I can confirm I still see this (or particularly do not see the state update after resume from sleep) on an Acer C720p in 16.04 as well; I had previously seen it in 15.10 on this machine but have seen it work on a modified 14.04 sometime ago.
The upower -d suggestion is not working for me (and running upower --monitor has no state changes when plugging/unplugging), nor is running gnome-power-statistics (it eventually fails with the following). Failure of gnome-power-statistics: (gnome-power-statistics:17074): libupower-glib-WARNING **: up_client_get_devices failed: Timeout was reached If I run upower -e to enumerate power sources I end up with a segmentation fault. I'll post the strace output as an attachment. -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-power in Ubuntu. https://bugs.launchpad.net/bugs/1008050 Title: After resume from suspend, power-indicator is unaware of battery changes Status in indicator-power: Incomplete Status in indicator-power package in Ubuntu: Incomplete Status in upower package in Ubuntu: New Bug description: When resuming from suspend, power-indicator seems to be frozen.
