Plz, sorry for bad english. Since about 4 days ago, I could not do many movements with the notebook, like move it from a table to another place, etc., because it started the same noise of the video. But I could close it, put it in sleep mode, and turn it on again, that the noise would disappear. But now even this does not work anymore. The problem will be the fan, or the HD, as I think?
