QNX RIM has pushed the second update of the QNX-based operating system running on the PlayBook. One of the new features listed? "The BlackBerry PlayBook tablet can now be charged even when fully powered down." Oh my.

You mean that the device is not wired on the inside so that both have the action of a mechanical switch for turning the device on the "charging/on" state ? I had always thought, just sounded like the most clever option...

Well, at least the state is cleaned up. But I'd have thought that only the clock would remain powered on. Especially considering how much time most devices take between the moment where they are plugged in and the moment where they display some "charging..." indication.

It takes time to bring up the graphics stack that displays the charging indicator.

But what exactly is brought up when the device is in deep sleep then ? Is it only about keeping the minimal amount of electronic components on so that interrupts work, and wiring some interrupt handlers to the "load the rest of the OS" actions ?
