hot power adaptor (square white ones) for TiBook

[Selwyn Ward]

I too have had one of these go (actually for the 17" Al not the Ti). I guess
it's probably an internal fuse, tho' it smelt of charred plastic, but there
doesn't seem to be an obvious way of repairing the unit.  I was within
warranty so I phoned apple and they sent a replacement (tho' it took a while
as they first sent me power supply for a cinema display, which I don't
have).
