It might measure 15.6 inches, but the Lenovo Legion Y740S Slim Gaming Laptop is super portable. That’s because this is a lightweight and thin gaming laptop. In fact, the Legion Y740S weighs just 1.7 kilograms—that’s about 3.7 pounds—and is only 14.9 millimeters—about half an inch—thick. It’s almost unbelievable how much power Lenovo fit in this small, entirely aluminum package. It supports up to 4K Dolby Vision HDR for incredible image quality. And it also works together with an external GPU, the BoostStation through its Thunderbolt 3 port. To wrap it up, it runs on Windows 10 Pro. Furthermore, its Vapor Chamber ensures that this laptop runs super quietly. Are you gaming in class? Your professor will never know.
