Macintosh Quadra 605 Issues

PRAM Battery leaks

The 1/2AA Lithium barrel battery used for keeping track of PRAM settings on the logic board is prone to leaking. Several brands were used, but all will leak with age. These leaks can be absolutely catastrophic, with extremely severe corrosion being common. In most of these cases, the board is unrecoverable. So, remove those batteries!


Leaky Caps

Just like the LC475, the Quadra 605 has an assortment of leaky capacitors on its logic board that always need to be replaced. You can find capacitor reference for this model over at the resources page.


Power Supply Failure

Pizza box LC/Quadra Power Supplies are failing rampantly due to bad capacitors. You can either recap the original PSU or replace it with a modern alternative.
