I haven't yet figured out how to get TLP working nicely on my Ubuntu Thinkpad, as I had to scrap the broken battery the other day and replace it with a new one.
I've got my new battery in place now, but don't want TLP anymore. So I placed TLP_ENABLE=0
via sudo vim /etc/tlp.conf
(as described here). I rebooted but the thresholds are still in place, meaning my battery is at 80% and not charging. So now I've deleted TLP completly from my laptop, hoping that it would remove the threshold once and for all. But that isn't the case either.
So how do I remove the TLP settings completely?
