The Lenovo ThinkPad T14/T14s (Intel) Gen 2 was introduced in 2020. It features a 14" screen, 11th-gen Intel Core processors, and integrated Intel Iris Xe graphics. Everything seems to work pretty much out the box with kernel >=5.16.0.

To ensure you have this version, install the package dmidecode and run: 

# dmidecode -s system-version
ThinkPad T14s Gen 2i

Installation

Intel Turbo Boost

Check that Intel® Turbo Boost Technology 2.0 is enabled using 

$ cat /sys/devices/system/cpu/intel_pstate/no_turbo

An output of 1 means it is not enabled, so you will have to reset your BIOS to defaults. After doing that, running the command again should print 0. You should be able to see your CPU boosting way higher.

Suspend

The BIOS has two options for suspend: Windows and Linux (aka S0ix or "modern standby") and Linux S3. Both S0ix and S3 modes work on this system, but there is a bug that causes the trackpad to become laggy after resuming from S3 suspend.

Graphics

The onboard Intel Iris Xe graphics requires linux-firmware and also accepts these experimental kernel parameters: 

i915.enable_gvt=1 i915.enable_guc=0 i915.force_probe=!9a49 xe.force_probe=9a49

Screen Tearing might be visible on some desktop environments on this machines built-in display. Installing the xf86-video-intel package resolves the issue. Note that there might be caveats in installing the packages as discussed in Intel graphics.

Fingerprint reader

If using gnome and gdm, nothing other than installing fprintd is required to get the fingerprint reader working.

Sound

This laptop requires ALSA firmware for the internal sound card to work. Installing sof-firmware should be enough to have audio devices show up in Gnome's Control Center.

Mobile broadband

The Quectel EM120 WWAN (4G / LTE) is supported but needs an FCC unlock first.

You may also need to swap to the active physical SIM in case its stuck with no eSIM profiles. 

 # mmcli -m /org/freedesktop/ModemManager1/Modem/3 --set-primary-sim-slot=1

Accessibility

Note: Blind users should request the help of a sighted person to change firmware settings.

The UEFI BIOS defaults to classic text and phone OCR will work well. The BIOS has an option to use classic text display instead of graphical by navigating to Config followed by Setup UI and choosing Simple Text.

You can choose an external USB drive to boot off by pressing the Enter key, waiting 10 seconds followed by F12 to choose the device, usually found at the bottom of the list.

The default BIOS configuration will beep when normal startup is interrupted with F1 / Enter / F12 providing audio feedback.

Audio notifications (beep) for Lenovo Power On / TCG OPAL passwords can be enabled by navigating to Config followed by Beep and Alarm and enabling both Password Beep and Keyboard Beep.

Firmware

fwupd

fwupd supports updating the UEFI BIOS, NVMe SSD, and fingerprint reader (via the LVFS testing remote) out of the box.
