On 2.6.24 kernels with ACPI_PROCFS_POWER and ACPI_SYSFS_POWER enabled, sys-apps/hal reports two batteries, one from sysfs and one from procfs. This is on a system with one physical battery. This breaks battery functionality on laptops for battery management daemons (like kpowersave) cannot accurately calculate remaining battery life and discharge rate. The linked blog post from Danny Kukawka talks of patches that fix this behavior. This happens on sys-apps/hal-0.5.10 and lower. Reproducible: Always Steps to Reproduce: 1. Configure a 2.6.24 kernel with ACPI_PROCFS_POWER and ACPI_SYSFS_POWER enabled 2. Install sys-apps/hal 3. Install sys-power/kpowersave or similar battery life utility that relies on hal for information (>=sys-apps/kpowersave-0.7.3 no longer rely on powersaved) Actual Results: kpowersave will report two batteries, one that dischages with system usage and one that remains at full power with 0.00 hours remaining. Expected Results: kpowersave should report the correct number of physical batteries as well as the correct power consumption and battery life remaining.

Created attachment 147196 [details, diff] Backported fixes for non-updating battery when CONFIG_SYSFS_POWER is enabled. Here's a patch that contains the official fixes for this issue against 0.5.10. Works For Me (TM) ;-)

I had already applied such a patch myself I was just hoping that the ebuild devs would add it to the official ebuild. The "official" solution is to disable the offending /proc iterfaces.

Yah, I also tried turning off the deprecated /proc interfaces, which of course fixes the duplicate battery problem, but I still end up with HAL not sending update events for the charge level, as described in the OP. So my battery indications stay stuck at 99%. The patch fixes both problems. Cheers!
