HP Elitebook 830 G7 or G8 Top Cover replacement

Introduction

Perhaps the keyboard has been damaged or the layout is wrong?

In that case you need to replace the top cover.

Flip the notebook.
Unscrew the screws.
Open the base enclosure using a plastic wedge (a credit card might also work). Follow the direction of the green arrows.

Detach the battery using a plastic spudger.
Unscrew the battery screws. Be aware not to damage the speaker cables.
Now remove the CMOS battery. Beware: it is glued to the enclosure. So remove with care.
Remove the SIM slot.
Now detach all connections with the mother board (using a plastic spudger). Unscrew the black (mostly flat) screws until the mother board is loose.
Put the Display Cables to the top side. In that way the cables aren't damaged when removing the top cover.
Remove the loose plastic parts on the motherboard.

Detach the mother board.
Unscrew all the remaining components from the top cover.
Unscrew the black screws in the top corners until you can separate the top cover and the display.

Attach the new Top Cover.
Follow the previous steps in reverse order.
Beware when closing the Base Enclosure: slide it towards the front at a 30 degree angle until it snaps in place. Screw everything back together. In this way you prevent an open gap at the front side.
