The PDF hadn't just told him what to check; it taught him how to think. It explained that the power wasn't reaching the "heart" of the board because the "gatekeeper" was broken. A fuse didn't blow for no reason, though. The guide warned him: “Never replace a fuse without checking for a short circuit downstream. A new fuse will blow instantly, and you risk damaging the charging circuit.”

- No power, no LED → Check DC-in MOSFETs, protection IC, main fuse.
- Power on, no display → Measure VCC_CORE, check RAM_VTT, reflash BIOS.
- Short on 19V rail → Inject 1V/2A and use thermal camera to find the shorted capacitor.
- Overheating IC → Replace buck converter controller or filter caps.
