Replacement IO Board for HP ProBook 440 450 455 470

This SMUGDESK dual USB port subboard carries part number LSB183P 455MME32L and is built as a direct replacement for the original component in HP ProBook 440, 450 G2, 455 and 470 series notebooks. It arrives with the connecting cable already attached and is fully pretested to deliver stable USB data transmission and reliable port operation. The board follows the original circuit layout so it plugs straight into the motherboard without any soldering. It is intended for repair shops and DIY technicians fixing damaged or worn-out USB interfaces.

Verify Model and Part Number Before Ordering

Confirm that your laptop belongs to the ProBook 440, 450 G2, 455 or 470 series and that the original board carries the exact part number LSB183P 455MME32L. The supplier notes that compatibility issues arise when the model or part number does not match, so cross-referencing both details is essential before purchase. No soldering equipment is required for installation, but access to the internal subboard connector is necessary. The preattached cable must align with the motherboard header on your specific unit.

Stable Connection Under Continuous Use

Each board is tested before shipping to ensure normal USB data transmission and stable connection performance during extended operation. The OEM-spec design mirrors the original circuit and connector definition, so signal integrity is maintained across sustained data transfers rather than only in brief bursts. This makes the part suitable for daily workloads that keep the USB ports active for long periods. The direct plug-and-swap fit preserves the factory electrical characteristics without modification.
