Been through a swelled battery and then repair with this MBP already under Applecare 2 years ago. Now the lid doesn't close flush again by about 1/4". If left with power off, the lid looks more flush. But when the unit heats up, then the gap appears. Coconut Battery and the machine itself says the battery health is good. MBP operates fine in all respects but for the lid not being flush. The upper corners of the touch pad are slightly raised. Is it the battery anyway or some other issue. Taking it to the Apple Store for inspection today. Love my 15. Don't want to upgrade if I don't have to do so. Any ideas?
