Disable beep on Acer AO722 netbook [SOLVED two ways]

The Acer AO722 is a lovely little netbook. However, it does have a few annoyances. One of which is that when using the netbook it will make an annoyinh beep, if you plug-in, or unplug, the power supply. I am not sure why Acer designed the A0722 this way, but thankfully there are a couple ways to disable the power plug beep! In Windows 7 go to: Control Panel > Sound > Playback Tab > Speakers > Properties > Levels
