[QUOTE="chscag, post: 693551, member: 46727"] Machine is new? Take it back or give Apple tech support a call. The hissing noise when running on battery is a concern. High pitched whine when brightness is turned up is something I also experience when using my 22" Samsung external monitor. I'm not sure what causes it but I suspect it's the monitor backlight - especially at high levels of brightness. Regards. [/QUOTE]
