This article covers the installation and configuration of Arch Linux on a Lenovo T495s laptop.

For a general overview of laptop-related articles and recommendations, see Laptop.

## Fingerprint reader

The fingerprint reader works: use fwupd to install the latest firmware for "Synaptics Prometheus Fingerprint Reader".

fprint has more details on how to setup the fingerprint, for PAM-based authentication for example.

## Backlight

Backlight works correctly by manipulating the values, between 0-255, inside `/sys/class/backlight/amdgpu_bl0/brightness` or using a backlight managing utility.

`systemd-backlight@backlight:acpi_video0.service` requires masking as it seems to be triggered and fails on boot.

## Firmware

Although the fwupd utility works to update some of the components, Lenovo does not support BIOS updates for the T495s yet. A BIOS update Bootable CD iso that is OS agnostic may be downloaded from Lenovo support[1].
