Laptop Making Squealing Noise

[ShookieJay]

I have a Dell Inspiron n5040 laptop from mid 2011 and i noticed that when the laptop is running off of battery, there is a squealing sound that seems to be coming from somewhere under the keyboard. I have an SSD so I've ruled out that it could be the hard drive and i know it also isn't coming from the speakers. I'm really stumped. Any help would be appreciated. Oh and one more detail I think I should add; it only seems to happen of I am transferring files over the network. So maybe faulty LAN Card?

It could be a cpu or gpu whine. I am not really a lan expert so if anyone knows what this could be please share.

Thanks for sharing. If it is a CPU or GPU issue, would there be a way to make it stop?

Just make sure that they remain cool is the main cause I would think. Also make sure that they are not too overloaded with things as I think this can cause it.
