ideapad-perf
Battery manager to handle system performance modes and charge modes through acpi_calls (for some AMD models of Lenovo IdeaPad). There is also a handy applet for your system tray.
Motivation
Similar to battmngr, but has been tested and confirmed to work on the following AMD models:
- IdeaPad 5 14ARE05 model 81YM. More information is available at the ArchWiki.
- IdeaPad 5 Pro 14ACN6 model 82L7. More information is available at the ArchWiki.
I have now built a separate branch that only includes the battery-related modes (Rapid Charge and Battery Conservation), as they should be more cross-compatible and may potentially work across Lenovo models with recent Intel CPUs too (testers welcome). An Arch package for this branch is available as a release here.
Note that the experimental branch of battmngr should also work on these devices.
Requirements
The original script requires the acpi_call module loaded for your kernel. In order to install and use the applet, you would also need ruby and ruby-gtk3. If you are using Wayland, please see the relevant note below.
Installation
You can download the script, make it executable, and add it to your path. You can run it with sudo, or you can install the supplied udev rule to make /proc/acpi/call writeable to all members of the wheel group.
There is a pre-built package for Arch Linux available as a release, including PKGBUILD and .install files if you want to build it yourself. If you don't need the systray applet for whatever reason, use the older release.

Usage
Syntax: ideapad-perf [OPTION] MODE
Options:
-h, --help see this help message
-p, --performance-mode set performance mode
-b, --battery-mode set battery mode
-c, --check verify both performance and battery mode
-vp, --verify-performance verify performance mode
-vb, --verify-battery verify battery mode
Valid performance modes:
ic, cooling Intelligent Cooling
ep, performance Extreme Performance
bs, battery Battery Saving
Valid battery modes:
rc, rapid Enable Rapid Charge (with Battery Conservation disabled)
bc, conserve Enable Battery Conservation (with Rapid Charge disabled)
off Disable both Rapid Charge and Battery Conservation
Note on Rapid Charge and Battery Conservation mode
As noted elsewhere, it is possible to activate both Rapid Charge and Battery Conservation on Linux. However, as this configuration is not obtainable using official Lenovo software on Windows and it would defeat the purpose of the Battery Conservation, I have chosen to explicitly prevent this - choosing one of the options will disable the other one first. If for any reason you need to achieve this effect, you can do so manually via the commands provided in the ArchWiki.
Note on the system tray applet and Wayland
Wayland and most modern GUI toolkits do not like system tray applets. There are libraries that provide similar functionality, but the Ruby bindings for them are non-existent or outdated and difficult to build. For now, there is a simple workaround - pass GDK_BACKEND=x11 before starting the ideapad-perf-tray.rb script, like so:
GDK_BACKEND=x11 ideapad-perf-tray.rb
