Center Control Cover for Vostro A840

This genuine Dell part replaces the center control power button cover assembly on the Vostro A840 laptop. It restores the original look and tactile response of the power button area. The component carries part number J995H and is supplied new.

Simple snap-in installation for experienced users

The cover snaps into the chassis once the keyboard deck is removed, so disassembly of the upper case is required. First-time builders often struggle with the fragile ribbon cables and hidden screws beneath the palm rest. Professional fitting is recommended if you have not opened a Dell Vostro chassis before.
