Steps:

  1. Make sure you have a clean desk space with plenty of room to separate the components.
  2. Ensure any devices or peripherals plugged into the laptop are removed and set aside.
  3. Using the system dialog, power off the computer to prevent data loss.
  4. Loosen and remove all ten (10) M2.5x5 screws.
  5. Carefully remove the bottom plate of the laptop by prying it from the hinges and working around the edges.
  6. Take caution when removing the laptop hinges, as they are fragile and can break.
  7. Disconnect the battery cable from the motherboard.
  8. Be careful not to bend the pins in the female connector! Make sure to apply equal pressure on both sides of the white male connector.
  9. Remove the four (4) M2x3 screws - there is one at each corner of the battery.
  10. Lift away the battery and place it on a flat surface.
  11. For temporary storage, place the battery on paper and tape the battery connector.

  31. Lift the metal brackets.
  32. I usually do this by opening the laptop. Be careful while doing this to avoid lifting and bending the plastics under or back.
  33. Then disconnect the DC-cable.
  34. You can remove the DC-connector by removing this screw. There are no markings, but I'd say this one is M2x2.

  35. Disconnect the marked cables. Make sure to lift up the locking tabs with a plastic tool. The CMOS and speaker cables are disconnected by pulling on the white connector at the end of the cable.

  37. Remove two (2) M2x5 screws that hold the metal bracket over the USB-C connector, then set it aside.

  49. The screen can be opened by prying around the edges of the frame and then removing four (4) M2x2 or smaller screws to replace the LCD screen.
