Install TLP

Extend the life of your battery by limiting it.

1. Update Hosts content

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 "/^127\.0\.1\.1\s\+/s/\S\+$/$(hostname)/" /etc/hosts
