Hi , thanks for reading my video, I did a SP4 battery replacement for one of my SP's that was a high spec machine but was sold on eBay cheaply due to its battery expanding. I didn't know what to expect on this video so took the screen off and then remembered I could record it for anyone else for tips along the way. This isnt a how to guide, just more for someone that is about to do it and wants to see the steps I took so they can replicate. It was not too hard and I had an older SP4 with a dead board so I nicked the battery out of that. Use proper protection for yours, get a screw box to sort the different parts out if you haven't done one before. I hope it helps. If it does please subscribe..
