Moderate

Steps

Time Required

20 - 30 minutes

Introduction

Use this guide to replace the power port (aka charging port, barrel jack, or power connector) in your HP EliteBook 840 G8 laptop.

If your power connector port has a loose connection, is obviously damaged, or your laptop isn't charging, it may be time to replace the charging port.

Before starting this repair, test your laptop with another cable to make sure the issue is with the port itself and not with your charging 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 power connector's sliding connector to walk it completely out of its socket near the left hinge.

    • During reassembly, make sure the side of the connector marked with a black dot is facing up before reconnecting the cable.

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.
