+# lenopow
+
+> Lenovo Ideapad/LEGION battery conservation mode on Manjaro Linux
+
+**lenopow** allows managing Lenovo Ideapad's/LEGION's firmware on the battery
+and shifts between the usual charging thresholds from 95/100% to 55/60%.
+In some cases, not charging the battery to 100% constantly may improve
+the overall lifespan of the battery. This setting is suggested for a system
+that is always plugged into the AC adapter.
+
+## Instalation
+
+The standard `make install` routine is used.
+
+The following additional variables are supported:
+
+- `DESTDIR` -- determines environment for staged installs,
+- `PREFIX` -- determines where the script will be installed (default: `/usr/local`).
+
+## Requirements
+
+The script requires the following to run:
+
+- `bash`
+- `linux >= 4.14`
+
+## Usage
+
+Run: `lenopow [operation]`
+
+| Operation         | Description                                      |
+| :---------------- | :----------------------------------------------- |
+| `-h`, `--help`    | Show help message.                               |
+| `-v`, `--version` | Show script version.                             |
+| `-s`, `--status`  | Show battery protection status.                  |
+| `-e`, `--enable`  | Enable battery protection (charge level 55-60%). |
+| `-d`, `--disable` | Disable battery protection (charge level 100%).  |
+
+## License
+
+This simple wrapper script, with a definitely too big name, is licensed under the Unlicense - see the [LICENSE](LICENSE) file for details.
