Power Management

For a laptop, it's very important to properly configure the power management components.


sudo apt install tlp smartmontools acpi

Enable TLP

sudo systemctl enable tlp
sudo systemctl start tlp

Battery care

Uncomment these lines in /etc/tlp.conf


The service needs a quick restart for it to take effect:

sudo systemctl restart tlp

Add to /etc/pulse/default.pa
