Just curious, i plugged my old 2007 magsafe into my new 2012 15" and the notebook sees it but says "not charging"

The Mid-2012 15" retina and non-retina need a 85 watts power adapter. See also:

derp, now the old charger charges it..lol guess i didnt have it plugged in all the way or something
 
On my new 2012 Macbook Air with Magsafe 2, the magsafe 2 to magsafe 1 adapter seems to either charge or power but not at the same time. If the macbook air is on, I get a "not charging" error, but it is powered by ac power. If I power the macbook down, it will charge.

Intended behavior or bad adapter?

Interesting. I hope that is NOT the intended behavior. I purchased a couple of the adapters for my extra 85W L shaped plugs and i will be extremely disappointed if that is the case.
 
I'm using the magsafe that came with my 2010 MBP on my new 2012 MBP. Only the Air and rMBP have the new Magsafe 2. With the adapter, you can still use the old ones.

I have a genius bar appointment in 1.5 hours. I'll try to post back the results.
 
The converter I had was defective, and they swapped it for a new one that works fine -- powers and charges at the same time. The apple care tech who told me otherwise wasn't too sharp, apparently.
