Hello, I just tried out the new RC on my laptop system, initially neglecting to enable ACPI_PROCFS support. Thus I was thrust into using the new sysfs interface for the battery.c driver. .. Unfortunately the charge values etc do not seem to update periodically - only (un)plugging the AC power updates the status if ACPI_PROCFS is disabled. If ACPI_PROCFS is enabled then a read to /proc/acpi/battery/state gets the up-to-date data, and a subsequent read to the sysfs equivalents gives the same results - otherwise sysfs stays stale. If you need any more info please say so - this is on an ageing Toshiba Satellite 1110. Thanks, Ash - 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
