My MacBook Pro is at the Apple Store getting its third logic board and, strangely, I’m okay with that. I first noticed a problem with the right USB port dropping off when accessing a USB Drive or recording. After some diagnosis at the Apple Store, they figured the logic board needed to be replaced. So I turned it in and a few days later got the cal to pick it up.
When I showed up, a very nice Apple Genius explained the new board had a small defect for the onboard battery (the one that keeps time when you shut it down). They had already ordered a replacement but told me to take the Mac home until the new one showed up. Sure enough, they now have the replacement board and are setting things right. This was a great consumer experience. Not because the board was wrong but because they cared enough to figure that out and get the situation resolved even before I knew about it.
As an aside, if you ever get a new logic board, make sure to de-authorize your iTunes account before the replacement. The logic board has the serial number on it so to the rest of the world it is like you got a new computer. It looks like I’m also going to need to restart the Time Machine.
