I have a powerbook 540c which was sleeping for several years with the power hooked up. I just found that it has dead batteries(about 3v) and the power supply has red and blue leads with 16.4v and orange and black leads with 2.1v. The specs call for two 16.6v sources of power. I think there is a power supply problem which caused the problem, but it seems that either the batteries should be dead or the computer unable to run without batteries. Is it possible that the computer is ok once proper power is supplied? I opened the power supply box and it is complicated, so I don't know where to start to trouble shoot it. Before trying to fix it or replace it I would like to find a way to get power to the unit to verify it is still good. Where do I go now. 8-o
