Yes, you can. Hint: redirect the output to a file.
The installation process doesn't apply any settings, just copies files and enables the services but doesn't start them immediately. Uninstall just removes the files and services. You can remove the remaining config files with
sudo apt-get purge tlp tlp-rdwYou may check the installed files at any time with
dpkg -L tlp tlp-rdwIf you uninstalled with remove instead of purge you will see the following files
/etc/default/tlp
/etc/init.d/tlp
/etc/NetworkManager/dispatcher.d/99tlp-rdw-nm These files alone are not functional and should do no harm to your system.

Symptom data
Upon installing tlp & rebooting, wired ethernet cannot connect. removing tlp does not help. The system still does not connect.
tlp-statvia Gist for all cases of 1. Can't, it's tlp that causes the network not to work.Expected behavior
upon installing tlp & doing a (warm) reboot, eg after update, the wired network should connect as before installation of tlp.
Actual behavior
wired network cannot connect. curious observation : removing tlp does not work. It still cannot connect.
my thots : there are 2 problems here;
conclusion,
if, however, i absolutely do not install tllp, the system works beautifully. Between reboots, i can connect to ethernet no matter how many times i reboot, regardless also of whatever kind of update or software installation.
Steps to reproduce the problem
OS : Ubuntu 16.10
This porblem only manifests itself on certain hardware. I have 2 other laptops which do not have this problem, but they are generation 2 CPUs. This is a gen 6 (skylake). Here are my hardware specs Manufacturer : Acer Product name : Aspire E14 model : E5-474G-53G4
