I will find a sandybridge machine to test it after back to Taipei office. That
will be better use 2-channel power metter or even NetDAQ to measurement the
Watt value.

6 Watt is a huge power leak, we should check the machine on idle status, first.

Richard and Andrew, could you please you powertop to check the CPU go to
When the machine is idle, the CPU state most of the time in C4 state.
