dc in board, possibly blown?
I've been trying to figure out why I can't get my ibook g4 to turn on.
I opened it up to see if there was a problem with the dc in board and this is what I found:
The end nearest to where the adapter plugs in has two small pins next to each other and one of them looks burnt. The one beside it is silver, shiny and looks fine. The one in question is black and a little powdery around it.
I opened the laptop on a whim, I didn't really know what I was looking for.
I bought a new adapter, and it helped for a little while.
I bought a new battery, and it also helped for a little while but it stopped charging after five months of use.
It started shutting off while in use. So I tried resetting the PMU with no results.
When I push the power button, it makes a sound that's hard to describe. It's a grinding whir, I suppose. Sometimes it's really slow and will keep going for a while. Sometimes it's quicker then just stops.
Any advice is greatly appreciated. :)
