Installation

To access the boot menu and UEFI, use F1. Disable Secure Boot from the UEFI.

Firmware

fwupd does not support this device yet, but it may still detect the laptop as a ThinkPad T460s and try to update its firmware if the installed firmware is very old.

To update the firmware on the device, get the latest bootable CD and follow the steps in Flashing BIOS from Linux#Bootable optical disk emulation.

TrackPoint

Sometimes the TrackPoint stops working and dmesg reports a stream of garbage when it is touched. Removing and probing the kernel module solves the problem:

# rmmod psmouse
# modprobe psmouse

Video

With default configuration, tearing is apparent when playing videos. See Intel graphics#Tearing.

Fingerprint reader

Works using https://github.com/3v1n0/libfprint. Bug tracker for fingerprint sensor: https://gitlab.freedesktop.org/libfprint/libfprint/issues/54

Power management

If the device has unusually high CPU usage in idle then it might be an acpi firmware issue. On Windows this behaviour stops after a regular update. On Linux you can workaround by disabling whatever device is interrupting excessively.

Find the interrupting source:

$ grep . -r /sys/firmware/acpi/interrupts

This might output something like this:

...
/sys/firmware/acpi/interrupts/gpe34:   30289   enabled  <-- this causes many interrupts
/sys/firmware/acpi/interrupts/gpe35:       3   enabled
...

Disable it:

# echo "disable" > /sys/firmware/acpi/interrupts/gpe34

Now the CPU should idle at 0-2% usage.

Unfortunately you have to do that on every startup. A systemd service can do that automatically for you.

Create /etc/systemd/system/disable-interrupts.service:

[Unit]
Description=Disable acpi interrupts
[Service]
ExecStart=/usr/bin/bash -c 'echo "disable" > /sys/firmware/acpi/interrupts/gpe34'
[Install]
WantedBy=multi-user.target

Then enable the disable-interrupts.service systemd unit.
