E89382 HannStar J MV-4 94V-0 isn't actually a specific motherboard model, but a set of manufacturing markings found on a wide variety of laptop motherboards and industrial equipment. If you are hunting for schematics, knowing how to decipher these codes is the first step to successful board repair. The Great Schematic Hunt: Deciphering the Codes
This is the critical identifier. "MV-4" is the internal code name for the PCB layout. This specific code is most commonly associated with laptop motherboards, specifically those found in older HP Pavilion and Compaq Presario series notebooks (often utilizing AMD chipsets).

The e89382 board is not a motherboard or a graphics card. It is a . Its job is to sit between the main logic board (GPU) and the actual LCD driver ICs bonded to the glass panel.
HannStar Board Corporation is a well-known OEM (Original Equipment Manufacturer). They produce motherboards for a wide variety of brands, including HP, Dell, Lenovo, and various television manufacturers. Because they are an OEM, their boards are often re-branded. A board that says "HannStar" on the silkscreen might actually be the internal backbone of an HP Pavilion or a specific Acer desktop. E89382 HannStar J MV-4 94V-0 isn't actually a
Repairing these boards often requires specific diagrams for the power rails (VCore, 3.3V, 5V) and system block layouts. Here are the most common matches for these markings: Lenovo Laptops : Often associated with the Lenovo Y510 Series Dell Laptops : Frequently found in the Dell Studio 1435/1535 or Latitude N4030. Generic ODM Boards : Platforms like the often carry these markings and have extensive 38-page schematic sets available for power and signal troubleshooting.

If you need only the power section, look up the datasheet for the main PMIC on your board (e.g., TPS65195 , RT6932 , or NOVATEK NT71368 ). The manufacturer’s reference design for that IC is often 80% identical to the HannStar implementation. "MV-4" is the internal code name for the PCB layout
: This is the UL (Underwriters Laboratories) file number for HannStar Display Corp, indicating the manufacturer of the raw PCB laminate.
The code "E89382" is not a part number. This is a UL (Underwriters Laboratories) file number. In the United States, electronic components must meet specific safety standards. The UL mark followed by the number E89382 indicates that the PCB material and design have been registered with Underwriters Laboratories. This number appears on millions of different HannStar boards.
