Usually the screen saver is suspended when display power saving kicks in, as nothing can be seen on the screen anyway, obviously. However, some screen savers actually perform useful computations, so it is not desirable to suspend them.
Polo xeral o protector suspéndese cando o aforro de enerxía da pantalla entra en acción, xa que non se poderá ver nada na pantalla. Porén algúns protectores fan cálculos de utilidade, polo que non é desexábel suspendelos.
