Same problem with the T420, T420 and T440 I have had. The T440 I couldn't get more than 3 hours out of it compared to 7-8 on windows. They had the PM set up properly. Powertop shows loads of things constantly waking the devices up.
- UncleSlacky 9y agoHave you tried TLP? It was originally written specifically with Thinkpads in mind, but can be used on any laptop now: http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-management.html http://linrunner.de/en/tlp/docs/tlp-linux-advanced-power-man...
