Genuine Dell Latitude E5520 Power Button Board

This genuine Dell OEM circuit board integrates the power button and microphone port for the Latitude E5520 laptop. It arrives as a tested working pull and includes the necessary ribbon cables for installation. The part is intended for technicians or owners repairing a faulty power switch or audio input on this specific model.

Ribbon Cables Included for Direct Replacement

The bundled ribbon cables eliminate the need to source separate flex connectors when swapping the original board. This reduces part-mismatch risk and shortens the repair because the cables are already matched to the board’s pinout and length. No additional software, drivers or mounting hardware are supplied with this component.

Limited to Latitude E5520 Chassis

The board’s connector layout and mounting points are engineered only for the Latitude E5520, so it will not fit other Dell latitudes or third-party laptops. Buyers needing a power-button assembly for a different screen size, port arrangement or newer chassis generation must source the correct model-specific part instead.

Questions about this item

Does the power button board include the ribbon cable for future replacement?

Yes, the circuit board ships with the ribbon cable attached, so a later swap does not require sourcing the cable separately.

What fails first on this part if the laptop runs continuously?

The mechanical power button switch is the component most likely to wear out under constant daily actuation.

Does the board add noticeable heat or fan noise during all-day operation?

The board is a passive switch and audio jack assembly; it generates no measurable heat and produces no fan noise.
