The simple answer is no you shouldn't. GE60 20C doesn't come with a backlit keyboard. Backlight is not even optional. GE60 2OC is advertised and comes with a simple Steelseries keyboard without backlight. Nowhere is a backlit keyboard listed or advertised for that particular model: http://www.msi.com/product/nb/... / http://www.msi.com/product/nb/...
Only certain models do come with a backlit keyboard like NexumxRaptoR's GE70 2OE (http://www.msi.com/product/nb/... ) or the 15.6" version GE60 2OE (http://www.msi.com/product/nb/... ). As the key for the backlight is therefor without a use it is used for the Dragoon Army shortcut.
If you compare the product images of a O2C and O2E notebook you should also see the difference in the product image.
