This depends a lot on the hardware, OS, client, and power consumption settings. It is possible to run one of these programs without significantly altering the power consumption of the machine. The laptop I run SC and fold...@home on cruises along at 800Mhz most of the time. It instantly scales up to 2.2Ghz (or any of the notches in between) if a process with a high priority demands it. -- cooppw02 ------------------------------------------------------------------------ cooppw02's Profile: http://forums.slimdevices.com/member.php?userid=16712 View this thread: http://forums.slimdevices.com/showthread.php?t=63681 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
