Einleitung

The display assembly is featured as a wide touchscreen, and holds an integrated camera.

Replacement of this assembly is fairly simple, though must be handled with care.

It is possible to replace components of the display assembly itself, however, it is a task that should be sought after by those who have the correct tools to replace such components.

Werkzeuge

Schritt 1

Remove the eight M2 5mm screws that secure the base cover using a Phillips #0 screwdriver.

Schritt 2

Loosen the three captive screws that secure the base closer to the hinges.
Do not attempt to remove the three captive screws! You need only to loosen them. They're supposed to stay on the base cover.

Schritt 3

Carefully pry the base cover using an iFixit opening tool in the crevice near the hinges. Guide the pick along the edges and slightly lift upwards as you go along.
Do not start from the speaker end of the edges when opening, or you may cause further damage to your device!

Schritt 4

Carefully remove the base cover from the laptop.

Schritt 5

Remove the screw holding down the small bracket for the wireless card using a Phillips #0 screwdriver.
Remove the black wired connection from the port over the black triangle.
Remove the wire with the white marking from the port above the white triangle.
Pull the Wi-Fi card out of its slot.

Schritt 6

Gently remove the I/O cable.

Schritt 7

Remove the fan cable from the motherboard.

Schritt 8

Remove two 3 mm screws that secure the fan using a Phillips #0 screwdriver.

Schritt 9

There is a little piece of tape/sticker on the fan that connects it to the heat sink. Gently remove this.
Lift the fan off the palm rest assembly.

Schritt 10

Loosen seven 3 mm captive screws securing the heatsink to the motherboard using a Phillips #0 screwdriver.

Schritt 11

Lift the heatsink off the motherboard.

Schritt 12

Ensure that you have your device opened flat at a 180 degree angle. This will make removal easier.

Schritt 13

Locate the ribbon cables for the assembly on the right hand side marked "MB1" and "MB2."
The "MB1" ribbon is locked with a copper/brass colored handle that must be lifted upwards. Then you can remove the ribbon by pulling it away from the socket.
The "MB2" ribbon is locked in its socket with a black latch. Using a non-metallic precision tool (such as tweezers) lift the latch and pull away the MB2 cable.

Schritt 14

Remove the two screws holding down the assembly on the right hand area using a Phillips #00 screwdriver.

Schritt 15

Remove the screw protecting the endpoints of the NIC cables and NIC chip using a Phillips #0 screwdriver.
Gently pull away the cabling from the NIC chip.
The wires can be removed without removing the heat sink, though this is not advised if you are not familiar with the layout.
