Water damage

What you need

1. Step 1 Lower Case
  Use a Phillips #0 screwdriver to remove the eleven 6.9 mm screws that secure the lower case.
  
  Make sure all the screws on this side get taken out because there could be a label or warranty sticker covering up a screw that might be missed.
  
  Insert an opening pick into the gap between the lower case and chassis.
  
  Slide the pick around the entire perimeter of the laptop until the lower case fully releases.
  
  Remove the lower case.

  The two screw holes (marked in orange) on the bottom won't have screws associated with them since they were removed earlier when the base was removed.
  
  Unseat the speaker cable from the black plastic hooks on the lower side of the battery.
  
  Lift the battery up and out of the chassis.
