This article covers the installation and configuration of Arch Linux on a Lenovo Thinkpad T14s (AMD) Gen 1 laptop.
For a general overview of laptop-related articles and recommendations, see
Laptop
.
Firmware
Updating the firmware using the
fwupd
utility works as long as all the relevant options are enabled in the BIOS (Enable Windows Update UEFI Update). A BIOS update Bootable CD ISO that is OS agnostic may be downloaded from
https://pcsupport.lenovo.com/
.
The UEFI BIOS can also be updated without using
fwupd
; see
Flashing BIOS from Linux#Bootable optical disk emulation
for more information (and heed the warning at the top of the article). A charged battery and AC power are required for a successful update. Avoid having any addons/docks plugged in when performing the BIOS update.
Secure boot
Warning
As of August 2021 deleting
Secure Boot
keys and installing your own keys (for example by using
KeyTool
) will brick the device.
This is a problem that is similar to one which
has been reported on some other Lenovo laptops
and is likely due to a faulty firmware. If the device is stuck in a boot loop after replacing the Secure Boot keys, the only way to repair it is by replacing the mainboard of the device. Hopefully, the issue will get fixed with a firmware update in the future.
Fingerprint sensor
The fingerprint sensor 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.
If the fingerprint reader is not detected by
fwupd
but is detected by
lsusb
you will need to reset the fingerprint reader in the UEFI.
Backlight
Note
If
quiet
kernel option is set you may have to add
fbcon=nodefer
or systemd-backlight will fail on boot
Backlight works correctly by manipulating the values, between 0-255, inside
/sys/class/backlight/amdgpu_bl0/brightness
or using a backlight managing utility.
Smartcard reader
Seems to work and read cards. Following instructions from
smartcards
.
Power management
Enabling S3 sleep
For Suspend to work as expected, in the UEFI setup, under
Config > Power
set the option
Sleep State
to
Linux
.
Reboot and verify whether deep sleep is available, as explained in
Power management/Suspend and hibernate#Changing suspend method
.
Mobile broadband
The only supported WWAN card is the Fibocom L850-GL, a PCIe card without any Linux drivers (and most probably never will get any, it is an Apple owned chipset now). All the existing WWAN workaround involve flashing a Sierra Wireless (Qualcomm) WWAN to escape the BIOS whitelist by enumerating slowly. This however does not work in the T14s, the card is entirely disabled and not even visible in
lsusb
. It is possible that the USB lanes are disabled on the M.2 port.
There exists an
alpha-quality driver
for the Fibocom L850-GL. The L860 is not proposed in the T14s AMD but is in the T14s Intel and a Linux mainline driver is being worked on by Lenovo for it. See
Xmm7360-pci
for more information.
Wireless
See
Lenovo ThinkPad T14 (AMD) Gen 1#Wireless
Microphone
The microphone may not be operational. A possible fix is to
blacklist
the
snd_pci_acp3x
module (to allow newer kernels to use
snd_rn_pci_acp3x
?)
Webcam
The webcam needs the
upd72020x-fw
AUR
USB 3.0 chipset firmware.
