We recommend and support the use of BookBook with Apple MacBooks. We can’t comment on the fit on other laptops. However, if you measure the outside dimensions of your laptop and compare them with the outside dimensions of the various MacBooks, you can determine if it will fit or not.
Please note, however, that this is a hardcover case so it is very unforgiving of excess size. So if your laptop is too big in any of the three dimensions, it won't fit. There's absolutely no 'give' to this case. And there are no internal restraints in the BookBook so if your laptop is significantly smaller, it may shift around inside the case.
