Chinese computer giant Lenovo has launched six new ThinkPad notebooks which the firm said offers a higher level of productivity for mobile business professionals.
"Inspired by our customers, the 2011 ThinkPad laptops deliver the best technologies the industry has to offer, enabling users to do more with their computing experience," said ThinkPad marketing boss Dilip Bhatia.
The T420 is particularly notable for offering up to a claimed 30 hours of battery life with an extended battery while even the standard battery manages 15 hours of run time.
The super-thin ThinkPad T420S can be pushed to 10 hours with the standard 6-cell battery and an optional optical bay battery. The standard ThinkPad T420S weighs just 1.78Kg.
Lenovo claims the firm's T and W series are the first business class notebooks to offer Nvidia's Optimus automatic graphics hardware switching technology which the firm says provides 33 per cent battery battery life over previous models.
All of the new models feature Intel's Sandy Bridge chipsets and include Lenovo's Windows boot-speed boosting technology which the firm says provides a 30 per cent boost to Windows boot speeds.
The notebooks will be available at the end of March. The sleek T420S is set to go on sale for around £1099 or $1,329.
