Title:
  1002:9553 [Dell Studio 1555] laptop runs hot, shorter battery life,
  fan always on

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  On Karmic (2.6.31 kernel) my laptop ran silently (no fans unless
  really put through its paces), had long battery life (3.5 hours), and
  was cool.

  Since upgrading to Lucid beta-2, it runs hot, the fan is always on
  (from cold start it's off, but quickly comes on and stays on) and
  battery life is less than 2 hours.

  Lucid Kernel: 2.6.32-20-generic #30-Ubuntu SMP Mon Apr 12 15:20:57 UTC
  2010 x86_64 GNU/Linux

  Laptop: Dell Studio 1555 with ATI graphics (but using OS driver).

  Happy to help try things -- be great to get my laptop working properly
  again!
