Comment 7 for bug 1008050

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.
