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.

Manual

Download the latest BIOS image from the Lenovo Thinkpad X1 Yoga 3rd Gen downloads page. Obtain geteltoritoAUR and run geteltorito.pl -o bios-update.img xxxxxxxx.iso on the downloaded ISO file to create a valid El Torito image file, then flash this file on a USB drive via dd like you would flash Arch installation media. For further information see flashing BIOS from Linux.

The ThinkPad X1 Yoga supports setting a custom splash image at the earliest boot stage (instead of the red "Lenovo" logo), more information can be found in the README.TXT located in the FLASH folder of the update image.
