## Firmware

Updating the UEFI works like described here: link ThinkWiki BIOS Upgrade/Using UEFI.

Lenovo has uploaded UEFI (and some other firmware) to LVFS, so you can also install it using fwupd.

## Fingerprint reader

See Lenovo ThinkPad T460p#Fingerprint reader; the X1 Carbon (Gen 4) and T460p share the same fingerprint reader.
