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.

IdeaPad 5 15are05 — elan touchpad not working on 20.04 nor on 18.04

I bought a Lenovo IdeaPad 5 15are05 yesterday and installed Ubuntu 20.04 on it. Problem is, the touchpad doesn’t work.

I’ve also tried 18.04 and even Debian 10, but the only OS it works on is Windows.

I’ve looked through many fora and I found nothing that helped me. However, I did find some commands and I think you will find these outputs interesting

Even though it says «Touchscreen», I know for a fact that this is my touchpad. How do I know this? Well, when I go to a terminal using ctrl+alt+f3 , and I try to use my touchpad, it outputs this:

elants_i2c i2c-ELAN0001:00: unknown packet 0e 00 04 03 03 meaning that I’m touching it. That value changed on different actions, for example, it becomes 01 on ‘releasing’ the touchpad.

This means that the touchpad is listed under ELAN0001, which the «Touchscreen» is listed under as well. I don’t think it’s that weird that it says it’s a touchscreen, because they’re very similar.

xinput outputs this:

The touchpad should be listed under Virtual core pointer, but it isn’t.

I would really like to know a fix for this, since I need the touchpad to work and I don’t want to buy a new laptop, so please help me!

5 Answers 5

It seems not to be possible to blacklist elants_i2c driver, as it is a built-in kernel module for Ubuntu:

so there is a faster way than compiling the kernel. Just create a SystemD unit like the below:

and create /usr/local/bin/touchpadfix file as follows

and then make it executable, enable and start the unit with the following commands:

and touchpad should start to work immediately!

I found the solution, big shoutout to dl3it on Ideapad 5-15ARE05: Touchscreen not working | Lenovo Forums. (Note: it says touchscreen, but that’s just the name of the touchpad I guess. It works fine.)

The problem is that the kernel does something wrong with the drivers. To fix this, you will have to install a mainline kernel and configure it yourself.

First off, install dependencies by executing this on a command line:

Then, download kernel 5.6.x or 5.7.x (x can be any integer, I used 5.7.1 and it has been tested on 5.6.14 and 5.7.0-rc7) from source (via kernel.org). Once on kernel.org, click on [tarball] for the kernel you want.

Extract everything as you would do with any other .tar.gz file.

Then, move to the linux-5.6.x or linux-5.7.x directory in a command line.

Execute sudo make menuconfig and navigate to Device Drivers → Input device support → Touchscreens → Elan eKTH I2C touchscreen.

Once there, change the asterisk to an m by hitting enter and then typing the m .

After that, use the left and right arrows to change the selected option in the bottom to «save» and hit Enter . Then, you will want to save it as .config (which it should default to).

Now still being in the same directory, execute this command:

sudo make -jx && sudo make modules_install -jx && sudo make install -jx

(Change x to the amount of threads your CPU has. Leaving out this option will make this take a long time.)

This will take some time, but after it’s finished, you will want to make sure your PC will boot on the new kernel. To do that, execute:

sudo update-initramfs -c -k

(Change to the kernel version you just installed, for example 5.7.1 .)

Then, fix the grub config by executing:

And then reboot and your touchpad should work just fine!

NOTE: websites I used and didn’t mention before:

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 have same laptop running same OS.

Updating Kernel helped me with the issues of Screen Brightness and also the HDMI started working too. However my Touchpad still does now work.

2. Ubuntu kernels to chose from:

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
