Replace Laptop Battery With Power Supply
I have an old Macbook Pro 2013 UK version, and it's broken. I have a feeling it's the charging circuit for the battery that's broken, and that everything else works fine. I'd like to have a go at fixing this myself. My first thought was that if I removed my laptop's battery, and connected an adjustable power supply in its stead, which supplied the same voltage to the board as the battery would, then I could at least get the thing to boot and run- just to confirm my theory. Then I can research the cost/method of replacing certain charging circuit components and decide if it's worth it. Does any
