Here’s for 5 more years
My battery was showing its age by barely holding a charge, Having swollen up cells and being 5 years old.
It was easy to take apart the components like the speakers and trackpad cable. The battery on the other hand was having slight problems getting out. Due to its age though it was more loose so that’s a plus.
When doing this repair take your time. No rush. You learn how this computer works and appreciate it. You also save some money so you can get a sandwich or something you want, idk :) (p.s get a kit if it’s your first time with batteries!)
