Hi, I have an issue with my Arch installation on an X220 laptop. Linux jamie-laptop 3.1.5-1-ARCH #1 SMP PREEMPT Sat Dec 10 14:43:09 CET 2011 x86_64 Intel(R) Core(TM) i5-2410M CPU @ 2.30GHz GenuineIntel GNU/Linux If I boot with AC plugged in the /sys/class/power_supply/BAT0/ directory is populated with charge_*, but if I boot on battery the directory is populated with energy_*. Disconnecting/connecting the power after boot does not effect the file names. Is this a bug or a feature? It makes scripts harder to write than necessary. Thanks, Jamie ps, I really think http://www.lesswatts.org/projects/acpi/mailing-lists.php needs updating. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
