I'm using ACPI 20050125 on a Dell Inspiron 300m (BIOS A07) with a 2.6.10 kernel, and a patched DSDT (http://acpi.sourceforge.net/dsdt/view.php? id=218). The battery's charge is being reported incorrectly--I at first thought my battery had gone bad until I accessed the battery level page in the BIOS setup, which reported the correct information. The battery is reported as completely dead (e.g. "remaining capacity" in /proc/acpi/battery/BAT1/state is 0 mAh) if the AC adapter is plugged in and 257 mAh as soon as I unplug the adapter. This is incorrect--the BIOS setup utility reports 100% charge. ACPI status reporting tools (like the GNOME battery status applet and the "acpi" command) reflect this in their percentanges. The battery's "info" entry: present: yes design capacity: 1799 mAh last full capacity: 1799 mAh battery technology: rechargeable design voltage: 14649 mV design capacity warning:180 mAh design capacity low: 54 mAh capacity granularity 1: 1 mAh capacity granularity 2: 1 mAh model number: serial number: battery type: LION OEM info: DELL Computer Corporation Windows was on this laptop for a few months before I installed Linux, could that have anything to do with it? I'm afraid I don't know enough about how ACPI works to know if that's a factor or not. As far as I know, this is a new problem because most of the ACPI quirks had gone with the previous ACPI release I had used (not sure exactly of the version: probably 20041202).
