Title:
  Power usage 50% worse than 14.04 on MacBook Air 6,2

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I do not know which package/condition to attribute this behaviour to,
  but MBA running Ubuntu 14.04 is using about 50% of power that needs to
  be delivered for 16.04. (minumum 10W power draw vs minimum ~5W draw).

  Otherwise 16.04 works well.

  Any clue how to tackle this?

  
  Best,
  b.
