A few days ago, I purchased a 17" Macbook Pro with Apple Care for a few more months. Was coming from a trusted member, didn't check the serial out online. Get home and check it, only to find there's no Apple Care tied to the device, just a 1 year warranty (that expired years ago). Called Apple and they tell me the Apple Care was never registered, just purchased. They said I could register it to the 17" but it would have already expired (>3 years since original purchase). Now I seem to have a sealed Apple Care for 15" or 17" laptops, but have no idea what to do with it. Searched around here on the forums, and read there were issues with selling it on eBay or Amazon as someone could activate the serial without opening the package, and then claim it was already used to get a refund from Paypal/Amazon/etc. Additionally, some threads stated you had to have the original proof of purchase of the Apple Care to activate it. Can anyone shed some light on these two dilemmas? Am I stuck with a $225 piece of paper that has no value, in addition to a laptop with no warranty?
