To find a better schematic for an HSB J MV-6 94V-0 E89382 board, it is important to understand that these markings identify the manufacturer of the raw circuit board (HannStar) rather than the specific device or laptop model.
The markings "HSB J MV-6 94V-0 E89382" are standardized safety and manufacturing codes:
E89382: The UL (Underwriters Laboratories) file number for HannStar Board Corp, the company that fabricated the physical PCB.
94V-0: A flammability rating for the plastics used in the board.
MV-6: A manufacturing revision or specific laminate material code used by HannStar.
Because HannStar manufactures boards for many brands, this same number appears on hundreds of different laptop models from HP, Acer, Sony, and Medion. To find the correct schematic, you must find the OEM model number silkscreened elsewhere on the board. 🔍 How to Find the Correct Model Number
Searching for "E89382" usually leads to dead ends. Instead, look for these specific formats on your board: 1. For HP Laptops (Most Likely)
Look for a white sticker or white text on the PCB that looks like: SPS Number: e.g., 712345-001
HP Part Number: e.g., DA0R33MB6E0 (Quanta) or 6050A2493101 (Inventec).
Common HP models using this board include the ProBook 4740s and ProBook 640 G2. 2. For Sony VAIO Look for a code starting with MBX: Example: MBX-247 or MBX-269. 3. For Acer Laptops Look for a model name like: Z5WAH or LA-B091P (Compal). 🛠️ Recommended Steps for Schematics
Once you have identified the actual OEM model number (like Quanta R33 or Inventec 6050A...), use these resources to find the schematic:

HSB J MV-6 94V-0 E89382 (also commonly identified as HannStar J MV-6
) is a specific multi-layered circuit board manufactured by HannStar, primarily used in laptops from brands like
. Finding a direct schematic PDF can be tricky because the identifiers on the board actually refer to the raw material and manufacturer rather than the specific laptop model's motherboard design. Understanding the Motherboard Identifiers HannStar / HSB
: The Original Design Manufacturer (ODM) that produces the physical circuit board (PCB). E89382 / 94V-0
: These are UL safety certification marks. "94V-0" indicates the board's fire resistance rating.
: Represents a specific revision or design of the board's base architecture. How to Find the Correct Schematic Because these markings are generic, you must find the internal motherboard code to locate a relevant schematic PDF or Boardview file. Check for Other Marks : Look for codes like (common for Sony) or (Compal), or specific HP part numbers. Verify Laptop Model : This board is frequently found in the Acer Aspire E5 series (E5-571, E5-531) and various Schematic Resources : Technical guides for related revisions like the HannStar J MV-4
are often used as references when the MV-6 version is unavailable. HP Support Community Technical Specifications Based on common implementations of this board: CPU Support : Intel Core i3, i5, i7 (often 4th generation Haswell). : Intel HM86 Express. : Typically 2x DDR3L SODIMM slots supporting up to 16GB. : SATA 3.0 interface and sometimes an mSATA slot. Common Repair Issues
If you are searching for this schematic to perform a repair, technicians frequently note these failure points: Power Input
: 19V rail issues often involving the DC power jack or charging circuit.
: Corruption is common; you may need to find a BIOS dump specific to your laptop's Product ID rather than just the "E89382" code. GPU/Thermal
: Discrete graphics versions (like those with NVIDIA GeForce 820M) often suffer from thermal-related solder failures. HP Support Community or to identify a specific component on the board? To find a better schematic for an HSB
Finding the exact schematic for an HSB J MV-6 94V-0 E89382 board can be tricky because these numbers are actually manufacturing codes rather than the specific motherboard model. Hannstar is the PCB manufacturer, and E89382 is a UL safety certification number shared across many different boards. How to Find the Correct Schematic
To find a precise schematic or "better" document, you need the motherboard code (often called the board ID or board code). This is usually silk-screened on the motherboard itself. Look for codes like: Compal codes (e.g., LA-XXXXP) Quanta codes (e.g., DAXXXXMBXXX) Wistron codes (e.g., 48.XXXXX.XXX) Potential Matches & Sources

Before hunting for a schematic, you must understand what you are looking at. This string is a combination of UL flame ratings, internal manufacturer codes, and a model revision.
HSB J: This is most likely the manufacturer’s internal model code or a customer-specific designator for a sub-assembly. "HSB" could refer to a specific OEM (Original Equipment Manufacturer) like Hon Hai/Foxconn, or a power supply design house. The "J" often denotes a revision level (e.g., version J, or a lead-free/RoHS compliant variant). HSB J: This is most likely the manufacturer’s
MV6: This is the product series or voltage/current rating code. In many switching power supplies or inverter boards, “MV6” indicates a specific topology (e.g., a multi-output flyback converter). It may also refer to the physical form factor (e.g., 6cm x 6cm mounting pattern).
94V0: This is a critical safety certification. It is not a model number. The “94V0” is a UL94 flammability rating. It means the PCB substrate material passes a vertical burn test, extinguishing within 10 seconds. This tells you the board is designed for commercial/industrial use where fire safety is paramount (TVs, monitors, chargers).
E89382: This is the UL File Number (E number). This is the most useful part for identification. The E89382 corresponds to the recognized component listing for the PCB manufacturer under Underwriters Laboratories. When searching for a schematic, ignore this number unless you are looking for regulatory filings. It identifies the factory, not the circuit.
The Takeaway: You are looking for a schematic for a HSB model MV6, revision J, built on a 94V0-rated board. The “E89382” is a red herring for circuit tracing.
Search query rating: 2/10. It’s too specific with noise (94v0, hsb j) and too vague with the device type (Is this a TV? A vacuum? A solar inverter?).
The fix: Search "E89382" "MV6". Forget the rest. If that fails, buy the board and trace it yourself.
Good luck, and happy debugging.
Do you have a photo of the board? If you can read the main chip number off the surface, drop it in the comments—I can help you find the pinout.
Together, these markings are typical on PCB substrates, insulation materials, connectors, or other components to show the material’s flame rating and the UL listing identifier plus vendor/manufacturer coding.
The schematic maps the primary power rails, typically converting input voltage (e.g., 12V or 5V) down to logic levels required by the processor and memory.
The schematic diagram details the electrical connectivity and logic design of the MV6 revision board. It is an essential resource for engineers performing the following tasks:
Go to UL’s Product iQ database. Search for E89382. This will reveal the legal manufacturer of the bare PCB.
