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.

"The BlackBerry PlayBook tablet can now be charged even when fully powered down."

Is being turned on something that is a common need for tablets to be able to charge, or is this just every bit as fucked up as it looks at first glance?

When has this ever been an issue before?

Never heard of that before, but if it can be fixed by an update it means it's a software thing and not a hardware one.

So was it a bug or was is designed that it needed to be on to be recharged?

Either seems silly. During testing someone should have noticed it doesn't charge when powered down.

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.

From what I can glean, most devices need to be powered up to charge, strictly speaking, but if you plug them in while off, they power into some kind of intermediate charge-only mode automatically.
