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.
Lenovo may in the future provide cabinet files that can be directly installed with fwupdmgr. Check for Linux .cab files from the Lenovo ThinkPad X1 Carbon (Gen 8) driver website.
- Make sure the AC adapter is firmly connected to the target computer.
- Launch Terminal.
- Move to the directory where the cabinet file was placed.
fwupdmgr install xxxxxxxx.cabto schedule firmware update.
- Restart the system.
- The computer will be restarted and the UEFI BIOS will be updated.
The BIOS has two Sleep State options, 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.
