UPower expects the the kernel to produce uevents for battery and ac adapter status updates but it won't do it on this device. While UPower forces an update for the battery every 30 seconds (UPowerd tells me: 'No updates on supply /org/freedesktop/UPower/devices/battery_BAT1 for 30 seconds; forcing update') it doesn't force an update for the ac adapter.
This seems to be the reason why the charging level reported by the GNOME battery status applet corresponds to the reported value in /sys/class/power_supply/BAT1/uevent (POWER_SUPPLY_CAPACITY) but at the same time the notebook will not be sent into hibernation when battery status is critical – UPower thinks the notebook is still on ac power. Since I don't see any power related uevents with 'udevadm monitor' I guess this is a kernel bug. -- 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/994745 Title: Power indicator fails to recognise unplug Status in The Linux Kernel: Unknown Status in Upower: Confirmed Status in “linux” package in Ubuntu: New Status in “upower” package in Ubuntu: Confirmed Status in “linux” package in Debian: Confirmed Bug description: Upon unplugging the power on HP Folio 13 running Precise the power indicator fails to recognise the unplug. The charging laptop symbol remains. Power-statistics also becomes unresponsive/empty of data. Powertop recognises the unplug, but Jupiter which I have installed does not. If I suspend and resume or restart, the fact that I am on battery power is once again recognised.
