Sleep Spent

My iBook sends current to connected FireWire devices when it’s on, or when it’s asleep and plugged in. When it’s asleep and running on battery power, though, it doesn’t power the FW port.

This is the way it should be. This is great! No worries about killing the battery after leaving an iPod plugged in all night.

I was mentioning this to a friend who worked on the iBook a few years ago, and he said he actually had a hand in implementing this very feature differently on the 12-inch PowerBooks last year. I thought that was pretty neat. :-)
