Workstation-class performance.
Think it's just another laptop? Think again. Designed to outperform standard laptops, the W520 is actually a mobile workstation — lightning-fast, heroically powerful and surprisingly portable. The work starts with the processor — from 2nd generation Intel Core i5, up to Core i7 Quad Core Extreme, to keep your heavy-duty applications running flawlessly and boost your multi-tasking by 20 percent. Supplement that with the NVIDIA Quadro 1000M or 2000M graphics card with 2GB VRAM, professional-class graphics cards designed for up to 5x faster 3D performance and 8x faster computational simulation. Choose up to 16GB DDR3 RAM and you have one serious workstation — tested and certified by leading ISVs for more than 120 applications, including some of the most stringent in the industry.

Features for power users.
Performance like this should include the most advanced features — and it does. Powerful graphics require a display that lives up to what they have to show; feast your eyes on our 95-percent color gamut LED display in HD, HD+ or FHD. For the most accurate color workflow, opt for the industry's first embedded X-Rite Color Calibrator. Transfer files 10x faster with USB 3.0, depend on the 34mm ExpressCard and MMC slot or optional Smart Card reader, avail yourself of the multiburner combo drive and enjoy our best-in-class, ergonomic keyboard and Ultranav with our TrackPoint and touchpad. And when you're ready to talk about all the work you've done, you'll get superior Web conferencing and VoIP, thanks to full-duplex voice transmission support, dual digital microphone modes with advanced noise-cancellation technology, optimized speakers and a light-adaptive, 720p, HD webcam.

ThinkPad reliability.
Anything that works this hard is bound to go with you everywhere, so it needs to be tough. This brute has passed eight rugged miltary specifications tests and comes with legendary ThinkPad durability features, such as an internal roll cage, spill-resistant keyboard and Active Protection System to prevent data loss in the event of a drop. You can also rely on security measures such as Rescue and Recovery, self-encrypting drives, Hardware Password Manager, fingerprint ID and BIOS port lock for peace of mind. Even the environment can rely on the W520, with eco-friendly features including reduced greenhouse gas emissions, lower electricity consumption and compliance with RoHS, ENERGY STAR and EPEAT Gold standards.
