My ASUS GA502 makes all kinds of noises. It has a loud coil whine when the keyboard backlight is off/dim, and the audio chipset is constantly popping the speakers by turning on and off to save power. I bought it open box; the buyer probably went insane from the noise before they could even set up Windows.
