Why would the dc-in get very hot and melt a solder joint
The dc-in got very hot and stop working. I pulled the plug out of the laptop right away. But the laptop kept running on the battery no problem. I then shut it off right away then later on. I pulled it all apart and found out that. On the dc-in sound board. Where the dc-in is attached to the board. One of the solder joints was melted. Also one of the first things i check was. The dc plug with my ohm volt meter its find. Plus i have two Powerbooks both the same model A1095. The dc plug been working fine for my second powerbook for over two weeks. The only thing that has been done to this laptop. Was the hard drive went bad and replaced it. With a used hard drive but with a up dated OS x 10.4.11 to OS X 10.5.8 As to the hard drive before it went it bad. It made the normal clicking sounds of a hard drive going bad.
Is this a good question?
Tell us a bit more about this new AC adapter you bought. Also, like fryarludwig already pointed out, post some images and lets see the damage.
