Osprey does not list the size of its laptop compartments. The only information Osprey provides is that it will fit most laptops other up to 17". I suspect they never tried putting a laptop in that was not a Macbook. I bought this in prep for a work trip because I wanted to simplify down  to one bag for traveling and lo and behold this 17" compartment can't handle my 15" laptop. My spouse's macbook pro fits perfectly but I am left looking for solutions else where. I will be returning this bag and likely will need to try a different company that actually posts their sleeve sizes.
