Based on your question about needing a case for your Lenovo 80MJ laptop, I'd recommend either the Lenovo 15.6 Inch Laptop Casual Backpack B210 Black for R270 or the Lenovo Casual Topload Case 15.6 for R453. The Lenovo Backpack would be ideal for carrying your laptop around campus or to the office while distributing the weight evenly on your back. It's specifically made for 15.6 inch laptops like the 80MJ. The Lenovo Topload Case is a solid, protective option that will fit your laptop snugly and has padding to protect it from bumps and bruises when transporting it in a bag. Both are made by Lenovo so you can be sure they're purpose-built for your laptop model. Let me know if you need any other recommendations!
