Ok the patient here is a new 2.0 Ghz Macbook. I just woke it up- or tried to. the sleep light was on solid, not pulsing with as it does when sleeping. It didn't respond to key presses of track pad presses. It did power back on after pressing and holding the power key. The desktop was greyed out and a metered progress bar came up and it slowly booted bakc up then resumed as normal. Is this that deep sleep mode, or is this something else?
