Quadra 650 | Common Issues |
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!
The Quadra 650 doesn't have any electrolytic caps on the logic board, but there are plenty in the power supply that can also fail. Recapping a Q650 will usually bring a dead one back, but there are exceptions where a full replacement may be required.
