix the pixelated bar? I suspect either a bad logic board was installed or just a bad installation. I have an appointment at the apple bar tomorrow but am afraid the issue won't be reproduced or the issue won't show up in their tests.
