Issues
HDMI sound suffers from the PulseAudio limitation described in
PulseAudio/Examples#Simultaneous output to multiple HDMI / DisplayPort outputs
. The workaround described there works (manually setting the
module-alsa-sink device
in
/etc/pulse/default.pa
).
Errors with pointer devices when flipping/rotating the screen manually with randr.
In kernel 5.12 keyboard backlight support was
added
to the
ideapad_laptop
kernel module
but it does not seem to properly support the multiple keyboard backlight brightnesses provided by the keyboad (off|dim|bright). This can cause problems setting keyboard brightness with
software
.
Occasionally the touchscreen and touchpad do not work after boot. The workaround for this a reboot. The cause and fix is unknown. The
dmesg
log is below:
[   15.619747] i2c_hid_acpi i2c-WACF2200:00: HID over i2c has not been provided an Int IRQ
[   15.619776] i2c_hid_acpi i2c-MSFT0001:00: HID over i2c has not been provided an Int IRQ
[   15.619809] i2c_hid_acpi: probe of i2c-WACF2200:00 failed with error -22
[   15.619846] i2c_hid_acpi: probe of i2c-MSFT0001:00 failed with error -22
The
Synaptics 06cb:00be
fingerprint sensor is not supported out of the box by libfprint. To work around this, you can use
libfprint-2-tod1-synatudor-git
AUR
along with
libfprint-tod-git
AUR
, to get this fingerprint reader working.
Touch screen setup
The touchscreen and pen is recognized by the
input-wacom
driver. For setup information look at
Wacom
.
Tablet/Laptop mode
Install
yoga-usage-mode-dkms-git
AUR
to get device recognition for the lid switch. This creates the device
/dev/input/by-path/platform-yoga-event
, on which
libinput
or
detect-tablet-mode-git
AUR
can act.

Firmware
fwupd
does not officially support this device but it can still be used to apply uefi firmware updates.
[1]
Updating bios
Warning
Flashing motherboard BIOS is a dangerous activity that can render your motherboard inoperable! While the author of this article has successfully run this procedure many times, your mileage may vary. Be careful!
Note
All bios settings will be reset including the boot entry so make sure you can set up the boot entry for your install after the bios update. See
efibootmgr
for more information.
The commands
fwupdate -l
and
fwupdate -i
may no longer work (error below), but
fwupdate -a
still works.
(fwupdate:10680): FuPluginUefiCapsule-WARNING **: 12:47:47.256: SMBIOS BIOS Characteristics Extension Byte 2 is invalid -- UEFI Specification is unsupported, but /sys/firmware/efi exists: SMBIOS not supported
Segmentation fault (core dumped)
Pre update
Install the
innoextract
,
udisks2
and
fwupd
packages.
Download bios update exe file.
[2]
Procedure
Run the following commands:
Extract the bios
.cap
file:
$ innoextract file.exe
Get the GUID number of your system firmware for the next step. You should get something that looks like example below:
# fwupdmgr get-devices
system-firmware type, {e20bafd3-9914-4f4f-9537-3129e090eb3c} version 22315982 can be updated to any version above 22315981
device-firmware type, {e3be8073-66a6-4bf6-966a-c0d58b486c40} version 1 can be updated to any version above 0
device-firmware type, {c85ba1bc-54a7-4aab-9337-eed4746bf09f} version 0 can be updated to any version above 4294967295
Schedule the update for the next system reboot, using extracted
.cap
file:
# fwupdtool install-blob /path/to/file.cap e20bafd3-9914-4f4f-9537-3129e090eb3c
Note
If your ESP path is not located at
/boot/efi
use
--esp-path=
to specify path.
Note
Make sure the device is connected to a power source before rebooting.
Reboot if there are no errors.
Enter the bios settings and move
Linux-Firmware-Updater
to the first option in the Boot Priority Order menu.
Save and exit and the update should begin.
Warning
Do not interrupt the bios update in any way doing so may result in a bricked device.
Note
During the update the device may beep, turn on and off, and appear unresponsive, this is normal.
When the update completes it will boot into the boot menu. At this point it is safe to interact with the device again.
Post update
Disable secure boot in the settings to be able to boot into Linux.
If your boot loader is not detected, boot into a usb with Arch and use
arch-chroot
to reinstall your
boot loader
or use
efibootmgr
to
create a boot entry
.
Secure boot
This device supports custom importing keys using
efi-updatevar
(
efitools
).
Note
Uefi administrator password must be set to enroll custom keys.
Lenovo diagnostics
The Lenovo diagnostics can be accessed by pressing
F11
during boot. The Diagnostics contains tests for the motherboard and memory. Results of the tests can be stored onto a USB stick.
Firmware settings
AMD PSP
The AMD Platform Security Processor setting in the firmware can be used to disable or enable
TPM
functionality.
Disable built-in battery
This option temporarily disables the battery for servicing(e.g. changing ssd). To enable the battery again, connect the charger to the device.
Accessing the bios
The firmware settings and boot menu can be accessed by pressing the novo button(located on the right side of the headphone jack) with a pin or paperclip when the device powered off.
Power management in firmware
The System Performance Mode Option can be set to Extreme Performance, Intelligent Cooling, Battery Conservation. These settings can also be controlled from the OS, see
#System performance mode
.
Issues
OneKeyBattery bug
There is a
bug
with the OneKeyBattery setting which can cause problems powering on the device. It effects bios versions older than eecn25ww. To fix this, disable the OneKeyBattery setting in the bios or
update
the bios to version eecn25ww or newer.
