The only heatsink in this laptop is this big metal plate. In most laptops, a fan or two blow directly through a stacked-fin heatsink in a process called forced convection cooling. In the X Pro, heat spreads across the metal plate with the heatpipes' help, warming up the air inside the laptop. The small fan exhausts all this hot air and brings in new cool air using negative air pressure. It also generates some, but not enough, airflow across the heatsink plate.
The miserably small fan can spin at nearly 9,000 RPM, but the bar under it (where a heatsink with fins would usually be) is just one of the WiFi antennas.
The fan is the model BAZA0504R5H made by Asia Vital Components and rated at 5V 0.5A. This means it could theoretically use 2.5W when spinning at max speed (which happens to be around 8800RPM).
Look at how thin the fan is!
The fan has a sealed bearing.
The fan motor is 3-phase with 6 poles.
The copper base plate for the CPU.
Behind the keyboard is a pyrolytic graphite sheet to spread heat more evenly across the keyboard area.
See the motherboard with the heatsink off. The Nvidia MX150 GPU gets a thermal pad as if it were an Intel iGPU.
The back of the motherboard is covered with a plastic insulator film.
This is the motherboard's back with the plastic film removed.
The Nvidia MX150 (1D12 10W version) and its VRAM.
The motherboard has good component density. It's also the thinnest I've seen. The coil whine is insane on my unit.
The pop-up webcam's bottom and the springs for reducing the display cable's slack.
The WiFi card (Intel AC-8275) is non-replaceable.
Although the SSD is awkwardly under the heatsink, it can be wiggled straight out. I bought my X Pro on Taobao.com in China and it came with with a Samsung PM981.
The speakers under the speaker grill are tiny tweeters.
The tweeters fire upward through the grill, and they have a thin fabric filter cover.
Most of the sound comes from the bottom-facing speakers instead, which have much larger enclosures.
There is a cavity on each side of the touchpad, underneath the battery. The speakers could have extended into it like in the late-2017 HP Spectre X360 13t. Poor use of space? A little bit.
The hinges uses a simple rivet.
The display ribbon cables are similar to those of post-2016 MateBook Pros.
Huawei reportedly probed Apple suppliers to learn their display cable design (the one involved in #flexgate). As far as I know, this is the first laptop outside of MacBooks that houses the display controller inside the main body instead of the display assembly.
Unlike the MateBook X, there are no screws under the rubber feet. Instead, there are many plastic tabs that hold the back plate firm.
The back cover has many foam pads that press against the internals.
- Unscrew the screws.
- Use a guitar pick or similar tool to feel, locate, and lift the tabs.
- Pull the hinge side of the back plate first.
- No need to be gentle with the middle tab—it's spring loaded.
- The tabs near the touchpad side like to be slid out.

Hmmm
That does not seem to cool 8th u processor heat enough
How is it?
Great tutorial! When I was trying to remove bottom cover in my unit I noticed that something is keeping it attached to the rest of the computer in the very middle (after prying all of the plastic tabs on the periphery off). I didn’t dare to pull too hard. Did… Read more »
With the gap on the igpu any recommendations for another thermal pad or think it possible to use a combination of both to improve the temps? Awesome job on the teardown,
Have you tried installing ubuntu 18.04 LTS? I’m interested in getting this laptop if it works with ubuntu.
I noticed you’re showing a PM981 in the picture of the M.2 slot. Is that the drive that shipped with the Matebook?
What size are the screws on the bottom panel? Torx T5?
You mention that there’s too much space between the heatsink and the MX150 to use thermal paste, How thick/thin of a thermal pad do you recommend to use here?
If you remove the plastic film, is that permanent? Or can it be put back if needed? Also, how do the thermal pads stay in place on the back side of the motherboard? I thought they generally don’t stick, or are they thick enough to sit against the body without… Read more »
What size are the screws on the HeatSink ? It is very hard unthread ,…Unfortunatly , last night I destroyed one of volt head . So i cant detach heatsink from motherborad. Would you recommand a screw size for detaching heatsink . And i want to buy bolt for replace.… Read more »
Quite strange. Surely they’re not going to try to cool the MX150 model in the same way?
I see that actually is the MX150 model, but on doing some more research I think you may have missed one thing, there are actually fins under the heat plate before the fan, thus it is actively cooling fins, just by sucking rather than pushing. I don’t have one on… Read more »
Hi, I’m a little confused as to how to unplug the battery. Do I need to remove the heatsink first, and then unplug the multicolored cables? (Assuming the multicolored cables are the battery connectors. )
Any way to unplug the battery without dismantling the heatsink?
Hey I have a some small cracks in the screen of my matebook x pro. This prevents using touchscreen. I was wondering if you know a source for the part so I can fix it myself.
Interesting to note, the new retina Macbook Air also followed this concept of the fan not directly cooling fins –

Love this website, I will do the physical cooling mod in future for sure. It is winter now, the keyboard still get pretty hot. Is there any option to add some heat insulation layer at keyboard backside to prevent the heat ?
Wow! what’s the touch screen IC they used?
This has been a big help so far thank you!
But I have another problem: my hinge is really loose any suggestions to solve that issue?
Do you have a tutorial how to replace the LCD?
Thank you, super helpful!
Curious if anyone knows the thickness of this fan? thinking about building a new top plate with integrated heat sink fins inside the casing.
Hi Brad, Thanks for this guide, was able to open my matebook easily. I would appreciate if you can provide some advise, even just a guess on what you think is the problem with my laptop. It turns on but no display on screen, and the laptop will automatically shut… Read more »
Hello, please I have a Huawei matebook X pro and it’s just permanently dead and I want to fix it. But unfortunately I couldn’t find an engineer that can fix it here in Nigeria. So I want to refer it back to China and I don’t know the process. Please… Read more »

Hi, thank you for all of this information! I just had the hinge in my matebook come unglued like the reddit post you added a clip from to your 6 month deep dive youtube video. I am thinking that I patch it temporarily by removing the display and then using… Read more »
