Harvesting from dead boards
If you keep scrap boards for parts, this tells you which models share the same EC, power controller, charging IC, audio codec or BIOS chip — so you know what can be pulled and where it will fit.
Laptop Motherboard Component Database
Search 39,449 repair-relevant motherboard components across 11,017 indexed laptop schematic analyses, including power ICs, charging controllers, EC/KBC chips, audio codecs and board numbers.
Dr-Bios technical index
Laptop Motherboard Component Database
Explore repair-relevant ICs, controllers, platforms and board identifiers extracted from Dr-Bios schematic analysis.
Type a part number to see every motherboard that uses it
Search KB9012 and you get every laptop motherboard in the archive documented as carrying that EC — board number, project code, CPU platform and a direct link to the schematic thread.

When your schematic was never published
Not every board has a public schematic. Look up the power controller you can read on the PCB, then find another board that uses the same part and does have one. The rail design is usually close enough to work from.
Where the data comes from
Every entry was extracted from a real Dr-Bios schematic analysis, one board at a time. Nothing here is scraped or guessed — which is why it took so long to build.
