New T, X and S Series Laptops Pack Haswell CPU

Lenovo has taken the concept of ‘all day battery life’ to the extreme by outing new ThinkPad laptops at Berlin’s IFA conference that can go for up to 17 hours using swappable battery technology.

The feature can be found in the Beijing-based laptop maker’s new enterprise 14-inch T440s and T440 models. They get an efficiency boost though housing Intel’s fourth generation i7 processor and can be fitted with a smart card reader for extra security.

Closing the divide between the chunky ThinkPads of old and more portable consumer ultrabooks, the new models are 20% thinner than previous outings and sport a 45% larger trackpad that supports Windows 8 gestures.

They can be equipped with a full-HD display, a 1TB HDD (or smaller SSD) drive, the latest AC 802.11ac WiFi and optional 4G connectivity.
