Introduction

Use this guide to replace the USB board in your HP EliteBook 840 G8 laptop.

The USB board includes the two USB‑A ports and audio jack. If the USB‑A ports or headphone jack on your HP EliteBook 840 G8 are broken or have a loose connection, you may need to replace the USB board.

Before replacing the connector board, test the ports with a different cable to make sure the problem is with the port itself and not the cable.

    • Before starting your repair, allow your laptop's battery to drain below 25%—a charged lithium-ion battery is a potential safety hazard if accidentally damaged.

    • Save your work, fully shut down your laptop, and unplug all cables.

    • Despite the standards, Phillips screwdrivers can vary in size and shape—two drivers labeled as the same size may fit differently in the same screw. Use the size that fits the most snug into the screw head to avoid stripping it.

    • Use a Phillips screwdriver to fully loosen (but not remove) the five captive screws securing the bottom cover.

    • Position your laptop so the rear edge (with the screen hinge) is closest to you.

    • Insert the flat end of a spudger between the rear edge of the bottom cover and the frame, near the middle screw and ELITEBOOK text.

    • If you're having trouble inserting your spudger, make sure the screw is fully loosened. If necessary, use your fingers to gently pull the screw up.

    • Use your spudger to pry up the cover to release the clip securing it.

    • Leave the spudger inserted under the bottom cover for the next step.

    • Slide your spudger along the rear edge toward one of the corners to release the rear edge clips.

    • Rotate your spudger around the corner and up the edge to release the clips securing the short edge of the cover.

    • Lift and remove the bottom cover.

    • The cover should lift away easily. If you feel resistance, use the flat end of a spudger to release any remaining clips, and check that all screws are fully loosened.

    • During reassembly, slide the clips along the front edge of the cover (opposite the hinge) into their slots on the frame, then lay the cover down. Press firmly around the perimeter to engage all of the clips.

    • Position your laptop so the front edge (opposite the screen hinges) is closest to you.

    • Use the point of a spudger or your fingernail to push on alternating sides of the battery's sliding connector to walk it completely out of its socket.

    • Use the flat end of a spudger to push the USB board sliding connector fully out of its socket.

    • Always push or pull the connector, not the cables themselves.

    • Use a clean fingernail or the flat end of a spudger to flip up the hinged locking flap on the USB board ZIF connector.

    • Depending on your laptop configuration, there may be a metal bracket on the board you need to remove.

    • Lift the left edge of the USB board and pull it toward the fan to remove the board.

    • During reassembly:

    • Hold the cable out of the way so it doesn't get stuck underneath the board.

    • Slide the ports towards their cutouts in the chassis at a shallow angle, allowing the alignment posts to slot into place.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler. Depending on your region, used HP devices and parts can be returned for reuse or recycling through the HP Planet Partners program.
