<P> A CPU chip is designed for portable computers , it is typically housed in a smaller chip package , but more importantly , in order to run cooler , it uses lower voltages than its desktop counterpart and has more sleep mode capability . A mobile processor can be throttled down to different power levels or sections of the chip can be turned off entirely when not in use . Further , the clock frequency may be stepped down under low processor loads . This stepping down conserves power and prolongs battery life . </P>
