The one I’m working on has 10 different sized screws, requiring 3 different sized torx bits. The batteries in this swelled up so big they popped the screen off. It’s a little annoying that they want you to adopt something as a replacement for a traditional PC that’s only going to last as long as the buried in battery. I would not recommend fixing this hardware in the future. Like most things these days, unfortunately, throwing it away may well be the best option.
