This guide explains how NLCRC techs use BoardView files together with Sumita-style board PDFs and schematics. It is written in English for the NLCRC forum (paraphrased practice notes — not a copy of another site’s posts). 1) Identify the exact board - Read the PCB part number and revision silkscreen (and ODM markings: Compal / Wistron / Quanta, etc.). - Do not open a “close enough” BoardView. Wrong revision wastes hours and can point you at nets that do not exist on your board. 2) Open the trio - Schematic PDF: net names, IC pinouts, power trees. - BoardView: click a designator (e.g. PQ301, PU101) to highlight pads and connected copper. - Sumita / board-map PDF: printable top/bottom maps for marking test points during rework. 3) Safe probing order - Confirm adapter/battery path and main enable rails before chasing obscure signals. - On BoardView, locate the IC, then find a solid ground and the rail test point from the schematic. - Write measured voltages on the Sumita map so the next shift sees what you already checked. 4) File hygiene - Prefer checksums when we publish downloads. - Never flash a BIOS dump until board PN, chip ID, and ME/EC expectations match. Need a missing BoardView or Sumita PDF? Use Downloads → Request file, or open a BIOS/board file request. Mail-in remains available (free diagnostic, £15 return shipping if you decline repair).
