Installation
After completing the installation process, the boot partition is not found because NVMe support for Intel's Volume Management Device is not present by default. It is therefore necessary to add vmd to the MODULES section section in /etc/mkinitcpio.conf before regenerating the initramfs, see also .
Accessibility
The speakers do not work out of the box (see below), so in particular speech-aided installation is not possible.
Power management
In order to support "Windows Modern Standby", the BIOS does not advertise S3 sleep (suspend to RAM), as discussed in detail in this forum post.

Brightness keys
The brightness hotkeys only emit signals after resuming from suspend-to-RAM or hibernation, but not after (re)booting. This is because they depend on initialization by an ACPI method which is called when resuming from a sleep state but not on boot.
Speaker audio
Due to this bug, the speakers do not work without modification, but there is already a patch available. To apply the patch a tool called is required. This laptop also requires additional firmware in order for the sound card to work.
Install the alsa-firmware, , and packages and reboot to activate the firmware.
Save the following script and execute it with root privileges (e.g. ) to activate the speakers:
fix_audio.bsh
#!/usr/bin/bash while read l ; do hda-verb /dev/snd/hwC0D0 $l ; done <<END 0x20 0x500 0x24 0x20 0x400 0x41 0x20 0x500 0x26 0x20 0x400 0x2 0x20 0x400 0x0 0x20 0x400 0x0 0x20 0x4b0 0x20 0x20 0x500 0x24 0x20 0x400 0x46 0x20 0x500 0x26 0x20 0x400 0xc 0x20 0x400 0x0 0x20 0x400 0x2a 0x20 0x4b0 0x20 0x20 0x500 0x26 0x20 0x400 0x2 0x20 0x400 0x0 0x20 0x400 0x0 0x20 0x4b0 0x20 END
Fingerprint reader
The currently available fingerprint reader drivers for Linux do not support this model and because this is not one of Lenovo's Linux-certified machines, Lenovo will not provide Linux support for this device, either.
