II have 13' 360 Pro with i5, what i could do is to remove most of the extra software loaded, specially Samsung find and file tracker. Both takes good power when you press alt + ctr + del and choose detailed task manager (short by power -last column), Quick search must be indexing the data which is high recourse consumption.
IT did my books overheating problem to a large extend .
below is the screen shot of the Samsung update app and you see i have removed many (need not to have Samsung do the same work what windows can handle)
wish this helps!
