Replacement power button and cable for Dell Studio 1440 laptops
This replacement cable connects the power button board to the motherboard on Dell Studio 1440 laptops. It is a new, genuine Dell OEM component tested to ensure reliable operation. Installing this part restores the ability to turn the system on and off correctly.
This cable fits only the Dell Studio 1440 model listed in the compatibility data. Buyers needing parts for other Dell series or different laptop brands should look elsewhere. Technicians requiring a complete palm-rest assembly or motherboard will need separate components not included here.

The cable is a passive ribbon assembly with no moving electronics; it only needs replacement if the flex fractures or the connector pins bend during service.
Repeated hinge movement stresses the ribbon at the fold point, so conductor fatigue at that bend usually appears before the switch mechanism itself wears out.
