charging iPhone with closed lid on mbp

I've been researching, but found nothing this specific so far. Related links:
- http://support.apple.com/kb/HT1476 - This says it may or may not charge
- http://forums.mactalk.com.au/11/72536-snow-leopard-not-charging-iphone-while-lid -closed.html - This says it should work since Leopard and if it's not working to reset the SMC should fix it (I haven't tried yet): http://support.apple.com/kb/HT3964
- http://forums.macrumors.com/showthread.php?t=795007 This is not the same model, but for him it seems to not work anyway
- http://discussions.apple.com/thread.jspa?threadID=2126178 Suggests http://support.apple.com/kb/HT3131 for dealing with closed lid, but requires external display, among other things that don't come to this case (or so I guess)

To me, experience showed that closing the lid with the iPhone already connected works fine. I'm using a macbook pro 2009, as already hinted elsewhere. It's 13'' if that makes any difference.

But if I have the computer sleeping in the bag and want to just plug the iPhone for charging convenience, then it doesn't work. I have to remove it, open the lid, wait for charging to begin, then I can safely close, sleep, put it back on the bag, and it will be charging.

So I wonder how this is supposed to work, and if I can "fix" this behavior. Anyone knows?

macbook pro 2009, Mac OS X (10.6.2), iPhone 3G OS 3.1.2 (upgraded as new device)

I actually solved it on my own luck. Oddly enough, just need to remove and re-plug.

Here, this is a small chart:

1- Computer with lid open, up and running with energy - whatever AC or not.
normal behavior, everything as expected: plug in iPhone it starts charging.

2- Computer with closed lid, sleeping as blinking light indicate and plugged in AC power.
normal behavior, everything as expected: plug in iPhone it starts charging.

3- Computer with closed lid for long time, unplugged from AC power, no cables on it whatsoever.
plug in iPhone - nothing happens.
unplug it and plug in again in either port - it starts charging!

If you close the lid and don't wait it gets to sleep (that is, white blinking light - if you want to be sure, wait till the computer cools down, if it was hot - that's sleep mode) you'll get normal behavior right on the first plug time. The trick of plugging again seem to work always from my tests. So this is a undocumented feature that took me freaking long enough to uncover!

Now it's aight! 😀
