I have a Macbook Pro 13" 2015 that I bought in 2016. Of course the warranty just ended and I recently noticed serious warping. If I try to type with the internal keyboard it rocks up and down. The reason I didn't notice is because I plug another monitor into it via HDMI and every time I finish starting up I close the lid. Is this a battery issue or is my logic board warping because I leave it closed most of the time? It sounds like sand grinding when I push down on the metal area near the trackpad. I keep good care of it so I am not sure why this is happening. Also is it possible to remove the hard drive on these? Finally what parts do they replace when the battery/logic board goes crazy? I use my MBP for work so I need the files on the drive to work with.
