Hey,
Using hot glue to fix that little chip on iBook G4 isn't what I'd do - it'll just fail again within time and be a right royal bugger to remove (and you'll probably rip off the little chip getting the glue off). I was recently given the same specced iBook G4 1.07 - in pieces - same issue with the little chip (someone had already tried to fix it with a heap of BlockBuster video cards - layer upon layer as it got worse!), and just touched each leg for ~ 3 seconds @ 350 - 400deg C. This was using a not-very-fine-tipped iron point and wasn't at all hard to do, and it's been fine ever since.

Unless you can solder it back, glue/shim/clamps will work for a while but can never be considered 100% reliable in the long term.

I have to admit... agreed. I'd never just apply the glue straight on. After reflowing the legs of the chip, all I did was to apply the glue to a known dead iBook logic board to form the basis for the "mould". Once set over that, I removed it from the dead board and carefully lay it in position on the good iBook board- this gives it the extra bracing needed to support the chip whether it's reflowed or not (although applying it after the reflow will somewhat help prevent it cracking from heat again).

Was surprised I didn't rip the chip from the board when removing it from the scrap board actually... they hold down tougher than I thought. I fixed that old board too, but I want to see how long it lasts without being reflowed first. That one is my "test iBook".
