Dog... Chillax. It'll probably fit. If it doesn't, don't worry about it.

[/quote] That laptop won't fit in either of the laptop compartments (there are two) due to it's width, but [i]should[/i] fit in the main compartment of the bag. You have about 20-21" there. If you get a thin neoprene case to protect from scratches it should be fine. A case is a good idea regardless. [/quote] :( You sure? The back compartment looks very large and I measured it at just around 18.5" I hope it fits![/quote]
