[Dell Latitude E6430] Only primary battery discharges with bay battery

[Laura Dietz]

When the machine is on AC power, we see that both batteries are charged,

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Speaking on behalf of Laura, I can confirm that the bug is still reproducible on 3.7.2. Note the extremely low energy-rate in BAT2.

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.
