I had to stop into the Apple Store to have them look at my MBP— it recently started shutting itself off after one or two minutes’ battery usage. The Genius looked it over, verified I had the correct firmware (apparently there was an update that fixed random shutdowns), and then pulled the battery out…to find a good-sized bulge along the bottom. WHOA. Without another word, he said, “OK, we’ll get you a new one,” and when he couldn’t find one in the back (internally identified as a “part”) he walked out to the store, pulled one off the shelf (identified as “stock”), opened the box, slapped it in, and bid me farewell with a smile.
God, I love proper customer service.
