The Dell Latitude E6410 I've got here hibernates upon resume if no AC adapter is plugged in, with Oneiric. Apparently the kernel adds a second battery into sysfs only after resume that's not actually present but which is interpreted as being a battery with 0% charge. The power symbol in the panel is also telling me that a battery is missing.
I guess the slot is the one of the DVD disk drive, where you could plug in a second one. On boot I get this:
[ 2.352062] ACPI: Battery Slot [BAT1] (battery absent)
If you read the /proc/acpi/battery/BAT1/* entries, the kernel drops the battery from sysfs again and the icon returns to the right battery BAT0. Sadly the whole problem is critical as hibernation does not seem to work with Oneiric and this particular type of laptop. So there's certainly a kernel bug involved, but gpm also doesn't seem to handle the situation gracefully.
The uname output is as follows: Linux roadrunner 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux
The package versions in question are linux-image-3.0.0-12-generic 3.0.0-12.20, gnome-power-manager 3.2.0-0ubuntu1 and upower 0.9.13-1. (upower emits signals for both batteries in question and continues to poll the absent BAT1 every second.)
There's a bug report over at RedHat which contains a workaround that touches those files post-resume. I did not test it yet and it's clearly a hack because the kernel shouldn't add it in the first place.
