While discuss the Alarm Clock feature with a customer, an interesting question was raised. "What if the system is in Sleep mode and in the user's bag? Will the Alarm Clock still work and wake the system?"
The quick answer: No - Alarm Clock will not wake the system if in Sleep mode and on battery (i.e. DC) power. The system must be on AC power (i.e. power cord attached)
The reason is provided below with brief explanation. The two windows shown were actually captured at different times.
Here is a brief explanation of the select power policy:
Hopefully the above explanation will answer that lingering question - "Could Intel AMT power-on my system when I'm boarding my next flight?". Nope - Intel AMT won't. But if you forget to power down your laptop before take-off, you'll simply have a little less battery power during your flight and the stewardess might be upset before you reach 10,000 feet
