Dell Inspiron 14 Power Button Cable
This new OEM cable carries the power-button signal for Dell Inspiron 14 models 3451, 3452 and 3458. It restores the ability to turn the laptop on and off when the original ribbon has failed or been damaged during service. The part is a direct replacement for the factory-installed assembly.
Part Number D9KF1 Compatibility
The cable is identified by Dell part number D9KF1 and the on-board markings IRIS14 PWR and 450.03V02.1001. Matching these codes to the laptop’s service tag or the existing cable is the only way to confirm fitment before purchase.
Installation and Function
The ribbon plugs into the motherboard header and routes through the top case to the power button module, requiring partial disassembly of the palm-rest area. Once seated, it re-enables normal power cycling without additional configuration or drivers.
