(often listed as E89382) is a specialized printed circuit board (PCB) frequently used in industrial control systems and certain older laptop models from manufacturers like Dell, Acer, and HP. 1. Key Identification
The markings on the board refer to manufacturing standards rather than a single specific device model: HannStar: The PCB manufacturer. MV-4: A generic board design series.
94V-0: A standard UL (Underwriters Laboratories) flammability rating for the plastics and materials used in the board. E89382: The UL certification number for HannStar. 2. Common Hardware Variants
Because "K MV-4" is a base board type, specifications vary by the device it was built for:
Industrial Control Version: Discontinued control boards (often labeled K-MV-4-94V-0) typically feature a built-in CPU, multiple female connectors, and I/O ports for machine control.
Laptop Version: Found in older consumer laptops like the Dell Studio 1435/1535 (Quanta FM6) or Acer Aspire One series. These typically use: CPU: Socketed or BGA (e.g., Intel Merom or Penryn). Graphics: Integrated or discrete (e.g., ATI M82S). Memory: DDR2 SO-DIMM slots. Ports: USB 2.0, VGA, HDMI, and RJ-45 Ethernet. 3. Technical Documentation & Troubleshooting
Official manuals are rarely available directly from HannStar, as they are an OEM manufacturer. Instead, search for the service manual of the specific laptop or machine model name found on the external casing. HannStar Computer Motherboards for sale - eBay

To prepare an accurate write-up for a HannStar K MV-4 94V-0 motherboard, it is first critical to clarify what these markings actually mean. Many users mistake these codes for the specific motherboard model, but they are actually industrial manufacturing and safety standards.
Here is a proper technical breakdown and guide to identifying your exact board. 1. Decoding the Markings
This is the manufacturer of the raw printed circuit board (PCB) fiberglass/textile, not the manufacturer of the computer or the designer of the circuitry. HannStar manufactures boards for major brands like ASUS, Dell, HP, and Lenovo.
This denotes the specific internal layout batch or revision of the raw PCB laminate supplied by HannStar. This is an Underwriters Laboratories (UL) flame rating
. It indicates that the plastic/laminate materials used on the board are self-extinguishing and meet specific safety standards against burning.
Because HannStar supplies raw boards to dozens of different computer manufacturers, there are hundreds of completely different motherboards (with different sizes, CPU sockets, and ports) that all feature the exact same "HannStar K MV-4 94V-0" print. 2. How to Find the True Motherboard Model
To write a proper technical description, sell the board, or find the correct schematics and BIOS, you must locate the Platform Vendor Model
. Look across the board for printed or stickered codes that correspond to the actual engineering platform. Common manufacturer formats to look for include: Look for codes starting with "DA0" (e.g., DA0TW7MB8G0 DA0ZR1MB6D0 Look for codes ending in "P" (e.g.,
Look for a 4 to 5-digit number followed by a revision (e.g., 48.4GH01.011 Look for short codes typically near the RAM slots (e.g., K51IO Main Board Rev 2.1 3. Template for a Proper Write-Up
Once you find the true model number using the step above, you can fill out this professional layout for listings, repair logs, or inventory:
Important Note: This is not a standard consumer motherboard (like an ASUS, Gigabyte, or MSI product for an Intel/AMD CPU). It is a specialized controller board, typically used for LCD panel repair, retrofitting, or industrial displays.
The numbers "94V-0" refer to a UL flammability rating (meaning the PCB material is fire-resistant), not a model number.
