Spring Festival travel rush wants to bring a laptop, but there is no special computer bag. You should use an ordinary backpack. How can I better protect my computer?

The inner bag of selling notebooks can be directly sleeved outside the notebook, which is dustproof, shockproof and antistatic. It's good, and it's good to be at home at ordinary times. Then, if it is a backpack, put the book in the position closest to the back, and then put a big book outside the book, which is best to block the whole book, which can play a protective role. It's no problem to put other things outside the book, including hard things. Personally, I think the inner pocket of the notebook is still essential!
