It really doesn't take more than 20 minutes to get access to the motherboard of a MacBook. Are you under the notion that you need to fully strip down the computer before being able to diagnose it? You don't. You just pop the back cover, replace the battery with a bench power supply, and start testings. You can do most tests without removing the board from the chassis. You might eventually need to get access to the other side of the board, but again it doesn't take 20 minutes to do that.
Here's a video where they remove and put back a MacBook Air motherboard in 13 minutes, on camera (https://youtu.be/Sk8kj_y32mU?si=4fUoXux_zLIGg-9B https://youtu.be/Sk8kj_y32mU?si=4fUoXux_zLIGg-9B).
I already took into account a pessimistic 50% repair success rate at a salary double what most shops pay.
- dpkonofa 3y agoSo then the parent is right. If disassembling it took 13 minutes, then they’d have 7 minutes left to reassemble and that wouldn’t involve any actual repair.
- sudosysgen 3y agoIt took 13 minutes to both disassemble and reassemble. So then you have another 20 minutes to diagnose. If you can repair 50% of boards that make it far enough that you need to dissassemble for diagnosis and then you take an additional 30 minutes to do the repair with 50% success rate, you're spending 3.6 hours per repair, which is perfectly fine if you're charging 300$. These are pessimistic assumptions too - you often don't need to dissassemble the board to diagnose it, the person disassembling the board doesn't need to be paid as much as the person doing the repair, and you'll probably have a better than 50% repair success rate.
