I think the problem is related to the huge difference between energy-full and enegry-full-design (see attached upower.dump). The same numbers are reported by acpi -V. The battery is a 55Wh (7300mAh) in a Samsung Ativ9 940X3G laptop (productID: AA-PLVN4AR). I've: - Tried booting a live-usb with an old ubunut (14.04) with the same result - Run the "Smart battery calibration" from BIOS with no difference Thanks, Niklas ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: upower 0.99.2-2 ProcVersionSignature: Ubuntu 3.19.0-20.20-generic 3.19.8 Uname: Linux 3.19.0-20-generic x86_64 ApportVersion: 2.17.2-0ubuntu1.1 Architecture: amd64 CurrentDesktop: Unity Date: Sun Jun 14 18:34:00 2015 InstallationDate: Installed on 2015-04-24 (51 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Release amd64 (20150422) SourcePackage: upower UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upower/+bug/1465033/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
