Installation

Before installing, disable Secure Boot in the BIOS. You can access the BIOS by pressing F2 at the Splash screen. The boot menu can also be accessed by pressing F12.

Video

X works natively with a current linux and xf86-video-amdgpu.

If you are having video issues with only the xf86-video-amdgpu installed, also install the AMD PRO package amdgpu-pro-oglp^AUR. See AMDGPU.

Wireless

You can use the native wireless driver with disable_aspm_l1=y and disable_aspm_l1ss=y Kernel module parameter in the rtw89_pci Kernel module is required in order for Wi-Fi to work.

For Bluetooth use rtw89bt-dkms-git^AUR with iommu=pt kernel parameter.

Function keys

No dedicated keys. The Fn functions on the keyboard are recognized and should work.

Fingerprint

Fingerprint needs libfprint-fpcmoh-git^AUR.

For installation see fprintd.

Power management

The following section was adapted from Lenovo IdeaPad 5 15are05.

Battery Conservation Mode is a feature that limits battery charging to 55-60% of its capacity to improve battery life, being most useful when the laptop tends to run on external power much of the time. It can be controlled with ideapad-cm^AUR. With ideapad2024-power-management^AUR or battmngr^AUR it is possible to control both Battery Conservation and System performance modes.

Note: It is worth noting that the Lenovo Vantage software for Windows when turning on Battery Conservation mode also turns off #Rapid Charge (if it was on). The same is also valid for the #Rapid Charge: turning it on will bring the battery conservation mode down. The aforementioned ACPI call #Battery Conservation will not do this for you, but #Rapid Charge will. So it is possible to get the state where both battery conservation and rapid charge modes are active if you activate #Battery Conservation after #Rapid Charge. You generally do not want this, as Rapid Charging puts more strain on the battery than regular charging, defeating the purpose of Battery Conservation Mode.

Kernel method

Set the ideapad_laptop.allow_v4_dytc=1 kernel module parameter.

To use without reboot:

# rmmod ideapad_laptop
# modprobe ideapad_laptop allow_v4_dytc=1

Restart power-profiles-daemon.service. Now power-profiles-daemon can do everything below.

System Performance Mode

There are 3 modes available: Intelligent Cooling, Extreme Performance and Battery Saving. To toggle it, you need to call some ACPI methods.

First install acpi_call (or acpi_call-lts for LTS kernel, acpi_call-dkms for other kernels) and load the kernel module:

# modprobe acpi_call

Set it to Intelligent Cooling mode:

# echo '\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x000FB001' > /proc/acpi/call

Set it to Extreme Performance mode:

# echo '\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x0012B001' > /proc/acpi/call

Set it to Battery Saving mode:

# echo '\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x0013B001' > /proc/acpi/call

To verify your setting:

# echo '\_SB.PCI0.LPC0.EC0.SPMO' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

As a result you get the value for the bit SPMO (either 0x0, 0x1 or 0x2).

# echo '\_SB.PCI0.LPC0.EC0.FCMO' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

As a result you get the value for the bit FCMO (either 0x0, 0x1 or 0x2). To interpret the results the following table can be used:

SPMO	FCMO	Mode
0x0	0x0	Intelligent Cooling
0x1	0x1	Extreme Performance
0x2	0x2	Battery Saving

Rapid Charge

Make sure you have set up acpi_call.

Turn on:

# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x07' > /proc/acpi/call

Turn off:

# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x08' > /proc/acpi/call

To verify your setting:

# echo '\_SB.PCI0.LPC0.EC0.QCHO' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

where 0x0 stands for off and 0x1 stands for on.

Battery Conservation

Similarly to the #Rapid Charge, make sure you have set up acpi_call.

Turn on:

# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x03' > /proc/acpi/call

Turn off:

# echo '\_SB.PCI0.LPC0.EC0.VPC0.SBMC 0x05' > /proc/acpi/call

To verify your setting:

# echo '\_SB.PCI0.LPC0.EC0.BTSM' > /proc/acpi/call
# cat /proc/acpi/call; printf '\n'

where 0x0 stands for off and 0x1 stands for on.

There is also an alternative way to control the conservation mode of the battery.

Known issues

Keyboard

The Keyboard will be disabled after waking up from hibernation, this bug fixes itself after an reboot. It is possible to permanently fix this bug by adding a i8042.nopnp kernel parameter, see .

Battery

The battery level may be capped above 100% (e.g. with i3-wm) which can lead to confusion.

Bluetooth

It seems pairing does not work correctly with pipewire-pulse. Try to connect to the Bluetooth device directly to pair with the device.

Onboard devices

Sometimes one or more onboard devices get soft locked, although it rarely occurs. To solve this, use rfkill (from util-linux):

# rfkill unblock your_device

Network Adapters not working

It seems external network adapters over the USB-C port do not work even if they did work on other Linux devices.

EFI Boot Manager fills up

The EFI Boot Manager fills itself with old boot entries which need to be manually deleted after changing the OS. For that you can use efibooteditor^AUR.
