Power and Volume Buttons Board for Latitude E5420
This genuine Dell circuit board provides the power and volume button functions for the Latitude E5420 laptop. It is a new, OEM replacement part identified by part number 7V482. The component is designed to restore the original switching hardware when the existing board has failed.
Direct replacement restores front-panel control
The board integrates both the power switch and the volume up or down contacts used daily on the Latitude E5420. It handles normal button presses exactly as the factory unit did. Damage from liquid ingress or heavy physical impact would exceed what this spare part can remedy.

The assembly mounts inside the existing palm-rest cut-outs and connects via the original ribbon cable to the mainboard. No extra brackets, screws or cables are included beyond the circuit board itself. Installation requires partial disassembly of the laptop, so it suits technicians or experienced owners.
