I have an hp dv4 laptop running Ubuntu 10.10. While booting up, the laptop fan just runs excessively for a few seconds until the login screen appears. Then it functions normally for the rest of the session.
I've read somewhere that you can do some tweaking in boot options. When I checked it out it was given laptop fan always ON : Enabled so I disabled it. Now, while running the system the fan alternatively picks up speed and then slows down.
The laptop is not hot at all and the temperature is a bit cold here. Any help will be appreciated :)
