Built Laptop Backpack

I try to buy a backpack for the college to be able to carry my laptop with my books, binders, etc. I think buying a North Face Jester. Would it be ok if I just put the laptop (in a protective tube) directly into the backpack, or should I buy a backpack that has a built-in pocket for the laptop?

And if anyone has suggestions to back, that would be appreciated, too. Thank you!

I use a mail bag, with a section Laptop Sleeve her.

I would really hesitate to stick it in a bag in an unsecured backpack with my books banging around. Can flex and damage the LCD. I saw it happen.

you do not have to buy a backpack with a built in sleeve
but one sleeve is suggested for protection
Best-buy a padded sleeve cool
