Genuine Dell Power Button Cable PNMWD

This genuine Dell power button board cable carries part number PNMWD and fits the Vostro 3450 and Inspiron 14R N4110 laptops. It restores the front-panel power switch function when the original ribbon or button fails. The part is a working pull from a tested system and is guaranteed to operate correctly.

Verify exact model and connector before ordering

Confirm that your laptop is a Vostro 3450 or an Inspiron 14R N4110, as other similar-looking models use different ribbon layouts. Check the existing cable part number against PNMWD to ensure the connector pitch and length match the motherboard header. Opening the chassis requires removing the keyboard bezel, so have suitable pry tools ready.

Replaces a faulty or damaged power button ribbon

This cable replaces a broken power button assembly that prevents the laptop from turning on or causes intermittent startup. The upgrade is worth it when the original ribbon is torn, the button actuator is stuck, or liquid damage has corroded the contacts. It is not for buyers who need a complete palm-rest assembly or a different keyboard layout.

Questions about this item

Does the package include only the power button board cable or are additional mounting brackets or screws supplied?

The listing covers the power button board cable with part number PNMWD; mounting brackets and screws are not included and must be sourced separately.

My laptop is a Vostro 3450 — will the PNMWD cable fit, or is there a different version for the Inspiron 14R N4110?

The same PNMWD cable is compatible with both the Vostro 3450 and the Inspiron 14R N4110, so no separate version is required.

Once the PNMWD cable is installed, will the power button respond immediately without any BIOS update or driver installation?

The cable is a direct hardware replacement; it restores the physical button connection and requires no BIOS update or driver installation to function.
