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.

I can see how this got through the testing phase myself.

Many devices nowadays are designed to be permanently sleeping to various degrees, and rarely, if even, be fully powered down. So it's logical that they did not experiment a lot with this operating mode during the testing phase, which focuses on the target use cases of the manufacturer.

30 second boot times are too much and fixing it would require too much effort, I guess... So let's waste power and never clean up the device's state instead.

Actually, "turning the device off" often reboots the device, to a state where you got the kernel running in an "acting dead" state, where charging (and detecting when power button is pressed to "turn the device on") can occur.

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.
