The
Mechrevo WUJIE 14X
series encompasses several retail models featuring different processors and aesthetics. At least three variations are known to exist:
Mechrevo WUJIE 14XA
: Powered by an AMD Ryzen 7 8845HS processor.
Mechrevo WUJIE 14XA Blizzard Edition
(or 暴风雪,
Baofengxue
in Chinese): Also powered by an AMD Ryzen 7 8845HS processor.
Mechrevo WUJIE 14X
: Powered by an Intel Core Ultra 7 155H processor.
The former two models share identical hardware specifications, with the only distinction being their colorway.
This page primarily focuses on these first two models.
Installation
Disable secure boot
Secure Boot
is enabled by default. Since the installation medium does not support it, press
Esc
repeatedly during startup to access UEFI setup and disable it.
Ethernet controller
The RJ-45 Ethernet controller requires installation of
tuxedo-yt6801-dkms-git
AUR
.
Tip
If a wired network connection is required during the installation process, consider
building a custom Arch Linux installation medium
that includes the necessary kernel module. This can be accomplished using another machine that is already running Arch Linux.
Accessibility
The UEFI interface is a generic version from AMI (American Megatrends) that can be controlled with either a keyboard or a mouse, which should also make it relatively straightforward for OCR apps to parse.
To switch boot devices, repeatedly press
Del
during startup to display a boot menu. This menu can be navigated using the arrow keys, and a selection can be made with
Enter
.
Note
Nevertheless, considering that Mechrevo does not specifically focus on accessibility, it is recommended that the OS installation be performed with the assistance of a sighted user.
This laptop is not equipped with diagnostic LEDs.
Firmware
fwupd
supports updating the UEFI CA (UEFI revocation database).
BIOS / EC
Official support site (Chinese only)
provides BIOS/EC firmware upgrades.
Note
However, the update utility runs only on Windows, which may necessitate the temporary installation of
a dual-boot system
to apply firmware updates.
SSD
The firmware of the pre-installed Crucial SSD can be upgraded. See
Solid state drive#Crucial
for details.
Tip
As an alternative to the bootable ISO,
micron-storage-executive-cli
AUR
provides a command-line method for firmware upgrades and also offers additional SSD information.
Hardware control
On Windows, the pre-installed UWP application,
Mechrevo Control Console
, is used to control features such as keyboard backlighting, performance/thermal profiles, as well as battery charging speed and limits. Under Arch Linux, various workarounds are available.
Platform drivers
Because WUJIE14X utilizes a Tuxedo-compatible motherboard, the necessary platform drivers can be acquired by installing either
tuxedo-drivers-nocompatcheck-dkms
AUR
or
mechrevo-drivers-dkms
AUR
(
Recommended
).
These packages provide essential drivers for controlling various peripherals, and are also a dependency for some of the tools mentioned below.
Unified control
TUXEDO Control Center
(
tuxedo-control-center-bin
AUR
) can be used to manage most hardware features, including the keyboard backlight, fans, battery modes, and performance profiles. For those seeking an all-in-one package, it is the best available alternative to
Mechrevo Control Console
.
Note
However, when using the
amd-pstate
governor, there is an unconfirmed bug where its daemon process,
tccd
, may repeatedly reset the governor to
performance
. This leads to
increased power consumption on battery and reduced battery life
.
If you encounter this issue, consider the alternative solutions for each module detailed below.
Fan
tuxedo-rs
provides the ability to control cooling fan speeds and configure fan curves.
You can install
tailor-hwcaps
AUR
to view fan speed and temperature sensor data, and install either
tailor-cli
AUR
or
tailor-gui
AUR
(GUI) to set the fan curves.
Platform profile
Platform Profile, also known as
Fn Mode
or
Thermal Mode
, is used to control the system's overall power consumption and thermal performance. On WUJIE14X, the Platform Profile includes three levels:
Office / Quiet
,
Gaming / Balanced
, and
Turbo / Performance
.
Note
Unlike on other devices, the Platform Profile on WUJIE14X is implemented through
more than a dozen hardware calls
initiated directly from userspace. Consequently, no single system interface exists to switch the profile. Each hardware call must be reverse-engineered and replicated from scratch.
Aside from using TUXEDO Control Center, there is currently no other reliable method for switching between the profiles.
Battery charging mode
The battery control interface is implemented under
/sys/devices/platform/tuxedo_keyboard/charging_profile/
by the
#Platform drivers
.
To view the available charging modes:
$ cat /sys/devices/platform/tuxedo_keyboard/charging_profile/charging_profiles_available
high_capacity balanced stationary
To set a charging mode:
# echo
mode
> /sys/devices/platform/tuxedo_keyboard/charging_profile/charging_profile
Note
There is a widely reported but unresolved
issue
that setting battery charging mode doesn't take effect on some models.
Discussion
.
Keyboard backlight
The keyboard backlight has three brightness levels:
off
,
low
, and
high
. The state can always be cycled using
Fn+F6
.
At present, no known software interface exists to control the backlight. Consequently, there is no straightforward method to implement features like automatic backlight (de)activation.
Note
Reverse-engineering
has shown that the automatic backlight activation (e.g., on keypress) and timeout features on Windows are implemented entirely in software by the
GCUService
service. This functionality is
not handled by the hardware
.
Facial authentication
The infrared camera on this laptop functions correctly. Install
Howdy
for facial recognition similar to Windows Hello.

. Further testing is required to confirm.
Troubleshooting
Wake up immediately from sleeping
After
suspending to idle
, the laptop might immediately wake up. You can disable certain wake-up signals from the Embedded Controller (EC) by adding the
kernel parameter
acpi.ec_no_wakeup=1
.
