It's dead Jim

[Redfraggle]

My Powerbook G4 has eaten its second adapter now. I'm not inclined to feed it a third. I'm curious to know if this has happened to anyone else though. Plus **sadness** (and yet happiness), I'm using a friend's old Dell laptop in the meantime. (sadness, windows; happiness internet access still)

The wire going from the brick to the PB first gets hot, and then hotter over time. It browns the cord (I've seen that happen, so have many people, and it was ok). Mine seems to take it a bit further, and then continue getting hotter and hotter. The PB itself gets quite a bit hotter, as does the brick. Eventually, it melts the cord just as the exit point from the brick (the thin one leading to the laptop), and then shorts in case I didn't notice. Thank goodness, I've not electrocuted myself nor caught anything on fire.

Thoughts?

Sagalore had a thought, but I'm going to save it and see what you all thought.

You might want to replace the DC-in board on your PowerBook.

That's the only thing I can think of.

DC In board is a good place to start. Every Apple laptop I have opened up manufactured after 1998 has had a separate DC In board, so although it will take a lot of work to get to it, once you reach it, replacing it should be easy.

Would a bad DC-in board cause the laptop to become excessively hot (even for this laptop) as it goes bad. I noticed that the laptop itself would run the fan more often and become extremely hot as it neared the point at which it would melt through the cord at the brick. The plug stayed cool (unlike the last one), but the brick became especially hot as well.

I am not too sure, but it can be a relatively inexpensive thing to replace. Certainly less expensive than replacing the whole logic board.
