Rant: I used to spend hours on one machine, now I just swap parts

Back when I started at a shop in Austin, my whole process was about deep diagnosis. I'd spend a whole afternoon with a multimeter, hunting for a bad capacitor on a motherboard or a short on a power rail. It felt like real detective work. About three years ago, the math just stopped adding up. A client with a five year old laptop came in with a no-power issue. I quoted two hours of labor at $85 an hour to find the fault, plus the part cost. They could buy a decent refurb for less. Now, my first move is almost always a known-good swap. Got a weird boot loop? Swap the RAM first. No display? Try a different screen. If the swap fixes it, I order the part. If not, I move on. It's faster for the client and keeps my bench clear. I miss the puzzle sometimes, but the job changed. Has anyone else shifted to this swap-first method to keep up?

Parts changers who panic" is too real, I feel seen. My diagnostic skills peaked at finding which USB port my phone was plugged into. The deep dive just isn't in the budget anymore.

Can't even find the right USB port half the time.

Forget the client cost, the real loss is training new techs. They never learn how a circuit actually works, just how to swap boxes. We're creating a generation of parts changers who panic when a simple swap doesn't fix it. The diagnostic skill is dying on the bench because the business model killed it.
