You have been subscribed to a public bug: In Ubuntu 14.04 (Kernel 3.13.*) acpi battery status info worked fine and presented info in
/sys/class/power_supply/BAT0/ I tested 15.04 (Kernel 3.19.*) and noticed that there isnt any BAT0 in the above said folder anymore. I did some reading at https://lkml.org/lkml/2014/12/28/94 and came to conlusion that I should do a sudo modprobe sbs_battery After that there is a /sys/class/power_supply/BAT1 which would be nice if only its information was updated at all. But all info read from /sys/class/power_supply/BAT1/* will not change - it seems to get updated only once at boot time / first load of the module. uname -a: Linux notebook 3.19.0-031900-generic #201502091451 SMP Mon Feb 9 15:10:05 UTC 2015 i686 i686 i686 GNU/Linux ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: acpi bot-comment sbs vivid -- ACPI battery code broken with kernel 3.19 https://bugs.launchpad.net/bugs/1425316 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
