D10-240p1a Schematic

The HP D10-240P1A is a specialized 240W Power Supply Unit (PSU) frequently found in HP’s Small Form Factor (SFF) desktop lines, including the HP Elite 8000, 8100, 8200, and 8300 series. Because these units use proprietary connectors rather than the standard 24-pin ATX layout, finding a schematic or repair guide is crucial for technicians looking to restore older systems.

What device is this from?

The D10-240P1A is a 240-watt internal power supply unit (PSU) used primarily in HP small form factor (SFF) desktop computers, such as the HP Elite 8000, 8100, 8200, and 8300 series, as well as the ProDesk 600 G1 SFF. D10-240p1a Schematic

  • Operational Amplifier (e.g., LM741) for signal amplification.
  • Passive Components: Resistors (1–10 kΩ), electrolytic capacitors (10–100 µF), and coupling capacitors (0.1–1 µF).
  • Voltage Regulator (e.g., 7805) to stabilize DC supply.
  • Semiconductor Diodes: For rectification or protection.

He pulled the heavy linen schematic from the flat-file drawer. The diagram depicted a power distribution unit, yes. 240 volts, single phase, 10 amps. But the routing was wrong. Power flowed into a sealed chassis labeled "AUDIO RETURN / NULL MODULE" — but no output lines. Just a single, thick trace that terminated at a symbol Leo had never seen: a small, open circle with a jagged line through it, like a cracked egg. The HP D10-240P1A is a specialized 240W Power
