Accessibility
The UEFI offers one mode of operation,
GUI
.
The GUI can be navigated to some degree via the keyboard.

Right
arrow keys to move the selection and
Space
to activate.
Note
Blind users may want to request the help of a sighted person to change UEFI settings
Firmware
fwupd
does not support this device yet and likely is not going to.
Lenovo support page for this model only provides
.exe
installer for UEFI updates. There is no option in the UEFI itself to select a binary blob from USB stick.
CPPC is enabled in UEFI in the latest BIOS update, otherwise the kernel falls back to the legacy
acpi_cpufreq
driver for
CPU frequency scaling
. This is resolved in Linux 6.12.

Battery charge threshold is supported.
Updating UEFI
Note
Make sure your device is on AC power
A workaround
is to install the UEFI from
Windows PE
. A common choice is
Hiren's Boot CD
. Boot into the live environment, download
the update file
and install it.

Warning
Installing with Microsoft vendor keys is recommended as there are not any reports indicating if it is fully safe yet. No Option ROMs in the below output provides some confidence, however it is up to the user as you risk bricking your device.
The firmware only allows restoring Microsoft vendor keys, and does not have any options to install any custom keys. To install keys you can use tools such as
sbctl
. No Option ROMs appear to be present as per testing with:
# cp /sys/kernel/security/tpm0/binary_bios_measurements eventlog
# tpm2_eventlog eventlog | grep "BOOT_SERVICES_DRIVER"
See
Secure Boot
for more details.
Issues
Headphones
There is an issue with using headphones through the 3.5mm jack when using
PipeWire
. When headphones are connected, little to no sound may be audible. To resolve this, adjust the
Bass Speaker
volume to 100% using
amixer
when the headphones are plugged in. After that, the regular volume control in PipeWire will function as expected.
amixer -c 1 sset 'Bass Speaker' 100%
The
Bass Speaker
volume must be adjusted every time headphones are connected.
Note
The
amixer
command is provided by the
alsa-utils
package.
Laptop Built-in Speakers
Another issue with sound on Lenovo Yoga Pro models (specifically on
14IMH9
and
14AHP9
and
14IAP7
) is sound card pin mixup. It manifests as follows: changing volume does not seem to have any effect, but when setting it to 0% volume does actually turn off. To fix volume control you need to create
/etc/modprobe.d/mysound.conf
with row below and reboot:
options snd_sof_intel_hda_generic hda_model=alc287-yoga9-bass-spk-pin
The quirk is know in linux kernel, e.g. see the constant
ALC287_FIXUP_YOGA9_14IAP7_BASS_SPK_PIN
in
kernel realtek patches

Supposedly its been fixed with
kernel patch
but I needed the manual modprobe option.
Panel Self Refresh issues
PSR can cause flickering and random freezes/crashes, see
AMDGPU#Frozen_or_unresponsive_display_(flip_done_timed_out)
for details.
DC_DISABLE_PSR = 0x10
is part of
DC_DEBUG_MASK
from
drivers/gpu/drm/amd/include/amd_shared.h
.
