I recently had my MBP taken to the Geek Squad to have the optical drive replaced under the extended warranty through BestBuy (which I didn't know I was getting BestBuy's warranty, not the AppleCare). When I sent it in, they replaced the bottom casing, optical drive, and the logicboard. When I got it back, I noticed that my serial number for my MBP is missing, they didn't enter the number when they replaced the logicboard. Is there a way so I can personally enter my serial number back into my MBP. I figure if I go back to BB, they will send my MBP off to the service center in Kentucky or something.
