Just for datapoint.. my T400, installed with RHEL6 october 31. (was
running fedora-13 before that, and RHEL5 before that), has only gone
trough 290 power cycles:

	  9 Power_On_Hours          0x0032   097   097   000    Old_age Always       -       12661

	 12 Power_Cycle_Count       0x0032   099   099   000    Old_age Always       -       290

management preferences (it's an SSD, so there's nothing spinning
