As of today the company launched six ThinkPad laptops that focuses on Video Calling, Smart PC technologies & Battery Life. Lenovo is getting serious about battery power and claims 15 hours of battery life with the T420 that packs a 9-cell battery, T420s last 10 hours on a single charge thanks to its 6-cell and optional optical bay battery.
