Title:
  power regression + fan noise with with kernel 3.0.0-x

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I have a power regression + over heating with my dell 7110c laptop
  I have tried the following fixes :
  pcie_aspm=force
  i915.i915_enable_rc6=1
  i915.i915_enable_fbc=1
  i915.lvds_downclock=1

  Much better results (the fan finally stop turning at lest for a while)
  but it is not comparable to windows(battery life time and fan noise)

  I noticed that (with psense) temperature takes only 2 values : 44°c
  (fan off) 55°c (fan on).

  this is my first bug report, please tell me if I made any thing wrong
  thank you .
