Ipkbl-sr 35w Schematic ((install)) -

The IPKBL-SR is a motherboard typically found in Dell OptiPlex 3050 Small Form Factor (SFF) or Micro desktops, supporting Intel 6th and 7th Gen processors with a 35W TDP (Thermal Design Power) limit for the Micro variant. While official board-level schematics are proprietary and rarely released by Dell, technicians often rely on Dell's support manuals for pinouts and diagnostic codes. The Ghost in the Solder

1. IPKBL-VM Schematic: This is the "value micro" variant. 90% of the power distribution and PCH pinout is identical. Only the audio and I/O ports differ.
2. IPKBL-SR 65W Schematic: The layout is identical, but the VRM has additional phases. You can still use 90% of the document to trace probe points, connectors, and BIOS pins.
3. Boardview for S300/S500 series: Search for Lenovo AIO boardview S500-22. The form factor matches the 35W cooling solution.

5. Typical Waveforms (Test Points)

• Primary Switching MOSFET:
