All models will come with various Sandy Bridge Core and Core vPro processor options, and are paired with NVIDIA Optimus technology allowing for seamless graphics switching between the onboard Intel and discrete GPUs.
The company is also introducing a new feature labeled; Instant Resume. Instant Resume will maintain the laptop’s WiFi connection for up to 99 minutes while the unit is asleep. This allows users to move within their WiFi zone, with laptop closed, without the PC dropping the drivers and having to reload upon resume.

Other notebooks such as the ultrathin T420s may run up to 10 hours with the standard 6-cell and optional 6-cell slice battery, while the 15.6″ T520 is expected to achieve 15 hours with a single battery.
