It's a completely different power management scheme. Just like in the Matrix when the kid says 'there is no spoon' under the new Intel Power Management scheme 'there is no sleep'I have exactly the same problem.
Every time I leave the office or home or go to bed, I thought I was putting the SP3 to sleep by pressing the on/off button or putting the keyboard case on.
More of a problem when I am on the road in my motorhome and need to conserve power. Overnight it can run down to almost nothing.
In simple terms how do we put the SP3 to sleep - no jargon now! Or are you all saying that shutting down Chrome will solve the problem?
