Last updated: April 2026 – Revision analysis based on typical embedded HPC standards. Actual schematic details may vary by manufacturer.

The OSAMU2-DIS-KB-HPC MV-MB-V1 is a motherboard revision primarily found in the HP 15-d series (e.g., HP 15-d035dx) and some HP 255 laptop models. It is commonly associated with hardware configurations featuring AMD processors and discrete graphics. Core Motherboard Specifications Manufacturer/OEM: Typically manufactured for HP laptops.

Platform: Often based on the AMD Beema or Kabini APU platform, integrated directly into the board. Key Integrated Circuits (ICs):

Embedded Controller (EC)/KBC: Often utilizes the ITE IT8518E chip. BIOS Chip: Generally found at location U12 on the board. Datasheets : Include datasheets for key components

Graphics: Designed as a "DIS" (Discrete) board, meaning it features dedicated graphics hardware, though some technicians perform "DIS to UMA" (Discrete to Unified Memory Architecture) conversions to bypass failing GPU chips. Schematic and Repair Details

The schematic for this board is a critical tool for technicians diagnosing power-on or display failures.

Common Issues: Technicians frequently use this schematic to troubleshoot "No Display" or "Power but No Screen" issues. Diagnostic Checkpoints:

BIOS Verification: Checking for activity on the BIOS chip pins using an oscilloscope.

RAM Rails: Confirming 1V and 3V power signals are present in the RAM area. Num Lock (WS2812 or simple GPIO)

GPU Troubleshooting: Because these boards use integrated AMD chips, display issues often require chip reballing or specialized heating/pasting if the internal processor fails. Technical Resources
