2. 手順9
  You can test the button on the motherboard itself to see if it's the motherboard and not the button, if so you may need to replace the motherboard.
  
  Use tweezers to remove the button.
  
  Once the button is taken out replace it with your new button. You may notice rubber-like holders on the sides, make sure they line up with the frame.
