Lenovo is adding a number of new laptops to its product lineup that is says offer improved wireless network and batter performance.

ThinkPad X61 and X61s notebooks and the X61 Tablet PC offer longer batter life as well as a 30 percent improvement in wireless capability featuring Intel dual core and Centrino technology as upgraded for its “Santa Rosa” nicknamed upgrades.

Lenovo is also offering a Lenovo brand 3000 V200 model that includes an optical drive and places as emphasis on multimedia applications.

Widescreen versions also are available.

The new models augment Lenovo’s release two weeks ago of new models that were the first to include Intel’s new Santa Rosa technology.
“As the traditional work place environment continues to change, customers are telling us portability, reliability, connectivity and security are most important to them,” said Marc Godin, vice president of Worldwide Notebook Business Unit for Lenovo. “We’ve engineered our latest ultraportable ThinkPad notebooks so that our customers can get the best from their PC in all of these areas.”

Wireless connectivity options include up to gigabit speeds as well as Bluetooth and wireless wide area networks.

Improvements enable up to 12 hours of power on a standard battery. A new “Battery Stretch” control can add additional hours of power.

Security has also been improved, Lenovo said.

The new Tablet model includes “Super View” technology designed to provide lower reflectivity, even in direct sunlight.

The laptops will be available in June with prices starting at $949 for a Lenovo model.
