Genuine Dell Vostro 3580 3590 I/O Daughterboard

This genuine Dell OEM daughterboard carries part number 74P3P and board code EDI54. It is engineered specifically for the Dell Vostro 3580 and 3590 laptop chassis. The blue LS-G712P board restores the side I/O panel when the original ports fail. It provides the exact fit and electrical match required for factory-level reliability.

Sustained connectivity through dual USB 2.0

The board carries two USB 2.0 ports for continuous peripheral use such as mice, keyboards and flash drives. A standard VGA port maintains a steady video signal to external monitors or projectors during long sessions. Because the daughterboard connects to the motherboard via a ribbon cable, data and video paths remain stable without the intermittent contact that worn sockets create.

OEM screw mounts and ribbon interface for precise

The part uses the original screw mount points so it seats securely in the existing chassis standoffs. Its ribbon cable connector aligns with the motherboard header without adapters or cable routing changes. The blue PCB matches the factory colour coding used in Vostro 3580 and 3590 service manuals. Technicians can swap the board using only standard screwdrivers and the existing mounting hardware.

Questions about this item

Does the USB 2.0 section of the LS-G712P board generate noticeable heat during all-day use?

The board is a passive I/O daughterboard with no active components, so it does not produce measurable heat during continuous operation.

Must the laptop chassis already have the ribbon-cable header and screw mounts for the EDI54 board?

Yes, the replacement board connects via its ribbon-cable connector and OEM screw-mount points that exist only on the Vostro 3580 or 3590 chassis.

Will the VGA port on this 74P3P board drive a legacy monitor that only accepts analog input?

The VGA port provides a standard analog video signal, so it works directly with older monitors and projectors that require a VGA connection.
