or the system hangs when the battery charge reaches less than one percent.

Does this mean my system won't shut off when the battery dies anymore? That's always bugged me when that happens...

These firmware updates happen super fast on a SSD based Air.

I think its because the update is like 250 kilobytes in size not because of the ssd
