## Installation

Use `F1` or `Fn+F1` to enter UEFI/BIOS setup utility. You must disable Secure Boot to be able to boot from the installation media.

## Secure Boot

See Secure Boot for general setup.

Note: Replacing the Microsoft's platform keys with your own (by running `sbctl enroll-keys`) is safe and does not brick the laptop, but it is not known as of 2023-06-01 what exact impact on internal devices it causes or if there is any device firmware validation at all.

## Fingerprint reader

The fingerprint reader is built-in on the button and does not require pressing the button itself.

`27c6:530c` requires a proprietary driver which can be obtained here libfprint-2-tod1-xps9300-binAUR.

`04f3:0c4d` works out of the box and doesn't require a proprietary driver.

`27c6:55a2` is currently in the works of reverse engineering.[1][2]

The fingerprint reader doesn't work well with the default fprint because the sensor works by touching the sensor, not swiping the finger over the reader, hence it requires libfprint-tod-gitAUR. It is very precise: fprint only saves five finger samples which are not enough for different finger placements.

## Screen rotation

Install iio-sensor-proxy for automatic screen rotation to work.

## Power and Performance management

Note: Tools like tp_smapi or tpacpi-bat do not work with this device.

To tweak CPU power and performance preferences, see Dell XPS 13 2-in-1 (9365)#Reduce throttling as Lenovo's and Dell's Intel CPUs use the same interfaces.

To set the Battery Conservation Mode, see Laptop/Lenovo#Battery conservation mode

Desktop Environment specific tools can be found over the internet to set everything up with GUI.

Fan control readings do not work yet and managed by the BIOS by default.

Offline USB charging can be turned on(1) or off(0) with:

    # echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/usb_charging

## Platform profiles

ACPI platform profiles can be managed manually via sysfs(5) at `/sys/firmware/acpi/platform_profile` or automatically via tlp or power-profiles-daemon. Available profiles can be viewed with `cat /sys/firmware/acpi/platform_profile_choices`.

## HuC firmware

To enable HuC firmware loading for offloading media decoding functionality, see Intel graphics#Enable GuC / HuC firmware loading.

## Lenovo integrated pen and touchscreen (Wacom)

See Graphics tablet for general installation procedure.

libwacom does not have a tablet definition for the `i2c:056a:5269` device ID yet[3].

It is possible to add your own definition instead so other programs such as gnome-control-center can recognize and configure the tablet:

    /usr/share/libwacom/isdv4-5269.tablet

    [Device]
    Name=ISDv4 5269
    ModelName=
    DeviceMatch=i2c:056a:5269
    Class=ISDV4
    Width=12
    Height=7
    IntegratedIn=Display;System
    Styli=@isdv4-aes;

    [Features]
    Stylus=true
    Touch=true
    Buttons=0

## Function keys

Since the release of Linux 6.5, the `ideapad-laptop` driver has been updated to support extra hotkeys found on this laptop.[4]

To control `FnLock` programmatically:

    # echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/fn_lock

To control keyboard backlight (from 0 to 2) :

    # echo 0 > /sys/class/leds/platform::kbd_backlight/brightness
