Introduction

Use this guide to replace the left speaker in your HP EliteBook 840 G9 laptop.

The left speaker is on the same side of the laptop as the HDMI and USB‑C ports.

It's recommended to replace both speakers at once, even if only one is faulty. Click here for the right speaker replacement guide.

You may need to replace the speakers if they have distorted sound, crackling noises, or no sound at all.

    • 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 (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.

    • Slide the cover towards the screen hinge to disengage the clips on the opposite edge.

    • Lift and remove the cover.

    • The cover should come away easily. If you feel resistance, use the flat end of a spudger to release any remaining clips.

    • 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. Firmly press around the perimeter of the cover to engage all the clips.

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

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

    • Grommets secure the top and bottom of the speaker.

    • Lift the speaker straight up and off its posts to remove it.

    • During reassembly:

    • Make sure the new speaker has grommets. If it doesn't, transfer over the original grommets.

    • Align the grommets over their screw posts and press down gently to secure the speaker in place.

    • Don't press down on the rectangular rubber diaphragm on the top edge, or you'll damage the speaker.

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.
