The 418536U is the base model in Lenovo's higher-end Y650 series of IdeaPad notebook computers. Both models feature 16" LED displays and Intel Core 2 Duo processors, the 418536U clocking in at 2.40 GHz. It lacks the premium model's discrete graphics chip, but with 3 GB of DDR3 RAM, should perform well in mainstream home computing tasks. Both models feature 320 GB of storage space and built-in WiFi and Bluetooth. Windows 7 Home Premium arrives preloaded.
