Not sure where to put this but I will try here: I have come across a troublesome LC575.
The machine will start up by pressing the power on button on the keyboard, and will boot normally to the desktop. However, that's not a lot of good, because it will not recognize the keyboard or mouse (cursor will not move, etc.) — apart from the power on button. The mouse and keyboard are known working.
Is this consistent with a blown ADB fuse or is there some other explanation? (N.B.: There are two "ADB" looking fuses on the logic board (silver, about 1/4" long).
