This is a standard for plastics and electronics flammability. A 94V-0 rating certifies that the device will self-extinguish within a specific timeframe if it catches fire, allowing it to comply with global electronic safety regulations. : A global underwriting standard certifying that the

: This indicates the manufacturing revision or layout style of the raw PCB layer stack. For example, HannStar also produces MV-4 variations of similar layouts.
The text strings printed on a circuit board do not represent a specific motherboard model or a BIOS version, but are instead regulatory, manufacturing, and safety markings from the PCB manufacturer HannStar . Because these text markings are shared across completely different laptop and All-in-One (AIO) motherboards by brands like HP, Sony, and Medion, locating the correct BIOS update requires finding the actual PC product ID rather than using these PCB codes.
