I thought with the physical layout of the motherboard, CPU towards the
outside of the screen lid, that e-book mode would be the hardest on the
XO in terms of heat dissipation. Given there in no active cooling, is
the heat spreader test not measuring the difference in temperature
between the 2 modes of operation?
