Hello guys, I bought a PowerBook 280c a while back. The guy I bought it from said it worked when he stored it 2 years ago, but it longer booted up. I got it for a pretty good deal along with a NIB power supply and a battery of unknown condition. I have not succeded in coaxing life out of this guy. I have tried it with a known good power supply, with and without batteries, I even removed the backup battery and did the PMU reset. No change. When I plug the AC adapter in, I hear the ticking of the working DC-DC circuit. By having the lid closed and pushing the button on the back, I noticed that sometimes the sleep light will blink 10 times in a row, kind of like a code. The most interesting thing was when I put it in my dock. The power supply of the dock made a high-pitched whining sound and nothing would respond; I had to manually eject the duo. We have removed the capacitors from the board, since they probably need replacing anyway. There was a small puddle underneath each cap! In removing the caps, some of the pads came with them. How can that be fixed? Any ideas on why the laptop wouldn't run? I have a 2300c that works fine with the dock and all the accessories. If anybody has a working 280c or even a good motherboard, I would be interested in a partial or full trade.
