macbook pro battery x mark and no battery strength

Keep track of screws: tape, draw out diagrams, label them, etc. There are other techniques out there (wire, fishing line, etc.) and I’d advise looking into them. If you go this route, expect it to be a little frustrating & slow going - it took me around 20–30 minutes of slowly chipping away at the adhesive with only the card. Everyone calculates risk and reward differently, but for me, the risk of removing the logic board for the reward of being able to remove the battery packs with adhesive remover was too great, so I opted to only do steps 1–4, 42–53 and removed the battery with one of the cards from iFixit’s kit. As I’m a novice and this was the first difficult fix I’d ever tried, the idea of taking so many things apart - including removing the logic board - was a little scary. It is possible to cut out a majority of the steps outlined here if you’d rather not dismantle most of your laptop. The guide was great, and I recommend reading each of the steps’ comments, too. And more risks to break a plug or make a mistake while reassembling. Well, I am an engineer, that helps, but with dismantling all boards it definitely would have taken double the time. I was able to finish the work in 40 minutes, although it was the first time I opened my Macbook. I prefer this solvent to Acetone, because it’s less or not harmful to plastic (however, no warranty, just my personal experience). After removing the old pack I used Methanol to remove the glue. Beside the 10 cover screws you only have to loose 2 screws for the battery connector. If you don’t hurry, and don’t apply too much force, you will not damage anything. It may take a while, but much less time than dismantling the whole macbook. It works, if you give a little tension, pulling a pack upwards, and then work with a small blade or knife, and cut the glue stripes. It helped, that the batteries already were swollen, thus access to the glue stripes was easier. I changed the battery pack as well without removing the logic board etc.
