Hi,
An Ivy Bridge based laptop (or Ultrabook) can have a system idle power consumption as low as 5 W (not counting the display power consumption). However a corresponding desktop Ivy Bridge system will have a system idle power consumption of around 30 W.
So how come there's such a huge difference in idle power consumption, even if both computer have about the same hardware (SSD, RAM, and only use IGP)?
Does anyone have a clue where the extra 25 W are wasted on the desktop computer?
