Gave my wife's battery new life
5 - 10 minutos
The old battery was not holding a charge like it used to. She was lucky to get 2 or 2.5 hours out of it, where it once was 5-6 hours with the screen dimmed down halfway.
Easy. I already had the tools I needed, and it went like a breeze.
I may have used the wrong guide, but the guide said to use a Y1 screwdriver and I actually needed one size over, either Y2 or Y0, I forget which. The bit that was specified was a bit big, I needed a smaller bit. Luckily it was right there in my 54-bit driver kit.
