BIOS
At bootup, the BIOS settings page is entered via the
F2
key.
In the BIOS settings, the model name can be seen in the
Main
tab,
Secure Boot
can be disabled from the
Security
tab and
boot mode
can optionally be switched between
UEFI
and legacy.
There is no known option to disable the discrete NVIDIA GPU using the BIOS (only have "Hybride Graphics" and "Discrete Graphics"), there may be one present after unlocking the advanced options.
Video
Backlight
Power Down Nvidia Card
Blacklist nouveau drivers, reboot, and run:
# echo 'auto' >> /sys/bus/pci/devices/0000:01:00.0/power/control
Multihead
External displays using the USB-C ports only seem to function using the proprietary NVIDIA driver.
If you enabled Discrete Graphics mode
If you enaled Discrete Graphics mode in BIOS,you cannot control the backlight via the function keys or in "Battery and Brightness" section in control center. Because the brightness is controlled by
/sys/class/backlight/nvidia_0/brightness
.
To recover the functionality of
Fn+F5
and
Fn+F6
, you can change the acpi actions via creating the following files in the

Reboot afterwards.
Power Management
One can change the power mode with the default
Fn+Q
key.
Battery conservation mode is available. It will charge the device to 60% when charge falls below 50%, extending the life of the battery. It can be activated by running the following command:
# echo 1 >/sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
You can also install
ideapad-cm
AUR
to change the status conveniently.
Keyboard
Keyboard is working out of box. There is no RGB settings.

F9
(Favorite key),
F11
(tab switching key) and
F12
(Calculator key), since ACPI key functions is not defined.
