Macbook battery charger heat .. HOT !!!
I also have a Nov 2006 madeMacbook 1.83 Intel Core 2 Duo. My charger is also too hot to touch. I well have to order a spare, even after replacing this one. I did speak with Apple care today annd here is the story.
After the technician, if you could call them that, verified my problem several, several, several times, and then putting me on hold for another 10 minutes or so, they said they would replace it and asked for my credit card. I said, what ?????? yes, they bill you for the charger until you return the old / broken part.
These charger problems are not new as I had a problem immediately with my old G3 iBook 700. They replaced that charger very quickly and never even asked me to return the broken one.
Apple / Mac is really changing for the worse. Mainly support , well, support and product quality control ! A long time Mac user, digital audio and always rock solid until my last 3 Mac , G4 867 dual, G3 Ibook 700, and G4 1.25 dual.
All had problems $800 repair on my G4 1.25 dual that didn't work upon return , so they tried to fix it again .. it never worked properly after that, a G3 700 iBook that never worked out of the box.
Now, my Macbook works better than any of the previous .. however, I do not ecpect it to last. Apple Care is a must (what a scam) and a spare charger is a must. They really got us where they want us.
Anyway, your charger is covered.
good luck
