Replacement Power Button Board for Inspiron 17 7737

This new circuit board is the exact replacement for the power button assembly in the Dell Inspiron 17 7737 laptop. It restores the ability to turn the notebook on and off when the original board has failed or been damaged. The part carries Dell OEM designation D0H70 and alternate reference 50.48L03.001.

Upgrade from a non-functional or intermittent switch

If the laptop no longer responds to the power button, works only at certain angles or requires multiple presses, this board replaces the faulty component directly. The jump is worth it when the machine is otherwise sound and a full mainboard swap would be excessive cost for a single switch failure.

Fits inside the existing chassis cut-out

The board slots into the original mounting points and connects to the mainboard via the factory ribbon cable, so no case modification or extra wiring is required. It frees you from work-arounds such as wake-on-LAN or lid-open power-on and returns the notebook to normal front-panel operation.

Questions about this item

Does the D0H70 power button board fit the Dell Inspiron 17 7737 chassis?

Yes, the D0H70 is the OEM power button circuit board made for the Dell Inspiron 17 (7737) and mounts inside that chassis.

How is the D0H70 board installed in the Inspiron 17 7737, and what step is often missed?

Remove the bottom case and keyboard deck, disconnect the old board cable, fit the D0H70, reconnect the cable, then reassemble; the step often missed is re-seating the cable fully into the ZIF connector.

When should the 50.48L03.001 power button board be replaced in the Inspiron 17 7737?

Replace the 50.48L03.001 board if the laptop will not power on, the button feels stuck, or the board shows corrosion or cracked traces.
