3rd Gen X1 Carbon; type 20BT Does the battery charge with the machine powered off? Good question; I haven't tested that. Presumably yes, but I'll verify later after work and get back to you. (This is my sole work machine I'm afraid). FWIW, normal battery functionality exists when I'm running the previous kernel, in my case 4.1.8-200.fc22 I can confirm battery functions normally and charges when the laptop is powered off; also when running kernel 4.1.8-200.fc22. The behavior only exhibits when running 4.2.3-200.fc22. Please let me know what you need me to gather to help diagnose this; I'm happy to provide stuff! :-) Can you attach the contents of /sys/class/power_supply/BAT*/uevent for me please? Hey Justin, I rebooted into the 4.2.3 kernel on full charge. [dpeacock@frodo ~]$ cat /sys/class/power_supply/BAT0/uevent POWER_SUPPLY_NAME=BAT0 POWER_SUPPLY_STATUS=Discharging POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-poly POWER_SUPPLY_CYCLE_COUNT=0 POWER_SUPPLY_VOLTAGE_MIN_DESIGN=15200000 POWER_SUPPLY_VOLTAGE_NOW=17159000 POWER_SUPPLY_POWER_NOW=5731000 POWER_SUPPLY_ENERGY_FULL_DESIGN=50220000 POWER_SUPPLY_ENERGY_FULL=47800000 POWER_SUPPLY_ENERGY_NOW=47510000 POWER_SUPPLY_CAPACITY=99 POWER_SUPPLY_CAPACITY_LEVEL=Normal POWER_SUPPLY_MODEL_NAME=00HW002 POWER_SUPPLY_MANUFACTURER=LGC POWER_SUPPLY_SERIAL_NUMBER= 703 Inexplicably, after a bunch of rebooting to test this, and no config changes, battery function appears to be working fine again! Argh! I don't know if this is an intermittent bug or if something was out of whack immediately after the update, but I'll let you know if it occurs again. How frustrating! Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
