still haven't found the issue with the one ibook g4 i have that does work _sometimes_...
board flex in a certain place seems to make it boot, near where the battery is, but i can't find any broken solder there
one of the two USB ports accuses power issues and won't enumerate...
... and plugging an ethernet cable in causes everything to hang within a few seconds
it's a truly cursed machine for how much it still seems to work sometimes
