I recently bought a refurbished Latitude e6400. There were no signs of heavy usage when I bought it.
It KEEPS on making this really loud noise. I thought it was the hard drive at first, but I changed the hard drive and the noise still exists. I think it's the CPU. I opened the laptop a few times to try and air dust the fan, but now I cannot access the CPU because the screw is stripped (AHHH)
Here is a recording of the sound: https://dl.dropbox.com/u/31400064/Annoying%20Noise.m4a I recorded this when the CPU temperature was at 36 degrees and the CPU Load was 8%.
I am running Windows 7 64-bit and the A32 bios.
Please help! Thanks
