Bluetooth adapter has no power

General system Newbie

I tried to use the following commands to solve the heating issues in my laptop
sudo powertop --calibrate and sudo powertop–auto-tune

now many things seem to be broken (themes etc) but the main issue is my bluetooth has stopped working, the bluetooth manager shows no power (“br-connection-adapter-not-powered”)

Is the bluetooth service running?

$ sudo systemctl status bluetooth.service

This was the output.

What is the output of this command?

$ rfkill list

Just to give a headsup, everything seemed to work perfectly before i used powertop for better power management and temperature issues. It seems only after using them this issue has been generated

Did you try turning the pc off and on again?

I’m not super familiar with powertop, but I’m pretty sure there are some bluetooth power settings in the config file. Personally I just use powerprofilesctl it ships with EOS and does a good enough job on my Nvidia laptop.

i did just now. now the bluetooth manager shows unknown error

the output of status has changes a little
