Boards with this marking typically include voltage regulators for 5V, 3.3V, 1.5V, and 1V rails. Notebook Schematics: Detailed diagrams for common implementations (like the M540SS/M548SS series
Look for codes ending in "P" or "R" preceded by "LA-" (e.g., LA-7912P , LA-9531P ).

To find schematics, boardviews, or repair guides, you must look past the HannStar safety stamp and locate the actual design model number assigned by the hardware engineer (often companies like Compal, Quanta, Wistron, or Pegatron).
Pins 2 (+) and 4 (-). Positive wire is usually colored; negative is white or black. Move it between slots
HS-MV4-94V0-2026-01 Date: April 18, 2026 Prepared by: [Your Name/Department] Subject: Evaluation / Maintenance reference for HannStar PCB/panel assembly marked “K MV 4 94V-0”
This is a standardized UL (Underwriters Laboratories) flammability rating. It certifies that the plastics and fiberglass used in the board will self-extinguish within 10 seconds if they catch fire, preventing the spread of flames inside electronics. Pins 2 (+) and 4 (-)
