Fan running continuosly, even when no apps running.

January 18, 2012 at 22:13:22
Specs: Windows 7
System : Dell 6510 (under warranty) , Windows 7, 8GB RAM etc

Tried installing latest BIOS, and replacing with a new battery.

Dell engineers recommend replacing motherboard, battery and fan. I found that the replaced motherboards are usually refurbished ones.

1. Are refurbished motherboards reliable. What are the odds that such motherboards do not give similar issues.

2.A refurbished mother board could be an older one that is repaired. So is it advisable to change it.

Read your manual to see if there is an option in the settings to force the CPU to run at full speed all the time. Running the CPU at full speed would probably result in the CPU cooling fan to run continuously.

Didn't the engineers mention that?

Don't double post.

Thanks for your reply OtheHill!,
No the engineer did not suggest the option of running CPU at full speed.

I am not suggesting that you do that. I am suggesting that it may already be done. Boot into setup when you first start up the computer. See if you can find a setting like that. Should be under power options.

If not in there then when in Windows look in control panel> power options.

If High Performance is checked then try a different setting.

Why would you replace the motherboard just because the fan is running? The fan is supposed to run.

"Tried installing latest BIOS, and replacing with a new battery"

Did you do this before or after the problem? Did you run thru all the settings, especially the power settings? Have you checked the CPU temp? If the CPU is overheating (or at least running hot), the fan will kick into high in an attempt to lower the temp. Did you have the case open for any reason? Is it possible the heatsink was disturbed?
