You can still give us numbers without resuming and just using clock
scaling can C-states. That would be a far more realistic battery life
number to shout out to the world, than what happenned with the XO-1.
If the laptop can only handle 3 hours without suspend that's fine,
it's a baseline. If it could do 5 hours than it would be great.

Best regards,
