Asus G14 - Configuration to save battery

In this post I assume that you are using the Kernel from: https://asus-linux.org/guides/

Disable CPU Boost

Do every time you boot the laptop, or add a task in cron to do automatically at boot time.

echo "0" | sudo tee /sys/devices/system/cpu/cpufreq/boost

Display to 60 Hz

Disable dGPU (Nvidia) on demand

1. Install Supergfxctl

To do so in a correct way, we need to install first supergfxctl from https://asus-linux.org

2. Adding parameter to the Kernel

Add this line at the en of your Kernel options.

nvidia-drm.modeset=0

Reboot your system.

3. Enable NvidiaNoModeset mode to disable dGPU

supergfxctl -m NvidiaNoModeset

Now you can check that the dGPU is enabled running:

nvidia-smi

if you want to use only the Integrated GPU, run:

supergfxctl -m Integrated

You can also switch it graphically if you wish: https://asus-linux.org/third-party/

Fans speed Quiet

Hint 💡 (Battery live):

Limit the charge limit to about 60% (See the last image). I have been doing so for like 3 years, and from 76.0 Wh I have fully charged 56.1 Wh (73%)

I recommend you to check the battery consumption with: https://github.com/svartalf/rust-battop.

That is all :) . Enjoy
