The Dell Latitude E5430v Bluetooth Module is installed/replaced in the following steps.
Remove the two screws from the main back panel and slide the panel to remove it. Then remove the screws from the postions marked below. Lift and jiggle at the arrows and remove the cover. Slide out the DVD drive.
Remove the additional screws now visible (below).
Lift the edge of the keyboard surround carefully and get a small screwdriver under just enough to raise the front edge, taking care not to bear on visible edges or surfaces.
Within reason you can lift safely here as the only thing that can be damaged is the ribbon connector which is just over half way up under the cover.
After it starts to come away, it can release quite easily with a wiggle on the way up.
Remove the four remaining screws screws holding the keyboard in.
Remove the final five screws and unlock the three ribbon connectors and free the ribbons.
Assemble the bluetooth module and cable. You'll feel the slightest click as it goes into place (most times:).
A very slight clicking into place can usually be felt when pressing the bluetooth module cable into the motherboard too. Screw the scre down until the module doesnt move, not just until you feel some resistance from the locktite on the new screw.
