That's what a highly integrated machine gets you. Charge circuit defective => replace entire main board, including CPU, probably memory and storage too nowadays.
No one is doing component-level repairs any more.
Not entirely accurate, its just a highly skilled bit of work that you have to work to find people that can do it. This guy does it: https://www.rossmanngroup.com
Watch his youtube channel here and you can learn how to do it yourself: https://www.youtube.com/channel/UCl2mFZoRqjw_ELax4Yisf6w
That said, in general you're right. Component level repair on multi layer pcb's with BGA or reflow soldering is... not all that economical in the amount of labor and skill and equipment involved.
I also possess a 2013 MBP with a Retina screen, proudly running well all these years later after many AAA games, overclocking, and innumerable HD repartionings. However, I broke my MBP's screen twice, and both times I called the closest Apple repair shop, and once the main "independent" repair ship in my city, and all three times the price came back as a nice, round $1000: nearly half of the original price!
So I looked around online (always had been vaguely aware of Right-to-Repair, and ifixit.org). After reading the excellent repair guide online and ordering what seemed a high-quality screen online, the repairs, which cost me no major headache or extreme difficulty, materially ended up costing around $300. Also, I want to mention that the aforementioned ifixit guide listed the highest difficulty grade to this type of repair.
So you are telling me, someone that had never engaged in computer or mechanical repairs before in his life, performed $700 of labor in just under an hour? No, the likelier answer is that Apple is simply rent-seeking in the sector of product repairs.
There is a vendor on eBay who does this, cannot recall his name.
But they will definitely desolder and replace any component wherever this is possible.
I've sent my laptop to this guy in NYC, and had a pleasant experience, even if he couldn't find my problem. (intermittent shutdowns)
I tried to stay with Lenovo, but after the endless waves of shitware, spyware and low quality hardware (!) I had to give up. Thinkpad’s great name is thanks to IBM, and perhaps, maybe, a bit of early Lenovo. Maybe.
If Lenovo is competing with anything, it’s with IBM.
I don't think this is particularly true, 2009-2012 era hardware designed/built by Lenovo/Quanta is also around in plentiful numbers.
This way I can upgrade to a new model when I feel it's time to.
