A time comes in a company's history when it feels like it has reached a milestone, and Lenovo can definitely claim to have done so now that it has sold 60 million ThinkPad laptops, even deciding to mark the occasion with a hardware upgrade.

The ThinkPad series notebooks are known for being the early adopters of such things as protective roll cages and spill resistant keyboards.

These machines have now gone beyond the 60 million shipments threshold, with 14 laptops supposedly being sold every 60 seconds.

To mark this occasion, Lenovo has now outfitted its ThinkPad T410, T410s and T510 laptops with the NVIDIA Optimus technology.

This solution dynamically switches between the integrated and discrete NVIDIA GPU, depending on application load.

In fact, according to HotHardware, Lenovo actually modified the Optimus to allow both graphics solutions to work together.

The updated models are already selling through their maker's online store and Lenovo's business partners, at prices of $1,299 for the T410 and T510, or $1,849 for the T410s.

"Long recognized as a hallmark for innovation and excellence, ThinkPad has been the trusted laptop brand for business users around the world for nearly two decades," said Peter Hortensius, senior vice president, Think Product Group, Lenovo.

"With Lenovo, ThinkPad has grown even stronger for quality, reliability and performance, and we'll continue to drive our commitment to innovation further as we design future ThinkPad laptops."

"New technologies like NVIDIA Optimus are making ThinkPads even smarter," said Rene Haas, general manager, Notebook Products, NVIDIA.

"Never before has there been a solution that so effectively eliminates the tradeoffs between riveting graphics performance and long battery life. Visual content is the most popular and important form of data today, and we've built the NVIDIA NVS 3100M graphics processor to be the perfect processor for the task," Haas added.
