: Used in models like the IdeaPad Y510 and Lenovo B575e . Acer : Commonly found in the Aspire E5 series.
: Sites like DIY-LaptopRepair offer dedicated threads for specific revisions and power sequences.
This deep-dive article clarifies the manufacturing data behind these markings, lists the device manufacturers that utilize these PCBs, and guides you on how to track down the correct schematics or boardviews. Decoding the Board Markings e89382 hannstar j mv-4 94v-0 schematics
Allows voltage injection to locate short circuits by monitoring current draw.
Because HannStar makes millions of boards for hundreds of different computer models, Why Searching for "E89382" Won't Find Your Schematic
: This is a UL (Underwriters Laboratories) certification number. It essentially confirms that the board meets specific safety and manufacturing standards for fire resistance.
Compal codes : Look for something like LA-XXXXP (Example: LA-9104P ). Provides a high-level view of how major components
To help narrow down your search right now, please let me know you are repairing, or any other alphanumeric codes printed on the board. I can then try to locate the specific motherboard manufacturer model or provide targeted troubleshooting steps for that device. Share public link
: This is the name of the company that manufactured the bare printed circuit board (PCB). They make parts for many big brands like ASUS, Acer, HP, and Dell.
Turn the board over and look for screen-printed text in white, yellow, or black ink. Look for identifiers such as: : K53SV MAIN BOARD REV: 2.0 or X550CC Compal Style : LA-9911P or LA-A621P Quanta Style : DA0R53MB6E0 Wistron Style : 48.4GV01.011 2. Check Under Stickers and RAM Slots
If you are a component-level repair technician troubleshooting a dead laptop, searching for schematics using only these terms will often lead to a dead end. HannStar is a major Taiwanese Printed Circuit Board (PCB) fabricator. They manufacture the bare fiberglass boards for hardware designers like ASUS, Compal, Quanta, MSI, and Wistron, who then build the actual circuitry. Share public link : Used in models like
To locate the actual schematic or boardview file, you must find the true motherboard part number. This number is usually silkscreened in white ink or printed on a small barcode sticker on the board.
Locate the charging port on the schematic. Trace the voltage path to the first two isolation MOSFETs (often referred to as PQ1, PQ2, etc.).
Before diving into the schematics, it is helpful to understand what these codes mean:
