It is crucial to understand that is not the model of your motherboard.
Electronics repair professionals, engineers, and DIY hobbyists often encounter specific alphanumeric codes stamped onto printed circuit boards (PCBs). One such common marking is .
It helps you visualize trace paths buried deep within multi-layer PCBs (often 4 to 8 layers deep). Common Boardview File Extensions
At its heart, the code is the ID stenciled onto the PCB of a laptop motherboard. This identifier has been spotted on a wide range of laptops from major brands like Toshiba, MSI, Acer, and ASUS , indicating that HannStar was a major original design manufacturer (ODM) producing logic boards for the wider industry. Here is a breakdown of what each part of the identifier means: E89382 Hannstar J Mv-4 94v-0 Boardview --39-LINK--39-
SATA 3.0 interfaces (6Gb/s) for SSDs/HDDs and occasionally mSATA slots. 📥 Finding the Correct Boardview
A technician on ChinaFix described a case where the board was dead with a full short circuit. Using the boardview, they located PU3801 (a 4407A MOSFET) as shorted, replaced it, and then traced additional shorted capacitors PC4518 and EC97 that were causing the protection to trigger.
If the laptop triggers the charger's protection, there is likely a shorted capacitor. It is crucial to understand that is not
Compal is a major contract manufacturer. Their board numbers always follow a specific pattern consisting of "LA-" followed by four digits and a revision number. Examples: LA-9104P, LA-D801P, REV: 1.0 3. Quanta Boards (Common in HP, Acer, Toshiba)
The code is a UL (Underwriters Laboratories) file number identifying HannStar Board Corp. The J Mv-4 94v-0 part refers to the material standard—specifically, a rigid, flame-retardant epoxy-woven glass fabric circuit board.

When you open a boardview file using a viewer program, you can:
Click on any pin of an Integrated Circuit (IC), and the software highlights every other trace, resistor, capacitor, and via connected to that network (Net).
Look for silkscreened text or stickers matching these formats: Look for codes like X550CC REV 2.0 , K53SD , or UX31A .
