PDF schematic for an HP Compaq laptop on Quanta board DA0UW3MB0000, written as DAOUW3MB0000 in the name, with C3A and 0902 likely the revision and a date code. The archive is a 1.21 MB RAR. Quanta uses the DA0 prefix followed by the project code, here UW3. Use it to trace supply rails, check signals and locate components when diagnosing shorts or no-power faults. Confirm the code and revision on the PCB match before trusting the values.
