On both my Toshiba laptops I can make profile settings that use way less CPU if I am going away for any length of time et leave it on to recieve mail. On the Aspire it seems I only have control over times the monitor, HD, standby and hibernate go into effect. I tried a download called SpeedSwitchXP. Everytime I try to install it I get a message that the wrong installer is present. I have never ... ever, gotten that message on any program I have downloaded. Now I'm searching again. Do you know anyway or any programs that gives control over the amount of CPU being used for the Aspire. Thanks! Jack
