    • 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.

    • 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.
