RAR with a PDF schematic for an HP board code-named Brittle, a 13-inch platform, with Wistron board number 15256-1. Wistron uses this five-digit dash-revision numbering on boards it builds for HP, Dell and others. Open it in any PDF reader to follow power rails, the charger and EC circuits, and signal paths when diagnosing no-power or no-boot faults. The name gives no exact HP model, so check the 15256-1 marking and revision on your PCB before relying on the drawings.
