The identifiers E89382, MV-6, and 94V-0 do not refer to a specific laptop or device model, but rather to the raw manufacturing standards of the printed circuit board (PCB). To find a functional schematic, you must identify the ODM (Original Design Manufacturer) motherboard code, such as "MBX-XXX" for Sony or a specific part number for HP. Decoding the Board Markings
These labels are often mistaken for the model number, but they provide different information:
E89382: This is a UL (Underwriters Laboratories) file number belonging to HannStar Board Corp, a major Taiwanese PCB manufacturer. It only identifies who made the physical board, not the circuit design.
94V-0: This is a flammability rating (UL 94), indicating the board is fire-retardant and will self-extinguish within 10 seconds.
MV-6: This is a HannStar project or material code. While it narrow down the era, many different motherboards for various brands (HP, Sony, Dell) use this same board base. How to Find Your Specific Schematic
Because "MV-6" is used across dozens of different laptop models, you need a more specific identifier to find the correct PDF. Look for these markings elsewhere on the board:
HP Laptops: Search for a "Spare Part" number (e.g., 682040-001) or a motherboard model like ProBook 4740s.
Sony Vaio Laptops: Look for a code starting with MBX (e.g., MBX-267).
Lenovo Laptops: Search for the FRU number or a platform name like "Iris BSW MB". Potential Sources for Downloads

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 mv-6 94v-0 schematics
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 E89382 MV-6 94V-0 designation refers to a widely utilized laptop motherboard manufactured by HannStar Display Corporation. While the sequence "E89382" often appears as the primary identifier, it is actually a UL certification number for the PCB manufacturer, while "MV-6" and "94V-0" denote the board's technical revision and safety rating. The identifiers E89382 , MV-6 , and 94V-0
Understanding the schematics for this board is critical for technicians performing chip-level repairs on consumer laptops from brands like HP, Acer, and Sony. Deciphering the Markings
E89382: This is the UL File Number assigned to HannStar, indicating the board meets specific safety standards.
MV-6: This identifies the specific design revision of the motherboard. Common variations include MV-4 and MV-7, which may have different port layouts or component placements.
94V-0: A flammability rating from Underwriters Laboratories (UL). It signifies the PCB material is fire-resistant and will self-extinguish within 10 seconds during a vertical burn test. Common Applications and Devices
The HannStar E89382 MV-6 board is most frequently found in laptops produced between 2014 and 2016. Major compatible models include: Hannstar j mv 4 94v 0 schematics

Searching for schematics using the code E89382 MV-6 94V-0 can be tricky because these markings usually identify the manufacturer of the bare circuit board rather than the specific device or electronic circuit design. What these markings mean:
E89382: This is a UL (Underwriters Laboratories) file number assigned to Kuang Hung Electronic Co Ltd. It indicates who manufactured the physical board.
MV-6: This is often a specific model or material designation used by that manufacturer. The Hard Truth About "MV-6 Schematics" If you
94V-0: This is a standard flammability rating, indicating the plastic on the board is self-extinguishing. How to find the actual schematics:
Because these numbers appear on many different types of electronics (from monitors to power supplies), you need to look for the Mainboard Model Number. Look for other printed text on the PCB that follows patterns like:
If you search for "e89382 mv-6 94v-0 schematics", you will likely hit a wall. You will find forum posts from other people asking the same question, or links to Chinese manufacturing directories.
Why? Because these numbers describe the physical blank board, not the electronics placed on it.
Imagine buying a blank sheet of paper with "120gsm, A4, Acid-Free" stamped on it. That tells you about the paper, but it doesn't tell you the novel written on it. The schematic is the novel; the 94V-0 stamp is the paper quality.
In the world of electronics repair and printed circuit board (PCB) manufacturing, surface codes are everything. If you have landed on this page, you have likely scanned a green or blue circuit board and spotted a silkscreen sequence that reads: e89382 MV-6 94V-0.
At first glance, this looks like a random password. However, to a trained eye, this string is a roadmap. It tells you who made the board (or at least the raw laminate), what safety standards it adheres to, and a revision number. But the holy grail—the schematics—remains elusive.
This article will break down every component of the "e89382 mv-6 94v-0" marking, explain where these boards typically come from, and guide you on how to locate, read, or reconstruct the schematics for devices bearing this code.
If you are searching for "E89382 schematics" on Google and coming up empty, you are not doing anything wrong.
The manufacturers of these boards do not publish "Service Manuals" for the internal components of power supplies. They typically only offer a "Board Level" repair guide, which instructs technicians to simply swap the whole board rather than repair the component level.
MV likely stands for "Main Version" or "Multi-layer Version." The 6 suggests this is the sixth revision of that board series.MV-6 schematics, you cannot use MV-5 or MV-7. Even minor revision changes (a moved resistor or a changed capacitor value) can render the older schematic useless for troubleshooting.
