Install TLP

Extend the life of your battery by limiting it.

1. Keep Hosts content up to date

If you have changed the hostname before, it may not have been updated in /etc/hosts. Correct this to avoid problems during installation.

# Specify the current hostname in /etc/hosts
sudo sed -i "s/^\(127\.0\.1\.1\s\+\)\S\+/\1$(hostname)/" /etc/hosts

2. Install TLP

TLP is a power management service.

# Debian, Ubuntu, Kali, Linux Mint (APT)
sudo apt install -y tlp tlp-rdw

# Red Hat, CentOS, Fedora, AlmaLinux, Rocky (DNF / YUM)
sudo dnf install -y tlp tlp-rdw
sudo yum install -y tlp tlp-rdw

# Arch, Manjaro (Pacman)

3. Continue with the installation
