Hi every1 i ve problem with my laptops fan. When i switch on my laptop fan
start working till i swicth off my laptop.I dont know why.Can you please help
??
 
Notebook fans run will run faster/longer based on temps that are sensed
inside the notebook housing. Most times the temp thresholds are values
set in BIOS. Notebooks run very warm. It's a good idea to install and use
a constant monitoring application that resides in your System Tray (by
time).
I would recommend SpeedFan 4.29 or if the notebook in question is a
Dell model, I'd opt for a specialized fan program that allows you to create
your own fan/temp control settings.

Your post wasn't clear on what type of Fan issue you're having ( Not
Running,
Running constantly....)

Laptop fans usually work the same way as the radiator fan in your car: When
it gets hot, it clicks on. When it cools off, it clicks off. Windows is
fairly poorly suited for laptops as it just keeps running the CPU full
blast all the time even with nothing running. Linux is a bit better on
laptops as Linux uses the CPU's HLT (halt) instructions to pause the CPU
when it's not needed, making the system run cooler with longer battery
life.

Lookup "SpeedStep". It's completely opposite of what you have posted.

All SpeedStep does is work around the problem of an OS that uses an idle
loop to soak up idle CPU time instead of using the HLT instruction by
slowing the CPU down. My point is, on a well-designed OS, SpeedStep is not
necessary except under the heaviest loads. Now if you use an OS that uses
HLT /and/ take advantage of SpeedStep, you're going to get fairly
unbelievable battery life.

But just for comparison, my IBM Thinkpad A30 gets about 2 hours battery in
Windows, but I can squeeze about 2:35 out of it on Linux. That's the OS
using HLT wisely instead of just making the CPU grind on some idle loop
when it has nothing to do that cycle.

You still have it backwards. SpeedStep is used to lower CPU speed, not as
you said, " My point is, on a well-designed OS, SpeedStep is not necessary
except under the heaviest loads." Under heavy load you want full processing
power not less! SpeedStep is supported under Windows XP with certain Intel
CPUs. If it's not necessary why does Linux support it? I thought Linux was a
well designed OS?

I don't have it backwards, neither do you. What we have here is a failure
to communicate. :o) My point is SpeedStep slows down the CPU under low
usage, which partially makes up for Windows inability to use the CPU's HLT
instruction.

Linux supports it because it does improve battery life, though not nearly as
much as it does under Windows. This is because Linux does use the HLT
instruction, essentially letting the CPU almost shut off during unused
cycles. Because of this, if you took two totally identical laptops, switch
to battery at the same time and leave them idle but powered on, the Linux
laptop will outlast the Windows laptop.
