Hello,

is there a possibility to get a circuit scheme for a Powerbook G4, 1.67GHz?
A small piece on the motherboard started to smoke. We have the possibility to
replace it, the problem is, that it cannot be recognized. The piece in question
is labeled "3BDBK", the spot on the board "Q1585". Any ideas what this thing
is?

Regards,
Christoph Gartmann

Probably the easiest thing is to look for a similar broken PowerBook or
logic board on eBay and then either swap the part or the logic board as
appropriate.
