Information processing apparatus with power shutoff switch and control method therefor for reducing power consumption in an image forming apparatus

An information processing apparatus includes a switching unit configured to be an ON-state in which power is supplied to the information processing apparatus and an OFF-state in which power is not supplied to the information processing apparatus, a driving unit configured to set the switching unit to the off-state, a voltage supply unit configured to apply a voltage to the driving unit, and a control unit configured to, in a case where a condition for shutting off the supply of power to the information processing apparatus is satisfied, perform control to apply the voltage from the voltage supply unit to the driving unit, and, after the voltage is applied to the driving unit, control the driving unit to set the switching unit to the off-state.
