Though Lenovo's upcoming ThinkPad X220 ultraportable sports a powerful CPU and plenty of RAM, its potential battery life may be the biggest lure.
The X220 isn't on sale just yet, but Lenovo is providing an in-depth glimpse at its specs thanks to an online PDF. The details confirm that the notebook can run without AC power for up to 23 hours on a single charge via a slim external battery pack. But even without that external battery, the unit is capable of a still healthy 15 hours on its standard 9-cell battery.
Lenovo also says that a low power multimedia mode can boost battery life by 30 percent, while users can opt for either higher performance or better battery life through the unit's Turbo Boost+ mode, which builds upon Intel's built-in Turbo Boost feature.
Aside from the battery life, the X220 sports some other powerful specs. Using Intel's latest and now bug-free, Lenovo offers a choice of an i7, i5, or i3 processor. The 12.5-inch high-definition LED backlit display provides a resolution of 1366x768 with an option for in plane switching, a feature that promises better viewing at wider angles.
And as an ultraportable, the X220 weighs in at less than 3 pounds, according to Lenovo.
The machine can handle up to 8GB of RAM and provides a choice of either a conventional hard drive with a capacity as high as 320GB or an SSD with as much as 160GB of storage space.
Rounding up the list of features are three USB 2.0 ports and a USB 3.0 port available with the i7 processor, a 720p high-definition Webcam, and an Intel Wi-Fi/WiMax adapter. Lenovo also offers some of its usual features, such as a fingerprint reader as well both a trackpad and the familiar red trackpoint.
Lenovo hasn't yet revealed when the X220 will make its way to consumers or what it'll cost, but we've reached out to the company to see if it can share any further details.
