Lenovo unveils lighter, quicker ThinkPad laptop

The Chinese computer maker displayed the new ThinkPad X1 Carbon on Monday and said it would go on sale later this month.

A Lenovo vice president, Dilip Bhatia, said it will have a longer battery life and lighter weight. He said that was in response to demands by customers who want a tablet's convenience but need a notebook's wider range of functions.

Lenovo acquired the ThinkPad brand with IBM Corp.'s personal computer unit in 2005. Lenovo passed Dell Inc. last year to become the second-largest PC manufacturer after Hewlett-Packard Co.
