For the line

%wheel ALL=(ALL) NOPASSWD: /usr/bin/tee /sys/bus/platform/drivers/ideapad_acpi/VPC????\:??/conservation_mode

It returns

I'm on Fedora 35 stable up to date.

Hello again!
Since Gnome 42 is shaping up and starting to become available on many distros, it would be nice if this extension was updated to support it.

Many thanks in advance!

Thanks!

I installed this extension on my Lenovo ideaPad Y700-15ISK with Ubuntu 20.04 and it is not working properly.

When the extension is on, the leaf appears next to the battery, but when I 'toggle' it, it doesn't deactivate the conservation mode.

I have dual boot with Windows 10 and I realized that if I set the 'conservation mode' in Windows, the battery configuration is the same in Ubuntu.

May be 'Lenovo Vantage' tools in windows overrides this extension?

Hello, I've installed the extension on a Lenovo IdeaPad Gaming 3 laptop (GNOME 40/Fedora 34 beta) and nothing happens when I press "Turn Conservation Mode On" in the System menu. I even created the /etc/sudoers.d/ideapad file as instructed.

For now it is only available through plain ACPI calls,
(e.g. # echo '\_SB.PCI0.LPC0.EC0.VPC0.DYTC 0x0012B001' > /proc/acpi/call),
which is totally uncomfortable.
Here is the link to brief description on this calls, confirmed working on IdeaPad 5 15ARE05 and Yoga Slim 7 Pro 14s ARH 2021.

Greetings,

I'm using openSUSE Tumbleweed and have applied all of the settings in the README including %wheel instead of %sudo, but the toggle in the extension is not working. It is only able to show me if conservation mode is enabled or disabled, but nothing more. I know that the ideapad_laptop module is loaded for two reasons:

1. This extension is working and the reason why I don't want to use it is because it prompts me with a password prompt each time I want to switch Conservation Mode on and off. Yours doesn't.
2. Changing the value between 0 and 1 in /sys/bus/platform/drivers/ideapad_acpi/VPC2004\:00/conservation_mode enables/disables Conservation Mode respectively.

Expected behavior:
Extension should enable and disable Conservation Mode on-demand from GUI.

I was able to change conservation mode, however, it doesn't work after I upgraded the kernel to 5.12 (via mainline).
I tried the commands but got Input/Output error...

$ ls /sys/bus/platform/drivers/ideapad_acpi/
bind  module  uevent  unbind  VPC2004:00

$ echo "0" | sudo tee /sys/bus/platform/drivers/ideapad_acpi/VPC2004\:00/conservation_mode > /dev/null

OS: Ubuntu 20.04
Kernel: 5.12.1

I've been using this extension in Fedora 35 Beta and it works as it should with GNOME 41.
I could test it because I disabled extension version validation.

There seems to be an extension like this, just for information.

Hi again laurento.

After finally fixing all the config, the extension works like a charm... Or so I thought...

I left the laptop without charging to drop the battery down to 50% and toggled the conservation mode.

The leaf appeared instantly but the battery keeps charging until 100%!!

Shouldn't stay in conservation mode around that 50-60% without charging?

Currently, it is required to tinker with the sudoers file in order to use this extension.
With polkit (pkexec) instead, by default the extension would work out of the box: it would require inserting the password each time, but it's possible to be configured so that it wouldn't be necessary anymore (the configuration procedure would be different, of course).

It's been a few days since I installed Debian 12 on my Lenovo IdeaPad 3i.
The extension never worked on this Debian. I already checked /etc/sudoers.d/ideapad
I also checked /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode
Everything seems to be correct

I tried echo "ideapad_laptop" | sudo tee -a /etc/modules
I tried another Kernel version...
But nothing works

I tried and works on Fedora 37, Arch Linux and Ubuntu 22.04 and 22.10

I can turn Conservation Mode on or off with sudo bash -c 'echo 0 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode or sudo bash -c 'echo 1 > /sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode but not with extension.

These are some errors I encountered when trying to use the extension:

I found out that using a file monitor on sysfs does not work, so it might as well be removed.

A workaround would be to to call _syncState as final action in _setConservationMode, as well as on opening the menu.

This would also warn users that the desired setting could not be applied (for example when the permissions are not setup properly)

I am not a GNOME extension developer, so this idea might be irrelevant/not possible. I have thought that this extension could add new keyboard settings in the settings app. Specifically managing switching fn lock mode (4.18+). Maybe also toggle USB always on in power settings (5.12+).

In Extension.js at line 82:

if (this._item.state != active) this._item.toggle(); // Emits a 'toggled' signal

A 'toggled' signal is emitted, triggering an infinite loop where _syncStatus and _setConservationMode are called again and again.

Changing the said line to prevent emitting a 'toggled' signal solves the issue :

this._item.setToggleState(active); // Does not emit a 'toggled' signal

I've been combing through the extension and have found out that it seems to be one step behind what is actually in the conservation_mode file when using the extension on my Lenovo Yoga C940 with Fedora 34 and GNOME 40. This means that the icon is displaying when conservation mode is actually off and the label for the toggle is 'On' when it will turn conservation mode off and vice versa.

I have also noticed that the first time I click the toggle, it will toggle, but neither the indicator nor the toggle label will change. I suspect that this is where the issue lies as on every subsequent toggle it will in fact both toggle and update the indicator and label, effectively putting them one step behind.

I would perhaps hazard a guess at the fetching of the status getting old information, although I do not know how that would come to be. Or that the icon and label are updated before the actual toggle, but that would seem unlikely as the sync should trigger on a change-event?

Sorry to bother you.

Best regards.

Edited metadata and it has no label

Uninstalled GNOME DE recently and had forgotten about this extension, now I'm on cinnamon with battery at 59%. That is to say, I forgot to deactivate the energy conservation mode🌚

When I activate the conservation mode, the battery stabilizes at its current level, so the charge/discharge cycle works fine, but it doesn't initially discharge to the optimal level of 55-60%.

This extension supports all sorts of features including this one, however it is not compatible with Gnome 45: https://github.com/AzzamAlsharafi/ideapad-controls-gnome-extension
