Installation
Use
F2
to enter BIOS. You must disable Secure Boot to be able to boot from the installation media. UEFI boot mode (OS Optimized Defaults) is working fine and can be used.
Firmware
Support for firmware updates through
fwupd
is supported. But Lenovo so far only provides firmware updates for devices where Linux is officially supported (Thinkpad/ThinkCentre series). As this is not a device of these series, do not expect firmware updates through
fwupd
.
Firmware updates through
fwupd
are supported (but unavailable) for the following components:
System firmware (Lenovo)
UEFI (Lenovo)
NVM Express Solid State Drive (Sandisk)
Suspend
Suspending to system sleep state S3 is not available on the Intel 11th gen mobile CPUs found in this laptop
[1]
. Forcibly suspending the device to S3 leads to it locking up. If this happens, you can restore your device to working order via a hard reset. To hard reset the Yoga 9, press the power button for at least 15 seconds.
More recent Linux kernels will instead detect and use system sleep state S0ix automatically. Depending on your specific hardware configuration you may experience fast battery drain when using S0ix. The likely cause is a bug in the firmware of the SSD (WDC PC SN730 SDBPNTY-1T00-1101, Firmware (
fwupd
): 11170001) that keeps it in the D0 state (fully on state). This keeps part of the platform in an inefficient S0ix state with some PCIe busses running on full power. To verify whether this bug impacts your specific setup, use the
S0ixSelftestTool
. Discussion around this bug and potential solutions can be found in
Talk:Lenovo Yoga 9 14ITL5
.
If you wish to eliminate battery drain, but still want to benefit from the fast wakeup times of S0ix, consider using
Suspend then Hibernate
(
Power management/Suspend and hibernate#Hibernation
). You can configure your machine to hibernate after sleeping in S0ix for a specific duration of time by
configuring the lid close action
to
suspend-then-hibernate
and tuning
HibernateDelaySec
.
Accelerometer
You must use
iio-sensor-proxy-git
AUR
instead of
iio-sensor-proxy
for the accelerometer to work. It is important to note, that the trigger for tablet mode does currently not work. At least within KDE you can enable automatic screen rotation only globally.
Audio
This laptop requires
Sound Open Firmware
in order for the soundcard to work.
Thermals
It is recommended to enable
OS Optimized Defaults
in the BIOS settings. Enabling this option improves the thermal properties of the system tremendously. Without it,
thermald
will not throttle the system before it is near its critical temperature. You may want to select the appropriate cooling strategy in the BIOS (intelligent/performance/power saving).
Power management
Tools like
tp_smapi
or
tpacpi-bat
do not work with this device.
To set the Battery Conservation Mode see
Laptop/Lenovo#Battery conservation mode
.
Wireless devices
Rfkill
reports two additional devices (
ideapad_wlan
,
ideapad_bluetooth
). Blocking or unblocking these devices has no effect. Instead use the devices:
phy0
for Wireless LAN
hci0
for Bluetooth
Function keys
Fn lock only locks for
F1
to
F12
. The
Ins
and the
PrintScreen
buttons still require the use of
Fn
even with Fn lock enabled.
The keys
Fn+Ins
and
Fn+PrintScreen
only function with
ideapad-wmi-fn-keys-dkms-git
AUR
.

The physical key has a symbol on it, which describes its function.
systemd-logind handles this by default.

Tablet Mode
Installing
yoga-usage-mode-dkms-git
AUR
will generate the necessary events to trigger tablet mode.
