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 .

Touchpad

The touchpad works out of the box since kernel version 5.12.6.

Wireless

This laptop is available with either Intel AX200 or Realtek RTL8822CE, both work well on modern kernel. Realtek has pretty bad performance when using Bluetooth A2DP together with 2.4 GHz Wi-Fi network. Use either 5 GHz wireless network or external Bluetooth adapter for better speed when using Bluetooth audio devices.

Power management

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 battmngr AUR it is possible to control both Battery Conservation and System performance modes.

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:

Set it to Intelligent Cooling mode:

Set it to Extreme Performance mode:

Set it to Battery Saving mode:

To verify your setting:

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

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 .

To verify your setting:

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 .

To verify your setting:

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

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

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.

Lenovo IdeaPad 5 14are05

This article or section does not follow the Laptop page guidelines.

The IdeaPad 5 14are05 is a 14-inch Lenovo AMD Renoir (Ryzen 4000)-based laptop.

Contents

Hardware Support

BIOS can be accessed by pressing F2 at the Splash screen. The 15-inch model has BIOS updates that are compatible with DOS, so its BIOS can be flashed without Windows (see Flashing BIOS from Linux#FreeDOS). Unfortunately, the update files for this model require Windows. In theory, Windows can be installed on a USB drive through woeusb AUR .

Video

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

Sound

Sound works with PulseAudio in linux out of the box.

Microphone

The internal microphone is properly recognized and working for linux >=5.8rc3 as long as the snd-acp3x-rn kernel module is loaded.

If the internal microphone is no longer recognized on linux >=5.10, you may need to add the following to the kernel parameters:

Wireless

It is available with different wifi chips but they should work out of the box. Bluetooth also works with the btusb module, and remote audio playback with A2DP works through pulseaudio-bluetooth (see Bluetooth headset on setting it up).

Touchpad

The touchpad works almost as expected starting from linux 5.9-rc1. It is still random whether it will work or not after going out of suspend mode, but in that case it is an easy fix: just add a keyboard shortcut for the touchpad toggle and you should be able to make it work again.

For older kernels, it is important to make sure that the BIOS is updated to the latest version (atm 1.06), otherwise it is possible that the touchpad will not even be discovered let alone work. If touchpad device is found it is still possible that it will not work (either right after startup or after going out of suspend mode). In this case a new cold start might help (sometimes a reboot might be enough).

Additionally, while there is no explicit option to disable the touchpad in the BIOS, some option combinations in the BIOS can make the touchpad inaccessible. Thus, if you are running on linux 5.9 or newer and you still have issues with this module, try checking your BIOS settings first.

Display

The brightness works for linux >=5.7.6.1, since the patch to fix brightness has been merged. The xbacklight utility provided with xorg-xbacklight only works with Intel drivers (see Backlight#xbacklight), but you can use its replacement from acpilight to increase and decrease brightness levels. Since the latter requires different permissions for the files in /sys/class/backlight/ to control the backlight brightness levels, you should set up a file in /etc/udev/rules.d/90-backlight.rules containing:

You would also need to add your users to the video group.

In order to preserve the brightness level when resuming from suspend, you should add the following kernel parameter to your bootloader’s configuration file:

Issues

Suspend issues (S3 sleep fix)

Note: suspending works as expected out of the box starting from linux 5.14-rc1 (that is, AMD’s s2idle is now properly supported, although s3 sleep can still be achieved with the method below). So for kernels = 5.14, the solution is provided below. Note that this does not work in kernels from 5.11 to 5.13. Original solution is described on reddit.

About issue

Windows has introduced a new sleep mode a.k.a. Modern Standby. It is supposed to be more like a smartphone’s deep sleep, which lets the system keep the wifi active and check for emails without needing to fully wake up.

For some reason, this new S0ix sleep mode only works if BIOS does not advertise support for the traditional S3 suspend-to-RAM sleep state. So Linux will do suspend-to-idle sleep, which results in bigger energy consumption.

Some systems have a «Sleep Mode: Windows / Linux» switch in the BIOS to turn S3 support on or off. This is unfortunately not the case for this Lenovo laptop.

Solution

• Get acpidump and iasl, provided by the acpica package.
• Dump all your ACPI files into a directory:

• Decompile the DSDT table

• Patch the decompiled DSDT table (dsdt.dsl). Use this patch for Linux cpio archive

• Copy created cpio file to boot:

• GRUB needs to boot the kernel with a parameter setting the deep sleep state as default. Edit /etc/default/grub and add the following:

• Regenerate the GRUB configuration:

as a result in the /boot/grub/grub.cfg for the corresponding menu entry(ies) one should be able to find lines that look similar to: initrd /boot/acpi_override

• Reboot
• To verify that things are working:

• Do not forget to set your system to go into ‘deep’ sleep

• Now try new suspend. Power led should have a slowly pulsing light.

Tips and tricks

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:

Set it to Intelligent Cooling mode:

Set it to Extreme Performance mode:

Set it to Battery Saving mode:

To verify your setting:

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

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

STMD	QTMD	Mode
0x0	0x0	Extreme Performance
0x0	0x1	Battery Saving
0x1	0x0	Intelligent Cooling

Rapid Charge

Make sure you have set up acpi_call .

To verify your setting:

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 .

To verify your setting:

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

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

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 calls (#Rapid Charge and #Battery Conservation) will not do this for you. So it is possible to get the state where both battery conservation and rapid charge modes are active.

How to update the Lenovo IdeaPad 5 15ARE05 BIOS from Ubuntu Linux.

As stated in this thread https://askubuntu.com/a/1251189/70172, Brightness issue on the Lenovo IdeaPad 5 15ARE05 with Linux can only be solved after a BIOS update.

I bought this laptop with FreeDOS, and so I expect to be able to update the BIOS WITHOUT Windows.

LENOVO, please pay attention and give more consideration to your Linux Users.

Re: Ideapad 5 15ARE05 BIOS update on Linux

I used this article as a guide, but also added some notes to it.

1. Install innoextract
2. Use it to unpack the executable that Lenovo provides
3. If no «.cap» file is extracted from that but you get another single executable file, run that executable under Wine (with wineconsole) with an «/ext» flag, e.g. «E7CN33WW.exe /ext»
4. Use the «.cap» file to update the system firmware with the fwupdate tool, e.g. «sudo fwupdate -a 09166175-35f4-4a03-b45b-ef6fc908468a

Don’t just copy & paste any instructions, read the article. You don’t want to brick your laptop.

I also run a kernel >= v5.7 to get support for the AMD chipset & graphics. I use Pim’s script to manage that.

Re:Ideapad 5 15ARE05 BIOS update on Linux

I’m running Ubuntu and update BIOS using Windows 10 installation from USB. Not too much practical for Linux users, but it works:

• Download Win 10 ISO
• Install a virtual machine with Win 10 in KVM on Linux
• Run the virtual machine
• Create «Windows To Go» USB disk using Rufus tool — it’s a live distro Win 10 on USB
• Restart your Linux and boot to Windows 10 from USB
• Download and install BIOS update from Lenovo support page
