Well, that wasn’t fun.
The hardest parts BY FAR are the camera glass and bottom cover. There was a moment there where I was considering breaking the glass and just buying a new part, but eventually I got it to let go. The problem is that the glass and metal are VERY tight together, so I had to use a little precision razor to scrape away some of the metal in order to fit it in behind the glass to push it out.
The bottom section came out with some patience, but I ended up warping it with the heat gun trying to melt the glue again. That said, this is the first time I’ve used a heat gun, so YMMV.
The battery we got had a cable that wasn’t quite up to spec, so it’s probably slightly crimped. So far it doesn’t seem to be a problem.
The instructions are definitely helpful, though. Good luck!
I guess we can assume the people who tired using the aftermarket batteries were killed in the process of repairing their Surface Pro. May their valiant efforts be remembered for all the days.
I replaced the battery, but I'm still not getting an led or anything on the screen to show it's charging. What else could be the issue?
To my understanding, in order to remove the solder, you must first ADD solder to the joint. It will mix with the solder that's already there and lower the overall melting point. That that time, you should be able to use copper braid to pull the solder off the joint.
I'm about to start this project myself. I'll let you all know if it works out as expected.
