Positivo SIM 3040 laptop schematic covering mainboard DASW6HMB8E0 at revision E, supplied as a 1.23 MB PDF. The DA-prefixed number follows the Quanta pattern, meaning Quanta designed the board even though it ships under the Positivo name. Use it to trace the standby and main power rails, locate the charger and EC circuitry, and look up test points when diagnosing no-power or no-display faults. Verify that the revision letter printed on your PCB matches rev E, as component values can change between revisions.
