Topstar C46 schematic, revision A, delivered as a 1.33 MB PDF. Boards from the Topstar ODM appear in many white-label laptops, so the C46 marking on the motherboard is the key to matching this document. Use it to follow power rails from the adapter input onward, locate test points and diagnose shorts or missing voltages. A companion power-on sequence sheet exists for C46 and C48, which complements these pages. Check the revision on your PCB before relying on values.
