A couple days ago, I updated my test build to commit 8033c6e9736c29cce5f0d0abbca9a44dffb20c39 and noticed an odd behavior with the battery. If I unplug the power, the battery discharges and that is reflected in /proc/acpi/battery/BAT0/state. I am not certain the discharge is continuous and uniform or if it goes in steps. When I plug the power back in, the level stays at a constant value (+-1mAh) for a considerable period of time. It then does a single step back to the fully charged value. I have not done any searching to see when this began. I had been running the ubuntu 2.6.22-14 kernel before this and the behavior was normal. I am not certain what information you will need. Commit is above. $ cat /proc/acpi/battery/BAT0/alarm alarm: unsupported $ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 4800 mAh last full capacity: 4096 mAh battery technology: non-rechargeable design voltage: 12588 mV design capacity warning: 1000 mAh design capacity low: 400 mAh capacity granularity 1: 100 mAh capacity granularity 2: 100 mAh model number: serial number: battery type: LiOn OEM info: Sony Corp. $ cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charging present rate: unknown remaining capacity: 4096 mAh present voltage: unknown What I think is relevant .config information: CONFIG_ACPI=y CONFIG_ACPI_SLEEP=y CONFIG_ACPI_PROCFS=y CONFIG_ACPI_PROCFS_POWER=y CONFIG_ACPI_SYSFS_POWER=y CONFIG_ACPI_PROC_EVENT=y CONFIG_ACPI_AC=m CONFIG_ACPI_BATTERY=m CONFIG_ACPI_BUTTON=m CONFIG_ACPI_VIDEO=m CONFIG_ACPI_FAN=m CONFIG_ACPI_DOCK=m CONFIG_ACPI_BAY=m CONFIG_ACPI_PROCESSOR=m CONFIG_ACPI_HOTPLUG_CPU=y CONFIG_ACPI_THERMAL=m CONFIG_ACPI_WMI=m CONFIG_ACPI_ASUS=m CONFIG_ACPI_TOSHIBA=m # CONFIG_ACPI_CUSTOM_DSDT is not set CONFIG_ACPI_BLACKLIST_YEAR=2000 # CONFIG_ACPI_DEBUG is not set CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_SYSTEM=y CONFIG_ACPI_CONTAINER=m CONFIG_ACPI_SBS=m CONFIG_X86_ACPI_CPUFREQ=m CONFIG_X86_POWERNOW_K7_ACPI=y CONFIG_X86_POWERNOW_K8_ACPI=y # CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set CONFIG_HOTPLUG_PCI_ACPI=m CONFIG_HOTPLUG_PCI_ACPI_IBM=m CONFIG_PNPACPI=y CONFIG_THINKPAD_ACPI=m # CONFIG_THINKPAD_ACPI_DEBUG is not set CONFIG_THINKPAD_ACPI_BAY=y CONFIG_THINKPAD_ACPI_VIDEO=y CONFIG_THINKPAD_ACPI_HOTKEY_POLL=y CONFIG_BLK_DEV_IDEACPI=y CONFIG_ATA_ACPI=y CONFIG_PATA_ACPI=m CONFIG_SONY_LAPTOP=m CONFIG_SONYPI_COMPAT=y CONFIG_SONYPI=m Thanks, Robin Holt -- 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
