The disappointing battery life of the ThinkPad X1 calls for a solution, and Android is Lenovo's response. By segmenting the function of a notebook with two platforms, the company hopes to improve battery life with Android-based "Instant Media Mode" when less power is needed. 

A Lenovo Live Update (which has been removed from the company's website) showed a new ThinkPad X1 Hybrid which seeks to address the poor battery life that its predecessor had, by adding a “Instant Media Mode” which is essentially an Android platform resembling that of the IdeaPad K1. The "instant-on" mode can switch to Windows 7 when performance and productivity is necessary, but otherwise, it boasts 10 hours of web browsing or 8 hours of multimedia experience. Plans to introduce the 13- and 14-inch Ultrabooks mid next year were also revealed, priced at US$1,300 and US$800 respectively.
