Note: As this model includes no physical recovery media, it's highly recommended to create a Windows reinstallation flash drive just in case using the recovery media creation tool included with your preinstalled Windows system.

Due to the fact that there is no optical drive, you need to install Arch from USB stick.

The Arch install media will happily boot under UEFI, so it is recommended to disable legacy boot in the system setup utility. If legacy boot is needed for some reason, it does work fine as well.

Booting using Gummiboot works perfectly. Again, if legacy boot is needed, GRUB-BIOS is perfectly functional as well.

Hardware Configuration

To fully support all hardware in X, one needs to ensure that the following driver packages are installed:

Nearly everything works fine with no special configuration. The sensors (accelerometer, gyroscope, magnetometer, ambient light sensor) don't seem to be recognised yet.


The pen digitiser should be recognised by the wacom driver out of the box. The capacitive (touch) digitiser works with the same driver, but is not recognised as compatible by default. To fix this, add Atmel to the first MatchProduct entry in the wacom driver configuration file:

Section "InputClass"
    Identifier "Wacom class"
    MatchProduct "Wacom|WACOM|Hanwang|PTK-540WL|Atmel"
    MatchDevicePath "/dev/input/event*"
    Driver "wacom"

Everything should work after a reboot.

If you find yourself frustrated by the capacitive digitiser while trying to use the pen, you may have interest in the thinkpad-helix-utilsAUR package. It contains a script, helix-toggle-touch, which will toggle the capacitive digitiser on and off with a simple command.

Screen Rotation

If you have both digitisers configured through the xf86-input-wacom driver, they will automatically rotate with the display and you can use a simple command like xrandr --output eDP1 --rotate left to rotate the screen with ease.

There is also Magick Rotation, which is supposed to automatically rotate the screen based on input events, but it only seems to respond to docking/undocking the tablet.


If the Broadcom USB device isn't showing up, you likely need to turn it on with echo 1 > /sys/devices/platform/thinkpad_acpi/rfkill/rfkill0/state
