Firmware

Updates

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 UEFI has two Sleep State options, called Windows and Linux, which you can find in at Config > Power > Sleep State. See Power management/Suspend and hibernate for the explanation of the various sleep states.

Reboot and verify whether deep sleep is available, as explained in Power management/Suspend and hibernate#Changing suspend method.
