. It indicates the board's substrate material—usually FR-4 fiberglass-reinforced epoxy—meets the highest vertical burn safety standards: Self-Extinguishing: The material stops burning within 10 seconds after a flame is removed. No Flaming Drips:
It will not release burning particles that could ignite other components or materials (like the laptop's plastic casing). Reliability:
This rating is standard for consumer electronics to ensure they do not become a fire hazard during a short circuit or overheating. Repair & Schematic Use
Finding a specific schematic for a board labeled e89382 mv-6 94v-0 can be a bit of a treasure hunt. If you are staring at a dead monitor, a flickering TV, or a non-responsive industrial control board with these markings, you aren't actually looking at the model number of the device—you’re looking at its safety and manufacturing credentials. Decoding the Label: What "e89382 mv-6 94v-0" Actually Means
Before you scour the internet, it is important to understand that these numbers are often "red herrings" in the world of repair. e89382 mv-6 94v-0 schematics
E89382: This is a UL (Underwriters Laboratories) File Number. Specifically, it is assigned to the manufacturer of the raw PCB (Printed Circuit Board) material, not the company that designed the circuit. In many cases, this number traces back to Kuang Hwa Industrial Co., Ltd. or similar board fabricators.
MV-6: This is likely the manufacturer’s internal code for the specific type or "recipe" of fiberglass and resin used to make the board.
94V-0: This is a flammability rating. It indicates that the plastic/fiberglass material will self-extinguish within 10 seconds during a fire test. Almost every modern electronic board carries this rating.
The Bottom Line: Searching for "e89382 mv-6 94v-0" is like trying to find the blueprints for a house by searching for the brand of the bricks. Thousands of different devices use boards made by the same factory with these exact markings. How to Find the Real Schematics
To find a functional schematic or service manual, you need to locate the Manufacturer’s Part Number (MPN) or the Chassis Number. Look for these identifiers on the board instead:
Silkscreened Model Numbers: Look for white or yellow text printed directly on the board that looks like BN44-XXXXX (Samsung), EAX-XXXXX (LG), or 715GXXXX.
The Sticker Barcode: Often, the most accurate identifier is on a small white sticker with a barcode. This usually contains the specific revision of the board.
The Device Model: If you can't find a number on the board, search for the model number of the device it came out of (e.g., "Dell U2412M monitor service manual" or "LG 42LN5400 power board schematic"). Common Devices Using This Board While the code is generic, it is most frequently seen on:
LCD/LED Monitor Power Boards: Specifically older Dell, HP, and Acer monitors.
Power Supply Units (PSUs): Often manufactured by Delta Electronics or Lite-On.
Small Appliances: Control boards for microwaves or treadmills. Troubleshooting Without a Schematic
If you cannot find the exact schematic, don't give up. Because these boards are often standardized power supplies, you can perform "blind" troubleshooting:
The "Bulged Cap" Test: Look for electrolytic capacitors with domed or leaking tops. These are the #1 cause of failure on boards marked "mv-6 94v-0."
Check the Fuse: Locate the component labeled F1 or PF1. Use a multimeter to check for continuity.
Identify the IC: Look at the main 8-pin or 16-pin chip on the board. Search for the datasheet of that specific chip (e.g., "LD7575 datasheet"). The datasheet will usually provide a "Typical Application Circuit" which is often 90% identical to the board in your hand.
Stop searching for e89382 mv-6 94v-0 and start looking for a string of letters and numbers near the transformer or the edge of the board. That is the "social security number" of your PCB that will lead you to the schematic you need.
Do you have a photo of the board or the model number of the device it came from? I can help you identify the specific chassis.
The identifiers E89382, MV-6, and 94V-0 are commonly found on printed circuit boards (PCBs) manufactured by HannStar Board Corp, a major Taiwanese electronics producer. These markings are frequently mistaken for specific motherboard model numbers, but they actually refer to safety certifications and the raw PCB material rather than the layout of a specific device. Decoding the Identifiers
E89382: This is a UL (Underwriters Laboratories) file number assigned to HannStar Board Corp. It confirms the manufacturer has met specific safety and quality standards. If you cannot find the schematic, deduce it
94V-0: This is a UL flammability rating. It indicates that the plastic material of the PCB will self-extinguish within 10 seconds during a vertical burn test and will not drip flaming particles.
MV-6: This is a specific raw material or internal series code used by HannStar. It is often found on boards used in HP ProBook 4740s and HP Envy laptops. Finding the Correct Schematics
Because these markings are used across hundreds of different motherboard designs, searching for "E89382 MV-6 schematics" usually leads to dead ends or generic repair guides. To find the actual schematic for your device, you must identify the Platform ID or Motherboard Part Number.
Locate the Platform ID: Look for a different string of text on the board, often near the RAM slots or the edge of the PCB. For boards with the "MV-6" mark, common platforms include: Rocky_Intel_MB (often used in HP ProBook 4740s). G72 or Quanta series codes.
Search by Laptop Model: If the board markings are unclear, searching for the schematic of the laptop model (e.g., "HP ProBook 4740s schematic") is significantly more effective than searching for the HannStar UL number.
Schematic Repositories: Once you have the platform ID, you can often find the PDF on specialized repair sites like VLab or BadCaps. Usage in Troubleshooting
If you successfully obtain the schematic for the correct platform, it will allow you to:
Trace Power Rails: Identify where 19V, 5V, or 3.3V power is lost.
Identify Components: Locate the exact values for burnt resistors or capacitors.
Voltage Injection: Safely apply voltage to a line to find shorted components. Hannstar J Mv 4 94v 0 E89382 Schematics

The E89382 MV-6 94V-0 designation does not refer to a specific motherboard model, but rather identifies the manufacturer and physical characteristics of the printed circuit board (PCB). Understanding the Identification Marks Given these details, let's craft an interesting narrative:
To find useful schematics, it is critical to distinguish between these manufacturer codes and the actual device platform:
E89382: This is a UL file number registered to HannStar Board Corp, a major Taiwanese manufacturer that produces raw PCB panels for various brands.
MV-6: This indicates the flammability rating and material specification of the board, often used by HannStar to denote a multi-layer board meeting specific safety standards.
94V-0: This is a standard UL flammability rating, signifying that the plastic material on the board is self-extinguishing. Common Devices Using This Board
Because HannStar is an original equipment manufacturer (OEM), these marks appear on boards for multiple laptop brands. Based on technical community reports, this board is frequently found in:
HP Systems: It is often identified as part of the HP Envy or ProBook 4740s series.
Acer Systems: Used in several Acer Aspire E5 series models, such as the E5-571.
Sony & Samsung: Occasionally appears in Sony Vaio and Samsung NP270 laptops. How to Find the Correct Schematics
Because "E89382" appears on thousands of different board designs, you cannot use it alone to find a schematic. Instead, look for these specific identifiers on the board's surface:
Platform Codes: Look for codes like DA0VM7MAB6E1 (Quanta), LA-B161P (Compal), or 6050A... (Inventec).
HP Part Numbers: Search for a "Spare Part Number" (e.g., 123456-001) or a "Product ID" found on a sticker in the battery compartment or under a RAM door.
Schematic Repositories: Once you have the platform code, you can search for the PDF or Boardview file on specialized technician sites like the HP Support Community or VLab.
Can you find any other alphanumeric codes printed in white or gold ink on the motherboard, such as one starting with "DA0", "LA-", or "MBX"? need bios of hsb j mv-6 94v-0 e89382 - HP Support Community
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.
