Notice that black bit on the PCB in the left-hand image? That's a chip, identified by the following text:
A3
2100
613A1
It most likely controls the switch between the orange "charging" LED indicator and the green "powered" LED. However, I wonder if this chip doesn't hold the answer to another mystery: why won't the Macbook battery charge off the Magsafe airline adapter?
For further information on the subject, I'd suggest Stuart Schmitt's guide to hacking the MagSafe cable for use w/ a standard DC transformer.

Hey Kieran, I had exactly the same problem. How did you solve it ?
I personnally soldered the thing back together, but this is just an fragile emergency fix :
- do you know where to find a replacement cord+plug ?
cheers from Paris,

My apologies for the delayed response.
My soldering held it together for a few weeks, but I wound up buying a new Magsafe tip on Ebay for around $15 -- much cheaper than a new transformer would have been.
Try searching ebay for "Kensington Smart Tip for Magsafe;" currently, there's one listed on ebay as item # 200242661468.
I replaced the wire w/ some proper copper wire I salvaged from an old power chord.
Hello,
I have most likely magsafe connector problem. Could you tell how non-destrutively go about disasembling the head of the connector? Thanks in advance
Zbigniewq,
I can't say there was any particular trick to prying it apart; it was mostly a matter of wedging a knife between the white plastic shell and the underlying metal. Go in from the business end of the plug.
That said, any fix you manage will probably be short-lived. I'd strongly suggest searching Ebay for "magsafe Kensington," and soldering on one of those $15 tips.
Just make sure you get the polarity right. There's a nice diagram here:

Hi. Just wondering if you know how might the white housing should come off the magsafe for me to repair to cord (broke off from fraying). I don't want to break it, someone mentioned it should slide off. Would a certain type of tool help so that I don't damage the housing?
Thanks from Portland Oregon,
Judy
Judy,
In order to get the white housing off, I slid a small knife blade between the housing and the underlying glue. (The assembly is protected and attached by something like glue-gun glue.)
I would recommend buying a replacement tip off ebay, however. Search for "Kensington Smart Tip for Magsafe." I found it impossible to re-solder the connection in a reliable fashion; it just broke and required more patching every couple of weeks.
