In netbooks with intel atom processor and nvidia ion graphics it used Optimus technology to save battery life. Do sandy bridge desktop/notebook processors do this as well ?

Im sure SB gpu is always disabled when a discreet gpu is found on the system but most new Nvidia/AMD gpus are quite good on power in idle anyway.
