I have a 17.3 inch HP with a 2" height from the extra large battery it has. I love the computer! However, until this case, I was having issues carrying the thing with me. I found this, I thought on e-bags, but they have no record of it. I have plenty of room, it iw very well organized. I can even carry my Nook (original in its case) in one of the interior pockets in front. There was more than enough room for the adapters for all things electronic that I carry with me (phone, nook, computer). This is an 18" computer bag but the adjustable side bar helps wtih the extra room in the main computer compartment. My Power cord went on the side. I have a wireless mouse that I park in one of the pockets in the front zipper compartment with my nook. My travel wallet has room as well so airport travel will be much easier. Oh, I also carry the card reader from my Brother Embroidery machine to work on designs when I travel--yes, I have more than enough room left over. Great bag!! awesome design. Your cell phone? has its own place in a small zipper pocket on the very front--away from everything and very easily accessable.
