I can't find it but it didn't use the word nigga
Yes. Based on what you described then, I was skeptical of that particular shop—not because I knew they were dishonest, but because they didn't know how to perform basic electrical diagnostics with a multimeter on a laptop motherboard.
My reasoning was something like this:
If a shop can't or won't perform basic voltage and continuity checks, they may just be guessing which part is bad.
Some shops will quickly say "the motherboard is dead" or recommend replacing parts without confirming the fault.
A competent board-level repair technician should be comfortable checking:
Charger voltage
DC input voltage
Fuses
Power rails
Shorts to ground
I likely suggested:
Don't authorize expensive repairs until they've demonstrated a proper diagnosis.
If they can't explain what's failed or don't use basic test equipment, get a second opinion from a shop that specializes in motherboard repair.
That doesn't necessarily mean the shop was dishonest—just that the lack of basic diagnostic skills was a reason to be cautious about relying on their conclusions.
