Balanced for business.

You hire top-tier employees; why settle for less with their business tools? These laptops maintain the industry-leading innovation of our ThinkPad portfolio while incorporating new advanced industry technologies. They offer the perfect balance of mobility, manageability and security — the best mix available for any enterprise-class deployment.

Top-tier performance.

The ThinkPad T420 and T520 laptops have the top-performance features every business-class user needs: 2nd Generation Intel® Core™ processors for a 20-percent increase in performance; Intel HD Graphics with twice the performance of previous generations; optional Lenovo RapidDrive SSD technology for faster boot time and improved application performance; accelerated bios; system driver maximization; increased battery life; Intel vPro™ technology; and more. We like to call their performance "uncompromising" — you ought to call it "yours."

Computing comfort.

On-the-go professionals will really enjoy these thinner, lighter models with a keyboard design considered "Best in Class" for those all-important, ergonomic concerns. They're also easy on the eyes and ears, thanks to the superior web conferencing capabilities of a 720p HD webcam and advanced noise-suppression microphone plus keyboard noise reduction technology. Comfort also means peace of mind, which users will have from knowing these laptops are durable — they pass eight rugged military specifications tests — and secure, thanks to features like encrypted hard drive technology with remote management support, integrated fingerprint reader authentication, Trusted Platform Module and Lenovo Hardware Password Manager, just to name a few. Toss in increased battery times — up to 30 hours with a slice battery — and Instant Resume for constant connectivity even in sleep mode, and these laptops are perfect for the hectic, mobile lifestyle of the business set.

Accessories that fit to a T.

When you take your laptop on the road, protect your investment with a ThinkPad Carry Case, available as a backpack or toploader. If you need optimal battery life, carry along the slice battery for up to 30 hours of computing. Back at the office, use it like a desktop PC with a ThinkPad Port Replicator Series 3 or Mini Dock Series 3, offering rear port cable management and connectivity. The Mini Dock Plus supports three monitors in addition to your laptop display, for a four-monitor configuration.
