The identifiers E89382, MV-6, and 94V-0 do not refer to a specific device model, but rather to safety and manufacturing standards found on various Printed Circuit Boards (PCBs). Because these markings are generic, a "schematic" for them does not exist; instead, they represent the "DNA" of the board’s construction. Understanding the Codes
E89382: This is a UL (Underwriters Laboratories) File Number. It specifically identifies the manufacturer of the raw PCB laminate or the factory that fabricated the board. In many cases, E89382 points to KUNSHAN WANXIN ELECTRONICS CO LTD, a Chinese circuit board manufacturer.
MV-6: This is often a manufacturer's model or type designation for the specific composite material used in the board's layers.
94V-0: This is a UL 94 flammability rating. It indicates that the plastic material on the board is self-extinguishing within 10 seconds during a vertical burn test, signifying it meets high safety standards for electronics. The Challenge with Schematics
Because these codes are stamped by the board fabricator (the people who make the "green board") and not the electronics designer (the people who decide where the chips go), the same markings can appear on thousands of different devices—from laptop motherboards and monitors to power supplies and LED drivers. How to Find the Actual Schematic
To find a functional circuit diagram, you must look for the Manufacturer’s Part Number (MPN) or the Chassis Number, which is usually silkscreened in white ink elsewhere on the board. Common places to look:
Laptop/PC: Look for a string like BA41-XXXXX (Samsung), DA0XXXXX (Quanta), or LA-XXXXP (Compal).
Monitors/TVs: Look for labels like BN44-XXXXX (Samsung) or EAX6XXXXX (LG).
Power Supplies: Look for a brand name and a model number like LRS-350-12.
Once you find that specific alphanumeric string, searching for "[Model Number] schematic PDF" is far more likely to yield a result than searching for the UL safety codes.
The markings E89382, MV-6, and 94V-0 are standard PCB manufacturing codes rather than a specific motherboard model number. They identify the physical board material and the manufacturer, HannStar Board Corp, a major Taiwanese supplier that produces boards for brands like HP, Dell, ASUS, and Sony. Breakdown of Markings

Because these boards are used in dozens of different laptop models, a schematic for "E89382" does not exist in a single form. To find the correct schematic, you must identify the ODM (Original Design Manufacturer) platform name printed elsewhere on the motherboard. Common platform names associated with this PCB include: HP ProBook 4740s / 4540s HP Envy series Sony VAIO (MBX series) ASUS Vivobook / X-series Where to look for the true model number:
Near the RAM slots: Look for codes like DA0R33MB6E0 (Quanta) or LA-8241P (Compal).
Under labels: Peel back any black plastic or white stickers to reveal etched platform names.
Laptop Model: If the board is still in the chassis, use the HP Support Community or similar manufacturer forums to match the laptop's serial number to its motherboard platform.
Do you have the laptop model number or any other alphanumeric codes printed on the board (e.g., starting with "LA-", "MBX-", or "DA0-")? Hannstar J Mv 6 94v 0.pdfl - Facebook
