Title:
  unreasonably high power consumption in precise

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  What happens:
  Under Ubuntu 12.04, the system's power consumption is around 32 Watts idle, which is unbelievably high compared to the 12 Watts consumed by Ubuntu 10.04. I believe this could be a kernel problem.

  What should happen:
  The system's total consumption should be around 12 Watts.

  Software:
  - Ubuntu 12.04 LTS
  - fresh install

  Kernels I've tested are all affected:
  - 3.1.5
  - 3.2.0
  - 3.2.5
  - 3.3.3
  - 3.3.4
  - 3.4.0-rc4

  Hardware:
  - HP nc6320
  - Intel Core Duo T2300
  - Intel Graphics 945GM
