They will also have a download available to make Santa Rosa based ThinkPads that were bought before this announcement compliant with the Energy Star 4.0 requirements.
Excerpt from the CNET article:
Lenovo plans to announce Tuesday that all of its X-, T- and R-series computers with Santa Rosa platforms will qualify for the Energy Star 4.0 rating that goes into effect on July 20.
The Energy Star program, which is overseen by the Environmental Protection Agency and the U.S. Department of Energy, revised its voluntary set of energy efficiency standards for computers for the first time in over a decade. Among the standards required to garner an Energy Star 4.0 sticker is a decreased power consumption while a computer is idle.
They also announced the ThinkPad T61p, which is interesting (even if it has a 15-inch display) in that it’s one of Lenovo’s first offerings with “Ultra-Wideband” (UWB), something you’ll be hearing a lot about in the future. UWB is a next-generation standard for communicating with peripherals (think Bluetooth, only many times faster). When/if this will make it into the X series remains to be seen.
