Not necessarily. Are you sure the power adapter you purchased works with the 180c? Even though the plug fits and they look physically identical, the power adapters for the black and white Powerbook 1xx series didn't have enough oomph to power the color models. Looking at the specs, the 180c needs a 24W adapter. Check the back of your adapter - is that what you have?Do I consider it fried?
I'll pull it apart tomorrow and take pictures. It had been in the garage for awhile, but was working when I last tested it afterwards. The battery however had bloated up and came apart. Doesn't seem to have done any damage in the slot, but could be somewhere else. All I know is that it gets hot in the back and it smells a bit like plastic (but my iPhone smells like that too, go figure .).Hmmm...sorry - I'm all out of ideas beyond pulling it apart and removing the memory module and HDD.
