Fun Dell Mini 9 fact: You can stop the battery charging. I have no idea why anyone would want to do this, but this fun feature can be triggered unintentionally by utterly draining the battery. The feature can be toggled back using 'aircraft-manager-util AC_CHARGING on'. aircraft-manager-util can be obtained from http://dell-mini.archive.canonical.com/ubuntu/dists/hardy-dell-mini/universe/source/aircraft-manager_belmont11.tar.gz.

Why you would want to stop the adapter charging the battery is beyond me. Why the device would fail in such a way as to enable this state is a complete fucking mystery. And seriously, using inb and outb to play with direct port I/O in order to manage devices is just... so very wrong.

Thanks, Dell. Thell.
