BIOS

Updates

Automatic (Linux Vendor Firmware Service)

In August of 2018 Lenovo has joined the Linux Vendor Firmware Service (LVFS) project, which enables firmware updates from within the OS. BIOS updates (and possibly other firmware such as the Thunderbolt controller) can be queried for and installed through fwupd.

Enabling S3

The BIOS has two "Sleep State" options, called "Windows" and "Linux", which you can find in at Config -> Power -> Sleep State. The Linux option is the traditional S3 power state where all hardware components are turned off except for the RAM, and it should work normally. The Windows option is a newer software-based "modern standby" which works on Linux (despite the name). One possible benefit to the Windows sleep state is faster wake up time, and one possible drawback is increased power usage.

Reboot and verify whether S3 is working by running:

# dmesg | grep -i "acpi: (supports"

You should now see something like this:

 [    0.230796] ACPI: (supports S0 S3 S4 S5)

Audio

Install the latest linux-kernel and sof-firmware. Out of the box, without sof-firmware, the internal speakers as well as the microphone are not working.

Note: This method lead to working speakers (at least two out of the four), but without a working microphone.

Add to your kernel parameters the option snd_hda_intel.dmic_detect to 0, for example by adding it to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grubd:

/etc/default/grub

...
GRUB_CMDLINE_LINUX_DEFAULT="quiet ... snd_hda_intel.dmic_detect=0"
...

After running update-grub as root and rebooting, the speakers should be working.

Hidden Fn-Keys

Fn+B	Break
Fn+K	ScrollLock

Configuration

Many of the configuration options can be found in Lenovo ThinkPad X1 Yoga (Gen 4) and Lenovo ThinkPad X1 Carbon (Gen 7), as the X1 Carbon 7 and X1 Yoga 4 have a very similar structure to the X1 Yoga 5.
