Won't Charge -- Fuse f5 blown & HOT Capacitors c52, c78, c92

Texto:

On this powerbook the fuse f5 near the power block blew. (area of the motherboard with the regulator, caps, resistors, etc near the connector to the wire going to the daughter-power-board)

On top of this the block of caps on top of the mobo near the power ribbon gets insanely hot.

The powerbook won't charge but will boot just fine, except fot the fact that this capacitor area gets insanely hot. (not normal compared to other powerbook boards)

I tried swapping out F5 but after a while it blows.

Anyone have the technicians manual with test points or know what sm components I should be looking to replace?

Thanks a bunch!
