I just stripped down a powerbook duo 270c which has a busted screen.

I have noticed that the few electrolytic SMD caps this board has, are starting to leak, leave signs.

The large 100uf capacitors in the voltage regulator DC-DC circuits are the ones I am talking about. This is dangerous. Blow your DC-DC circuits, and its Game Over... Permanently....

Granted most of them are tantalum capacitors, There are still 7 aluminum electrolytics, 6 of those being in the Heart. Board has a heart-attack, it dies.... xx(

TIME TO RECAP
