This specific PCB material is used across a variety of laptops, including the HP ProBook 4510s (Inventec Zenith), Lenovo IdeaPad Y510 , Toshiba Satellite C850 , and Dell Latitude N4030 . Available Documentation & Resources
It is a common misconception that "HannStar J MV-4" is a specific laptop model. In reality, these identifiers describe the physical board: : The PCB manufacturer. MV-4 : The specific type of circuit board material.
Launch OpenBoardView and load your HannStar_MV-4.brd file. The board likely has a short on the +3VALW (Always On 3.3V) or B+ rail.
The most common fault on these boards usually involves the power management ICs (PMICs) or "no power" states caused by shorted capacitors on the 3.3V or 5V rails. When a technician probes the board with a multimeter and finds a short to ground, they have to find the culprit among hundreds of capacitors.
E89382 is the most definitive identifier here—it is HannStar Board Corp’s official , a certification assigned by Underwriters Laboratories. Anyone can look up this number in the UL Product iQ database to confirm the board’s safety credentials. hannstar j mv4 94v0 e89382 boardview exclusive
ASUS motherboard identifiers are typically very clear. Look for a bold white print such as: X550CC REV 2.0 UX31A MAIN BOARD REV 3.1 K53SD 2. Acer / Compal / Wistron Boards
Before searching for files, it is critical to distinguish the manufacturer of the board material from the actual design of the laptop: The manufacturer of the raw PCB laminate.
Selecting a power rail (like +3VLP or +19V ) highlights every single component connected to that circuit across the entire board. Step-by-Step Diagnostic Guide Using the Boardview

: Easily find microscopic components like "R2301" or "C5102" without using a magnifying glass to scan the physical board.
The “HannStar” here that makes monitors and LCD panels. In the context of a motherboard, HannStar Board Corp is a major Taiwanese manufacturer of printed circuit boards (PCBs) and components for OEMs like Dell, Lenovo, and Toshiba. This company is UL-certified (see below) to produce PCBs that meet international safety standards.
For most technicians, is the best solution. Created by Chloridite in 2016 to democratize access to repair tools, it is free, open-source, and cross-platform (Windows, Mac, Linux).
An excellent, free, community-driven database for bios dumps, schematics, and boardviews. MV-4 : The specific type of circuit board material
Socket P (478 pins) for Intel Core 2 Duo or integrated options like the Intel Core i3-2367M.
While the exact specifications vary by the laptop model the board is installed in, we can infer general features from repair logs and OEM documentation:
To understand the value of the file, we first have to decode the identity of the board.
This technical guide breaks down what these motherboard markings actually mean, how to locate the correct boardview files, and how to use them effectively to revive dead hardware. Decoding the Motherboard Markings
