What you need

Tools

1. Step 1 Before you begin
  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.

1. Step 2 Unfasten the bottom cover
  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.

2. Step 3 Release the bottom cover clips
  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.

4. Step 4
  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.

6. Step 6 Remove the bottom 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.

1. Step 7 Disconnect the battery
  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.

1. Step 8 Remove the memory module
  Depending on your laptop configuration, you may need to remove a metal shield or plastic cover to access the memory modules.
  
  Your laptop has two memory slots, each with a pair of metal arms that secure a memory module. This laptop supports DDR4 SODIMM modules.
  
  Simultaneously push out the metal arms on each side of the memory module until they disengage and the module pops up at a slight angle.
  
  Pull the module out of its socket to remove it.
  
  Use the same process to remove the other memory module.
  
  To install a memory module, insert it into its socket at a slight downward angle, then push down firmly until both metal arms lock it in place.
  
  If only installing one module, insert it into the slot labeled DIMM 1.
