For starters, my fully charged laptop bag weighed 19.22 pounds (8.75 kg). What I discovered was that, of that amount, 13.84 pounds (6.28 kg) came from items that I considered absolutely essential. But the remaining 5.45 pounds (2.47 kg) came from items that didn't make any sense or that he only carried with him on certain types of trips. Most laptops weigh between two and eight pounds, depending on the size of the laptop.
My hand luggage bag weighs around 7.5 kg and my laptop bag with laptop weighs about 2 kg. If you're thinking of buying a laptop for school, you'll want a machine that's powerful enough to last you a long time, but light enough to carry it in a backpack. Laptops are designed to be taken to meetings or to be used anywhere in the world, so with the advancement of technology, the weight of the laptop is reduced compared to that of its ancestors. Since I'm compatible with several Mac and Windows users, my laptop bag includes a MacBook (13) and a powered Windows laptop.
You'll also want to make sure that your laptop is heavy enough to withstand being carried around while moving from class to class, so a mid-weight option would be best for you. On the other hand, lightweight laptops often lack the additional ports you might need if you use your laptop to make presentations at conferences and business meetings. These types of laptops weigh around 8 pounds and are similar to desktop computers, so obviously, if you have the options for ultrabooks and lightweight laptops, these types of laptops are redundant in the market because it's difficult to transport these heavy laptops. Yes, and the Kensington saddlebag has backpack straps, but I also carry all my clothes in a large travel backpack (which is even heavier), so I can only put them one at a time on my back.
If the laptop is solely for entertainment while traveling, for example, to use as a tablet for a child, an ultra-light option might be the best option for you. Lighter laptops are easier to take out of the bag often and easier to put back away, but if you plan to work mainly from one place, a desktop replacement laptop is probably a better option for you. The difference is that a good backpack distributes the weight well (and that's what I use for clothes), but the laptop bag fits tightly around the shoulder, even with a good padded strap. I usually travel with little luggage (a backpack for clothes and a bag for the laptop), so this is usually possible.
