Use the boardview’s “netlist” mode to select all GND pins. Probe between CM4_VIN and GND. If resistance is <10 ohms, there is a short. Use a thermal camera or freeze spray to find the shorted MLCC capacitor shown in the boardview.

: Look for a small code starting with "E" (e.g., E162264 ). This confirms the factory of origin and can narrow down the search on Dr-Bios or BadCaps.

: This board is frequently found in older laptops like the HP 311 , various Lenovo models , and tablets like the Essentiel B Smart Tab 8004 .

It was only a small thing, noisy and fragile in a world of algorithmic certainties. But the board's 94V-0 stamp gleamed, and Mara thought about standards—how they protect circuits and people in equal measure when followed, and how often they were only part of a promise.
