Red Hat Bugzilla – Bug 218440
Changes during hibernate not detected
Last modified: 2013-03-05 22:48:25 EST
Description of problem: If I hibernate my laptop with mains connected, then disconnect the mains supply and de-hibernate it GNOME Power Manager shows the computer as using AC power (i.e. mains plug icon and tooltip). Version-Release number of selected component (if applicable): 2.17.2.1 How reproducible: Consistent Steps to Reproduce: 1. Start Fedora on laptop with mains connected, Power Manager shows mains socket icon, tooltip says "Computer is running on AC power". 2. Select System->Shut Down... and select Hibernate when prompted. Computer hibernates. 3. Disconnect mains supply. 4. Start Fedora resuming from hibernated state. Actual results: Power Manager still shows mains socket icon, tooltip says "Computer is running on AC power". Expected results: Power Manager shows battery icon and associated tooltip.
When you've done that, and you resume on battery, what does "lshal| grep battery" say?
It says: battery.charge_level.percentage = 100 (0x64) (int) battery.charge_level.rate = 0 (0x0) (int) battery.charge_level.last_full = 61257 (0xef49) (int) battery.charge_level.current = 61257 (0xef49) (int) battery.voltage.current = 11330 (0x2c42) (int) battery.reporting.rate = 0 (0x0) (int) battery.reporting.current = 61257 (0xef49) (int) battery.charge_level.capacity_state = 'ok' (string) battery.rechargeable.is_discharging = false (bool) battery.rechargeable.is_charging = false (bool) battery.is_rechargeable = true (bool) battery.alarm.unit = 'mWh' (string) battery.alarm.design = 1231 (0x4cf) (int) battery.charge_level.unit = 'mWh' (string) battery.charge_level.granularity_2 = 10 (0xa) (int) battery.charge_level.granularity_1 = 10 (0xa) (int) battery.charge_level.low = 0 (0x0) (int) battery.charge_level.warning = 1231 (0x4cf) (int) battery.charge_level.design = 71280 (0x11670) (int) battery.voltage.design = 10800 (0x2a30) (int) battery.voltage.unit = 'mV' (string) battery.reporting.granularity_2 = 10 (0xa) (int) battery.reporting.granularity_1 = 10 (0xa) (int) battery.reporting.low = 0 (0x0) (int) battery.reporting.warning = 1231 (0x4cf) (int) battery.reporting.design = 71280 (0x11670) (int) battery.reporting.last_full = 61257 (0xef49) (int) battery.reporting.unit = 'mWh' (string) battery.technology = 'lithium-ion' (string) battery.reporting.technology = 'Li-ION' (string) battery.serial = '0000001815' (string) battery.model = 'G71C0001Q210' (string) battery.present = true (bool) info.capabilities = {'battery'} (string list) info.category = 'battery' (string) battery.type = 'primary' (string) linux.acpi_path = '/proc/acpi/battery/BAT1' (string) battery.present = false (bool) info.capabilities = {'battery'} (string list) info.category = 'battery' (string) battery.type = 'primary' (string) linux.acpi_path = '/proc/acpi/battery/BAT2' (string)
It says: battery.rechargeable.is_discharging = false (bool) battery.rechargeable.is_charging = false (bool) So your battery doesn't think it's discharging. I think theres a kernel patch in the process of getting upstream that will help here, as it forces a battery refresh on un-freeze. That should help. I'll try to find out what kernel it is in, if that is it's already in vanilla.
Yes, this kernel patch is now upstream. Can you test with a fairly recent rawhide or F7 snapshot and see if the problem is fixed please? Thanks.
The information we've requested above is required in order to review this problem report further and diagnose/fix the issue if it is still present. Since there have not been any updates to the report since thirty (30) days or more since we requested additional information, we're assuming the problem is either no longer present in the current Fedora release, or that there is no longer any interest in tracking the problem. Setting status to "INSUFFICIENT_DATA". If you still experience this problem after updating to our latest Fedora release and can provide the information previously requested, please feel free to reopen the bug report. Thank you in advance.
