Bluetooth suddenly stopped working

I was listening to some music and the headphones just suddenly stopped working. So I tried to see what’s up, and I can’t enable bluetooth anymore.

bluetoothctl list returns empty. Running bluetoothctl power on returns No default controller available. Also tried these with the LTS kernel and got the exact same results.

I’m not sure what’s up. Note that it’s a pretty old laptop (~8 years), so might just be a hardware failure. Wanted to verify if that’s indeed what’s up before I buy a dongle. Please let me know what I can check if it’s indeed a hardware issue.

Some hardware issue? It stopped while listening music?
Maybe battery ran out? :wink:

Another idea could be try to use the LTS kernel and see if that works.

The headphone didn’t die, the laptop simply can’t turn on Bluetooth anymore. And as I mentioned, I already tried the LTS kernel, but to no avail.

Edit: It started working again in the morning, but has now stopped again. So it’s probably a hardware issue.
