The e prefix followed by a number is a for a recognized component. Specifically, e89382 refers to a specific manufacturer’s PCB substrate material that has passed UL’s rigorous testing. This number is traceable in UL’s online database (UL Product iQ). Manufacturers using this mark have certified that the bare board material meets specific electrical, mechanical, and flammability standards.
. While these markings are often found on laptop motherboards (particularly for Acer, HP, and Dell), they are not unique to a single device model. Key Identification Breakdown
This is a flammability rating . It indicates that the plastic/fiberglass material will self-extinguish within 10 seconds during a fire test. Almost every modern electronic board carries this rating.
At first glance, this looks like a random password. However, to a trained eye, this string is a roadmap. It tells you who made the board (or at least the raw laminate), what safety standards it adheres to, and a revision number. But the holy grail—the —remains elusive.
This usually designates the model series or the revision of the PCB layout. In the context of monitor power boards, "MV" often alludes to the "Media Vision" or specific inverter architecture used to power the backlight (CCFL) tubes of older LCD screens.
