So my out of warranty Mid-2014 15" retina MBP has been getting thicc recently to the point that the trackpad is now extremely hard to press. I called Apple Support, and based on what I told them, they suspect (like I do) that it was due to swollen battery. In order to send the laptop in, they requested that I paid them $630+ first to process the repair. They literally just sent an email, requesting payment with zero detail, then they will send me the box to ship back laptop upon me paying the bill first. This is without them seeing my laptop first, without any diagnostics, and no itemized bill for what I am paying for. Obviously I took issue with this and called them again, then they told me the estimate they quoted is from the phone support person who deemed that is how much fixing my laptop requires. (This time, they confirmed, it's the swollen battery). I asked them to schedule me for a genius bar appointment instead. Now, I have a couple questions: A) Is $630+ the going rate for battery replacement at Apple nowadays??? It seems outrageous. Sure, I guess they might have to replace the entire bottom casing due to the bending metal, but don't I get a say for what I want to have replaced or not? B) How hard is it to do a DIY battery replacement? Is it safe to handle swollen battery? If it's not safe, what's the going rate for non-Apple repair shops?
