Replacement IO Board for Latitude E7440

This Dell H65F0 circuit board restores the USB and audio ports on a Latitude E7440 notebook. It is a direct OEM replacement for a damaged or missing original databoard. The part fits only the listed model and connects directly to the system motherboard. Technicians and owners repairing port failures will use this component.

Port Capacity and Limits

The board provides one USB port and one audio jack for daily peripheral connection. It handles standard headsets, flash drives, and similar low-power devices without issue. The single USB lane means bandwidth is shared if a hub is added downstream. High-power or multi-device workloads will exceed the available ports and current budget.

Build and Connector Implications

The assembly mounts inside the chassis and mates with a dedicated motherboard header using the H65F0 part number. Alternate references VAUA0 and LS-9591P identify the same spare across service manuals. No cables or brackets are included with the bare circuit board. Proper seating of the connector is required for reliable port detection.
