Schritt 1

Make sure to power down and turn off your device before proceeding with the repair.
Flip your laptop over so that the backside is facing you.

You should also disable the internal battery in the BIOS first too.

Schritt 2

Using a Phillips #1 screwdriver, remove the eight screws securing the backplate.
Don’t try to force screws which won't come out. They are held in place by a stopper on the reverse side. This will not prevent you from removing the backplate.

Only the bottom left and right screws can be pulled out. Don’t try to force the others.

Schritt 3

Using the metal spudger, wedge it in the seam where the backplate meets the front plate and run the tool along the seam to separate the backplate.

Schritt 4

Remove the back panel from the device.

Schritt 5

Use the Phillips #1 screwdriver to remove the four screws securing the fan to gain access to the processor.

Schritt 6

Lift the fan assembly to gain access to the thermal paste, from here the thermal paste can be wiped away and replaced.

I saw a video on youtube where thermal paste was placed on both the silicon chiplets of the cpu. In this picture; it looks like only the left cpu is getting thermal paste which i believe is an error.

I had a machine that was thermal throttling / overheating so I added thermal paste to both silicon chiplets.

Please comment if someone else has any further ideas.

Also, do not forget to clean off the old paste from the heat pipe/heat sink surface as well.
