Solved: Issue with motherboard - HP Support Community - 6415432
Доброго времени суток, имеется sony vaio платформа - hannstar j mv 6 94v-0 e89382, ситуация такова, стоял чипак 216-0833002, т. к. Ассоциация сервисных центров E89382 for HANNSTAR BOARD CORP | UL Solutions
: Look for a "Spare Part" number (e.g., 123456-001) or a code like DA0LX6MB6H1 . e89382 mv-6 94v-0 schematics
- Once you have your transformer, you'd design a schematic that includes the transformer, a rectifier circuit (e.g., bridge rectifier), a capacitor for filtering, and a voltage regulator (if necessary).
If you successfully locate a schematic labeled "Power Supply MV-6 Rev 3.0" or something similar, here is how to navigate it against your physical e89382 board: Solved: Issue with motherboard - HP Support Community
| Laptop Brand | Reported Models / Motherboard ID | Additional Information / Source | | :--- | :--- | :--- | | | Compaq CQ58 (SPS:694693-501), HP 4440S (11243-1), HP Envy 17, HP ProBook 4540S | A very common pairing; often searched with board number starting with 6050A... . | | Toshiba | Toshiba Satellite L650D, C850-G2K | Frequently uses the very similar MV-4 version. | | Lenovo | IdeaPad 5 15ITL05 (board: HSB J MV-4 ) | This specific Lenovo model uses the older MV-4 revision. | | ASUS | K42J / X42J series, Z92J (A6JC/M) | ASUS often obscures its board number, making the E89382 marking a vital clue. | | Ubiquiti | NanoBeam M2 (NBE-M2) | Confirmed in network equipment, not just laptops, showing the PCB's wider use. |
The mark is a standard plastics and material flammability rating. It guarantees that the board's substrate is self-extinguishing and will not fuel a fire if a component suffers a catastrophic short circuit. 2. Where Are These Boards Used? - Once you have your transformer, you'd design
Attempting to reverse-engineer or repair a 94V-0 rated board involves (rectified 230V AC = 325V DC; rectified 110V AC = 155V DC). Bulb capacitors can hold a lethal charge for hours.
: This indicates the flammability rating and material specification of the board, often used by HannStar to denote a multi-layer board meeting specific safety standards.
The "MV-6" PCB has been identified across several laptop models. The table below consolidates the most commonly reported associations from repair logs and forum discussions:
