    My question is: for t>0, Should I treat the depentent 4io source as zero since the current io indicated on the figure is zero ?

    Any help is appreicated.

    I think so. That would nullify the current source and leave only the middle voltage source to power the circuit after the switch is flipped.

    Yes, make sure you replace it by a short, because its going to effectively short out the rightmost portion of your circuit.

    Jegues has corrected me. I mistook the dependant source for a current one, while it is a voltage source. Shorting it is mandatory.
