Replacement Power Button Board for Dell Inspiron

The Dell 94MFG power button board restores the power-on function on compatible Inspiron 15 and Vostro 15 laptops. It fits models 5558, 5559, 5555, 5566 and Vostro 3558. The part includes the button assembly and its connecting cable. Installation returns the original switching feel without modification.

Direct OEM Substitute for Worn or Damaged Switches

This board replaces a faulty or intermittent power button on the listed Dell chassis. The swap is worthwhile when the original switch fails to register presses or requires excessive force. It matches the factory connector and mounting points, so no adapter or soldering is needed. The repair suits technicians and owners comfortable opening the palm-rest assembly.

Single-Function Switch Module with No Expandability

The component handles only the power-on signal and its indicator LED. It adds no extra ports, sensors or lighting controls beyond the stock design. Headroom is limited to the original electrical spec; the board cannot support additional buttons or remapped functions. Buyers needing volume keys, fingerprint readers or backlight controls must source the separate modules designed for those roles.

Questions about this item

Does the 94MFG power button board align with the chassis screw points on an Inspiron 15 5558?

Yes, the 94MFG board is built to the original Dell layout for Inspiron 15 5558, 5559, 5555 and Vostro 15 3558 so the mounting holes match the factory chassis.

Which connector orientation avoids pin damage when fitting the 94MFG board?

The flexible cable plugs into the motherboard header with the gold contacts facing down; forcing it reversed bends the pins and prevents the laptop from powering on.

How often should the 94MFG power button board be replaced under normal use?

The board is a solid-state switch with no moving contacts, so it typically lasts the life of the laptop; only physical damage or liquid exposure would require a swap.
