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.
Should you have enabled the VMD controller in the BIOS, you must add vmd to the mkinitcpio.conf array before you regenerate the initramfs. See also .
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 . 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, this leads to a battery drain of ~0.4%/hour, or ~5% over 12 hours . If you wish to further reduce battery drain during sleep you can use hibernation as the action when the lid is closed.
Accelerometer
You must use instead of 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.
Sound
This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.
Thermals
It is recommended to enable 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, ). Blocking or unblocking these devices has no effect. Instead use the devices:
- for Wireless LAN
- for Bluetooth
