Replacement IO Board for Inspiron 5551 5552

This Dell IO circuit board carries two USB ports and an audio jack for Inspiron 5452, 5551 and 5552 laptops. It restores the side-panel connectivity that fails when the original databoard is damaged. The part number is 2YRVT with alternates AAL11 and LS-B914P.

USB and audio limits on this board

The board provides only the two USB ports and one audio connector shown in the specification. No additional interfaces such as video outputs, card readers or extra USB lanes are present. Bandwidth and power delivery follow the laptop's mainboard design, which is not detailed in the supplied data.

Straightforward swap with cable care

Installation requires opening the chassis and disconnecting the fragile ribbon cable that links the IO board to the motherboard. The most common issue is tearing that cable or misaligning the connector during reassembly. Take time to route the cable exactly as the factory did.
