I don't know anything about Microsoft or windows based computers. I am all in on Apple, from the iPod Classic to the MacBook Pro and everything in between. The best thing to do is to take your laptop into the brick and mortar store and do a trial fit. Stay off the .com places because you will be buying and returning till you get the case or sleeve that fits, and that is a long frustrating process that can be avoided with a simple trip to best buy.
