2nd-Gen MateBook X Pro (2019) Revealed in FCC Docs

Feb 24 MWC Update: turns out this is the all-new MateBook 14.

A 2019 successor to the Huawei MateBook X Pro is coming, and it’s looking good — at least in these documents from the U.S. Federal Communications Commission.

Annotated page of KLV-WX9 (2019 MateBook X Pro) label document from FCC, showing unique port selection and revised design.

The model in question is the KLV-WX9, codename ‘Kelvin’. See the original label document here. Read more about MateBook model codenames here.

Chassis

At first glance, the updated MateBook X Pro looks very similar to the MateBook 13’s bottom, with a wide air intake for a dual-fan cooling system. However, you can see that this is a more premium laptop: it has a machined aluminum unibody just like the current X Pro, while the MateBook 13’s body is composed of multiple, cheaper, mostly two-dimensional stamped aluminum sheets.

Measuring the body drawing to-scale, the new MateBook appears to be roughly 4mm wider and 7mm taller. So, we may be getting the webcam on the top bezel, or a slightly bigger (14″?) screen, or thicker bezels in exchange for more internal space, or none of the above — Huawei’s drawing may just be distorted.

Easily Disable Intel DPTF / IPF (Power Throttling) for Good

Important: this is no longer necessary for many laptops because ThrottleStop‘s “Disable and Lock Power Limits” option can override DPTF. If that doesn’t work, try the following.

If your CPU frequency is being reduced under load, even at low temperatures, you’re probably experiencing power throttling. Most of the time, you can solve this by disabling or raising the power limits, and disabling DPTF explicitly is not required. But sometimes, you need to disable Intel’s Dynamic Platform and Thermal Framework (now called Innovation Platform Framework), which tries to set the power limit dynamically on your behalf.

Your laptop may have an option to disable DPTF in the BIOS menu. If not:

Easy MethodManual Group Policy Method
  1. Download and extract NoDPTF. It’s a tool we made that modifies the registry in order to disable and “blacklist” DPTF/IPF devices. Here’s the repository on GitHub.
  2. Right click on RemoveDPTF.bat and run it as Administrator. This script disables all the DPTF/IPF devices so you don’t have to disable each manually in Device Manager. It also blacklists those devices using the Registry to prevent Windows from automatically reinstalling them.
  3. Reboot.

From now on, you should see a few disabled devices in Device Manager instead of DPTF/IPF devices in the “System” category.

If any DPTF devices are still present, please tell me their hardware IDs in the comments. (To check hardware ID: right click on the device, Properties, Details, select “Hardware Ids” in the drop-down menu.)

This method only works if you have Group Policy Editor (Windows Pro/Enterprise/Education, or using this hack in Windows Home).

  1. Open the Group Policy Editor.
  2. Go to Computer Configuration/Administrative Templates/System/Device Installation/Device Installation Restrictions.
  3. Open “Prevent installation of devices that match any of these device IDs“.
  4. Click “Enabled“.
  5. Checkmark “Also apply to matching devices that are already installed“.
  6. Click “Show“.
  7. Now you will enter the device ID of each of the DPTF-related devices. You can find them all by finding those devices in Device Manager/System Devices or by copying all the values from NoDPTF.reg.
  8. Click “OK” and “OK” again. You should see each of those devices become “Unknown device” in Device Manager. That means they are disabled.
  9. Reboot.

Keep in mind: the removal of DPTF will not inherently change anything until you raise the power limits using ThrottleStop or Intel XTU.

Warning: if your computer can’t cool its CPU VRM properly, then raising the power limits may cause it to suddenly shut down. If that’s the case, you need to give the VRM more cooling like I did here.

Reversion Instructions

  1. In Registry Editor, delete HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions.
  2. Reboot.

MateBook X Pro Survey Results: Most User-Modified Laptop!

How common are the issues plaguing the MateBook X Pro? And how many users have taken solving them into their own hands? This past month, I surveyed 309 visitors of Reddit.com/r/MatebookXPro and BradsHacks.com about their experience with the critically acclaimed Huawei laptop.


The majority of the surveyed users reported having a loose or rattling touchpad. Based on my understanding of how the touchpad is installed into the frame, I suspect that all units actually have this issue to some degree and some users just don’t perceive it as an abnormality. After all, loose trackpads are quite common in laptops.

Subjective Perception

Similarly, the issues with temperature and various types of noise are inherently subjective. For example, the same laptop can be considered too hot or loud by one user yet be completely acceptable for another. Some people are more sensitive to the buzz of coil whine and work in quieter environments, so they could notice the coil whine much more than others.

Huawei Revises MateBook X Pro with Speaker Distortion Remedy

Previously, the Huawei MateBook X Pro’s speakers would produce distortion because they rattled against the laptop body. As shown in this unit purchased in November, Huawei has addressed this issue by putting small pieces of foam underneath the speakers. Is this because they saw my original post, where I both pointed out the issue and introduced this very solution? We may never know.
