In a resonating circuit, at different frequencies you have different values of current for a constant value of voltage. And hence different amounts of power. Hence the point at which the power is maximum for a series RLC circut is the maximum power point.
Half power points correspond to those frequency points where the max power falls to half value of max power. There the current falls to 0.707 of its max power value.
