That capacitor I missed caused a 3 hour redo on a motherboard repair
I was working on a 2015 MacBook Pro board at my bench in Denver last Tuesday. Everything tested fine but the power rail was sitting at 11.8V instead of 12V. Chased dead traces for two hours before I spotted a tiny cracked cap near the ISL6259 that I swore I checked. Swapped it out and voltage snapped right to 12.0V. Has anyone else had a tiny part like that wreck their whole afternoon?

Honestly, "chased dead traces for two hours" hits close to home. I keep a magnifying lamp right at my bench now just for those tiny cracked caps near the ISL6259.

@west.alice brought up the magnifying lamp - do you use the cheater glasses too or just the lamp? I got a set of those after missing a resistor on a T2 board once. Never looked back.
What was the specific location of that cap you thought you checked? I always assume the ISL6259 area is clean but you just proved me wrong. Makes me wonder if I've blown past something similar without catching it.
