PC Perspective posted a review on the Lenovo T410s 14-in Core i5 Optimus Notebook

There are still those who to this day swear that Lenovo's acquisition of the brand was the beginning of a death spiral, but the truth is that ThinkPads continue to thrive. Lenovo recently celebrated the 60 millionth ThinkPad sold, and to commemorate the event they've added an interesting new feature to some laptops – Nvidia Optimus. The green team's graphics switching technology is now available on some T410, T510 and T410s laptops.

If this battery life issue was addressed, the ThinkPad T410s would likely have come out of this review earning an Editor’s Choice award. It scores highly in every other area. Normally poor battery life would not weigh so heavily in a review, but the T410s is a $1700 ultraportable. Laptops in this price range have little room for error, as other well engineered competitors are ready to knock you down and steal your lunch. The T410s, although a nice laptop, can’t compete with better options such as the Sony Vaio Z and Apple MacBook Pro.
