    Tools needed

    • Various size philips
    • Prying tool / dead credit card
    • Toothpick / regular tweezer
    • Various size flathead
    • Marker / masking tape
    • I HIGHLY RECOMMEND LIQUID METAL THERMAL PASTE, SUCH AS CONDUCTONAUT OR LIQUID ULTRA
    • Thin Electrical tape [recommend: Scotch super 33+]
    • Thermal pad [varying size, estimate around 0.5mm, 1mm, or 1.5mm] OR easier method -> K5 Pro Thermal material
    • Rubbing alcohol and cleaning material
    • Patience

    Tip

    • Label every screw position
    • Label longer screws to distinguish position from one another
    • Be slow and careful



    1. Turn laptop over, take apart all SSD, RAM, HDD.

    Don't get your filthy skin oil on the top of SSD or the thermal pad, stick the SSD to the thermal pad for safekeeping.






    2. Take out all screws on bottom, you can remove the rubber shield by tweezer or toothpick

    3. Remove ODD, this is held on by one screw.

    4. Take off speaker bar and disconnect data cable

    5. Take off keyboard, pry along the edges of top cover assembly. Find the battery cable and unplug before continuing to step 6

    6. Disconnect speaker data cable and eDP screen cable.

    [​IMG]





    7. Disconnect wifi cable and the white connector next to it. White cable is on left of card and black cable on right of card.

    [​IMG]








    8. Take off screen by removing 6 middle screw and 2 outer ones.

    9. Unscrew this one from the PCH, it is not necessary to take off the other screw.

    Here is a look on the PCH thermal solution, it has thermal pad.

    10. Disconnect power switch board

    11. Take off screws off this usb board and wiggle it out

    [​IMG]






    12. Take off fan screws.

    13. Label and disconnect every single screw and cable connection on motherboard

    sorry no pic on this one, pretty self-explanatory






    14. Wiggle motherboard out, remove screws to access chip and repaste!

    CPU / GPU CORE USES THERMAL PASTE
    THE OTHER COMPONENT CAN USE K5 PRO OR THERMAL PADS
    I don't think it is necessary to use thermal pad or K5 pro on the other components, they're fine as is and you can put it back together no worries.

    Your heatsink shape will be different according to model.

    As you see, the GPU VRM is not covered on my unit. That is the only component you need to use thermal pad or K5 Pro - ONLY IF THE FACTORY PASTE DOESN'T HAVE GOOD CONTACT, OTHERWISE LEAVE AS IS.

    [​IMG]








    K5 Pro applied on VRM

    [​IMG]


    Good pressure on VRM and K5 Pro

    [​IMG]









    Put electrical tape around the silicon, MAKE SURE ELECTRICAL TAPE DOES NOT TOUCH THE TOP OF SILICON. This will protect your vital component from the liquid metal thermal paste.

    Apply a blob of liquid metal, use the included qtip or spreader with circular motion to spread the liquid metal around. YOUR OBJECTIVE IS TO EVENLY "PAINT" THE SURFACE OF THE SILICON! Use gentle pressure!

    Here are some misc parts that @triturbo will find interesting.

    [​IMG]




    Fan anti-dust hole, not sure how this works.

    [​IMG]

    [​IMG]

    [​IMG]

    [​IMG]





    The vapor chamber over the CPU.
    CPU thermal solution is only 2 heatpipe, but on top is soldered the vapor chamber, it acts as a thermal "bridge". The CPU or GPU can offload heat to either side.

    [​IMG]

    [​IMG]







    Dust hole, part of anti-dust feature on fans.

    [​IMG]

    [​IMG]






    Speaker bar

    [​IMG]

    [​IMG]










    The power button interface is very poorly designed!

    [​IMG]

    [​IMG]










    Seems like a gap, can use tape to seal and prevent hot air flowback.

    Great guide! Do you happen to measure the size of these fans? Specifically the thickness and the rotor's diameter? I was eager to see that dust-free system. Wonder how efficient it is. Is it dusty around you?

    The vapor chamber solution looks interesting. Is that a copper shim between the GPU core and the vapor chamber? If so, they are losing on conductivity, so I don't quite get the decision behind it. Also - thermal bridge? I though that it covers both cores, but I guess they did their thermal math better than me :)

    You know...You were pretty lucky right? You still had the battery plugged in. You might want to point out to users to unplug that first once the keyboard assembly is removed. :)

    Oh well, would buy couple of them to check them out, if they ever hit the market.

    Ah yeah, but I think it's ok as long as you're properly grounded.



    Sorry :(

    For vapor chamber, it'a a bulge and not shim. The nvidia heatsink also resemble this on the desktop gpu.

    All the grounding in the world is not going to stop metal to metal contact from the screw drivers my friend....:)

    But totally awesome job! :D

    Also, the bios chip seems to be located right on the opposite side of the the cmos battery....The one that can't be reset unless you remove the whole board. Grrrrrrrrrrrrrrrrrrrrrrr!

    More bad news....3000 mhz ripjaw xmp does not work. And you have to take the machine apart to reset it.

    Very convenient :D I think that they were among the first to introduce push-button reset on their desktop MoBos...

    Yeah, that's how it usually is, but it looked like a shim to me. Anyway, that's awesome.
