Lenovo ThinkPad W520 15.6" LED-Backlit Notebook, Intel Core i7-2720QM 2.2GHz Processor, 4GB RAM, 500GB HDDD, Bluetooth, Windows 7 Professional

The Lenovo ThinkPad W520 427638U is a 15.6" Notebook Computer with a 16:9 antiglare widescreen display. The system features a comfortable, spill-resistant keyboard and Lenovo's UltraNav system for mousing. UltraNav combines a TrackPoint and a large multi-gesture TouchPad for precise cursor control. The included 9-cell battery can power the system for up to 10.8 hours.

The computer features a workstation-class nVIDIA Quadro 1000M 2GB GPU, perfect for use in professional 3D and design applications. The Quadro features 2GB of memory and offers full compliance to the Open GL and ISV standards. For those times when a dedicated GPU is not needed, you can switch to the system's integrated Intel GMA HD 3000 graphics processor - it isn't as powerful as the Quadro, but it uses less battery power.

The computer is powered by a quad-core 2.2GHz Intel Core i7-2720QM CPU, which can be overclocked to 3.3GHz thanks to Intel Turbo Boost. It is loaded with 4GB of RAM, a 500GB 7200rpm hard drive and a DVD burner. It boasts Bluetooth 3.0+EDR, dual-band 802.11n Wi-Fi, a 720p webcam and a built-in memory card reader. Windows 7 Professional (64-bit) is the installed operating system.
