There are a number of things you can do to protect your laptop in a backpack. One way is to use a padded sleeve or carry it in one of the compartments that are specially made for them. It is important to avoid carrying heavy items in your backpack for long periods of time. When you have a lot of weight in your backpack and you wear it for a long time, the straps can snap or tear and cause serious injury. There is also the danger of back strain when you carry a heavy backpack for long periods of time. You should only use your backpack to carry lightweight items like pens, paper and other supplies. If you have a lot of books to carry in your backpack, it may be better to get one of those rolling backpacks that hold more weight than the average backpack.
