Altough I'm not using Ubuntu, I'm also affected by this problem. Battery level doesn't seem to be a cause since this just happened to me and I had charged to 100% before.
I'm not sure if this is a linux problem or a firmware problem since i t will remain until battery is replugged. Also, this time I charged to 100% using windows 8, and then shutdown the PC. Later I turned it on to boot Arch Linux and the fan went full speed (while booting the kernel), and battery led blinking orange. I powerd off the laptop again, and the led kept blinking. Then I powered it on again and the led keeps blinking but the fan speed has returned to normal. Replugging the power cord results in the battery led blinking between green and orange, instead of the black/orange I previously got. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to upower in Ubuntu. https://bugs.launchpad.net/bugs/1088146 Title: Asus n56vz battery state is wrong or battery not charging at all. Status in “upower” package in Ubuntu: Confirmed Bug description: I have an ASUS N56VZ notebook. There are some bugs I have mentioned and they are known on ubuntu forums. Sometimes I am getting strange results in battery power state, that are not even close to be accurate. So bugs are: 1) Then I am turning on the notebok with not enough power (3% for example) the fan is going to it`s full speed (no CPU loading at all) and the power indicator shows that power is insufficient. Plugging the power adapter didn`t solved the problem - it was not charging and notebook soon turns off. 2) As I described above, I can`t feed the notebook sometimes (especially on low battery level). 3) I am getting the strange battery state result: sometimes it looks, that it`s charging very slow. Am am working about a hour and my power level just rised from 30 minutes to 40 minutes. 4) I am not sure about this bug, may be it`s a hardware one, but then I turned notebook off with plugged in power adapter, it was not charged at all for the whole night! http://ubuntuforums.org/showthread.php?t=2084696 - here is a proof, that I am not alone ))) ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: upower 0.9.17-1build1 ProcVersionSignature: Ubuntu 3.5.0-19.30-generic 3.5.7 Uname: Linux 3.5.0-19-generic x86_64 ApportVersion: 2.6.1-0ubuntu6 Architecture: amd64 Date: Sun Dec 9 13:18:17 2012 ExecutablePath: /usr/lib/upower/upowerd InstallationDate: Installed on 2012-11-30 (8 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MarkForUpload: True ProcEnviron: 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/1088146/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
