Exact-fit replacement IO board

This SMUGDESK LSB183P subboard restores dual USB ports and an audio jack on HP ProBook 440, 450 G2, 455 and 470 series notebooks. It arrives new with the matching 455MME32L flex ribbon cable for a direct motherboard connection. The part suits repair technicians and owners fixing physically damaged or non-working side ports.

Part number 455MME32L confirms compatibility

Only laptops that list this exact part number will accept the board and cable assembly. Verifying the number on the original faulty module is the single step that decides whether the repair will succeed. No other identifier in the listing guarantees a correct fit.

Stable signalling under daily use

The factory-spec layout maintains reliable USB data transfer and analogue audio output during extended sessions with flash drives, headsets or external storage. Hot-plug operation works without extra drivers, and the matched flex cable preserves the original internal routing inside the chassis.
