Laptop dropped, making buzzing noise

[Mirrorz3dge]

a mate of mine dropped his laptop (acer travelmate 8372) from about 1.4m height, and it makes really really loud buzzing crackling noises. is it the busted hard drive? or is something electric in the laptop about to explode?

Such a noise could be a number of things, is it still booting up to the desktop?

I guess from your description that the noise is coming from the speakers, if you could just confirm that.
