Red Hat Bugzilla – Bug 462165
Batteries are not managed properly

Description of problem:
I have Compaq6715b laptop with two batteris - standard one and external one. After upgrading kernel system apps (kpowersave and gnome-power-manager) and showing that I have 4 batteries installed. Battery 2 is external battery (checked by removing it) and I guess battery 4 is standard one. Battery 1 and 3 are showing constant 98% charge level. Total level of charging and remaining time while working on batteries have nothing in common with real situation.
Here are some ACPI logs from dmesg:
ACPI: AC Adapter [C1EB] (off-line)
ACPI: Battery Slot [C1ED] (battery present)
ACPI: Battery Slot [C1EC] (battery present)
Version-Release number of selected component (if applicable):
This problem had been in early 2.6.25 kernels from Fedora packages, but has been solved. In kernel kernel-184.108.40.206-69.fc8.x86_64.rpm I had been using lately everything had been working properly. Now same problem occurs again. I am using latest kernel-220.127.116.11-14.fc8
Boot latest kernel on Comapaq 6715b laptop
System apps displays 4 batteries and charge level and remaining time have nothing in common with real situation
Two batteries visible on system and proper charging level and display time returned.
Seems to be fixed in kernel 18.104.22.168-28.fc8
