Laura Dietz, as per http://www.dell.com/support/troubleshooting/us/en/19/Product/latitude-e6430 an update is available for your BIOS (A12). If you update to this, does it change anything?
If not, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Thank you for your understanding. ** Tags added: bios-outdated-a12 needs-upstream-testing regression- potential ** Tags removed: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Only primary battery discharges on Dell Latitude E6430 with bay battery + [Dell Latitude E6430] Only primary battery discharges with bay battery -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1077952 Title: [Dell Latitude E6430] Only primary battery discharges with bay battery Status in “linux” package in Ubuntu: Incomplete Bug description: When the machine is on AC power, we see that both batteries are charged, $ upower --dump Device: /org/freedesktop/UPower/devices/line_power_AC native-path: /sys/devices/LNXSYSTM:00/device:00/ACPI0003:00/power_supply/AC power supply: yes updated: Mon Nov 12 09:02:34 2012 (261 seconds ago) has history: no has statistics: no line-power online: yes Device: /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0 vendor: Sanyo model: DELL NH6K925 serial: 630 power supply: yes updated: Mon Nov 12 09:06:39 2012 (16 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 32.7672 Wh energy-empty: 0 Wh energy-full: 60.1953 Wh energy-full-design: 62.16 Wh energy-rate: 29.7813 W voltage: 11.546 V time to full: 55.2 minutes percentage: 54.4348% capacity: 96.8393% technology: lithium-ion History (charge): 1352729199 54.435 charging 1352729169 54.029 charging 1352729139 53.623 charging 1352729109 53.199 charging History (rate): 1352729109 29.781 charging Device: /org/freedesktop/UPower/devices/battery_BAT2 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:02/power_supply/BAT2 vendor: Samsung SDI model: DELL W1GGM25 serial: 36939 power supply: yes updated: Mon Nov 12 09:06:39 2012 (16 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: fully-charged energy: 27.6723 Wh energy-empty: 0 Wh energy-full: 30.0033 Wh energy-full-design: 31.08 Wh energy-rate: 0.0111 W voltage: 12.4 V percentage: 92.2309% capacity: 96.5357% technology: lithium-ion Daemon: daemon-version: 0.9.17 can-suspend: yes can-hibernate no on-battery: no on-low-battery: no lid-is-closed: no lid-is-present: yes is-docked: no When the machine is unplugged only the primary battery discharges, $ upower --dump Device: /org/freedesktop/UPower/devices/line_power_AC native-path: /sys/devices/LNXSYSTM:00/device:00/ACPI0003:00/power_supply/AC power supply: yes updated: Mon Nov 12 09:08:20 2012 (2 seconds ago) has history: no has statistics: no line-power online: no Device: /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:00/power_supply/BAT0 vendor: Sanyo model: DELL NH6K925 serial: 630 power supply: yes updated: Mon Nov 12 09:08:20 2012 (2 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: discharging energy: 33.5775 Wh energy-empty: 0 Wh energy-full: 60.1953 Wh energy-full-design: 62.16 Wh energy-rate: 9.6903 W voltage: 11.294 V time to empty: 3.5 hours percentage: 55.7809% capacity: 96.8393% technology: lithium-ion History (charge): 1352729299 55.781 discharging 1352729289 55.670 charging 1352729259 55.246 charging 1352729229 54.840 charging 1352729199 54.435 charging History (rate): 1352729300 9.690 discharging 1352729299 10.279 discharging Device: /org/freedesktop/UPower/devices/battery_BAT2 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0C0A:02/power_supply/BAT2 vendor: Samsung SDI model: DELL W1GGM25 serial: 36939 power supply: yes updated: Mon Nov 12 09:08:20 2012 (2 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: discharging energy: 27.6723 Wh energy-empty: 0 Wh energy-full: 30.0033 Wh energy-full-design: 31.08 Wh energy-rate: 0.0111 W voltage: 12.4 V percentage: 92.2309% capacity: 96.5357% technology: lithium-ion Daemon: daemon-version: 0.9.17 can-suspend: yes can-hibernate no on-battery: yes on-low-battery: no lid-is-closed: no lid-is-present: yes is-docked: no Once the primary battery is empty, the machine suddenly shuts off.
