The Lenovo ThinkPad 2011 notebooks feature Intel’s 2nd Generation Core “Sandy Bridge” processors with Turbo Boost performance optimization technology, while Lenovo Turbo Boost+ enables the laptops to stay in Turbo Boost overclocked mode even longer by keeping processor temperatures below required thermal limits. The notebooks also sport “all-day” battery life in select models, Nvidia Optimus switchable graphics in the T and W series, Intel vPro system management technology, and improved video and voice communication.
According to Lenovo, the ultra-thin ThinkPad T420s delivers up to 10 hours of battery life with its 6-cell and optional optical bay battery combined. The sub-four-pound laptop “speeds up boot time 30 percent” and includes the latest Dolby Home Theater v4 audio. The thicker T420 has a battery life of “up to 30 hours” with the standard and extended slice battery combined, while the W520 mobile workstation delivers “twice the performance of previous models”.
