2. Step 2
  Loosen all eight 4.5 mm captive Phillips #1 screws securing the lower case.
  
  Do not attempt to fully remove the screws. They are intentionally held in to the back of the board with stoppers. This will not prevent you from opening the case.

4. Step 3
  Insert an opening pick into the seam between the lower case and chassis.
  
  Run the opening pick along the entire perimeter of the device, prying every couple of centimeters, until the lower case fully releases.
  
  Lift the lower case up and off.

5. Step 4
  Use a T8 Torx screwdriver to remove the five 4 mm screws that secure the battery.
  
  These screws are very small. Take care not to lose them.

6. Step 5
  Pull the white battery connector directly out of its motherboard port.
  
  Grab the connector by the two tabs, and not by the wires.
  
  It does take quite a bit of force to disconnect the cable. Try wiggling it back and forth while you pull it out. Still, exercise caution to not damage your device.
  
  You can also use opening picks to disconnect the battery if you have short fingernails.
  
  Lift the battery up and out of the chassis.
