Asus Eeepc 900 high pitch whine & screen freezing

[Uranium-235]

so, i'm fixing this for my friend. After getting the rootkits off, she still had the issue of having it in her backpack when a sports drink got part of it wet. Her keyboard has a bad right shift key, but under the shift key there is making a very high pitch noise. I kept moving my finger over the components and seem to have gotten the general area making the sound, picture attached, circled in red (with mspaint). Noise is no problem, but it (sometimes) has this freezing issue when you plug the power in (second attachment)

what does anyone think?

That's an inductor, for one of the buck converters. Getting it wet may have deteriorated the lacquer on the windings so they're loose and whine. Freezing on AC might be due to bad (or wet) caps or extra moisture still lurking somewhere on the board.
