My 1 year 2 month old 15" intel MBP will randomly shut down with no warning on battery power (no problem when plugged in). Is this that RSS (random shutdown syndrome) that they had on the class action lawsuit on the early macbooks? I read that a bad heat sink shorts out or something? Anyone else have this problem? I have a hairline crack on the battery, but no damage to the computer anywhere else. Do you think Apple will even give me the time of day with it being outside the warranty?
