lol this is becoming a daily occurrence... or maybe it already was and I just wasn't paying attention.  Either way it's funny, but in a sad and concerning sort of way.

Screen won't turn on

Customer takes it to an Apple authorized repair place

They tell him it's due to a blown fuse and the whole main board needs to be replaced

Turns out it was actually just a bad capacitor and took about 5 minutes to fix

That second last line is the real winner here though.  There's a lot to unpack in that "diagnosis" lol

Putting aside the fact that they should have been able to tell whether or not it actually was the fuse successfully, the bigger issue here is their recommendation that, under the assumption that the fuse was the issue, the whole board needs to be replaced.  Is the whole purpose of a fuse not to be an easily replaceable sacrificial component that protects the rest of the device!?

Again, I hate to fathom how much consumer money is wasted and how much unnecessary e-waste is created by their policy of grossly overzealous and heavy-handed fixes that refuse to acknowledge the concept and existence of parts smaller than the whole motherboard.  I joked in the comments that to Louis, a high resolution component-level repair is changing out individual capacitors, and to Apple, it would seem that digging down beyond just "buy a new laptop" to the level of "just replace the whole motherboard" is delicate and nuanced surgery, but it's really not a joke, it's a reality and a problem.  It's the same issue Linus had with his iMac Pro back during that whole incident.  They said he'd need to replace the whole machine, and even after tons of effort, was only able to dig down to the level of replacing the entire board, including memory, CPU, etc. despite the fact that these are separate, socketed components and could easily have been left out.  Apple has all these environmental programs involving recycling, avoiding certain materials, using green energy, etc. but frankly in the context of their approach to repair, it seems like these are nothing more than a front or a PR stunt.  It they actually cared, they would make more of an effort to avoid throwing out and replacing more than is necessary.
