    Hi guys,

    I am currently playinig around with 2 Thinkpads 410s. One has the discrete graphics and the other doesn't. I noticed that on the one that doesn't have the discrete graphics, I get about 5.5 hrs of battery life on medium power settings and it runs 7/8 Watts running WinXP, but on the laptop with the discrete graphics, I only get about 3 hrs of battery life at 12/14 watt running windows 7.

    Is there anyway for me to improve the battery life of the T410s with the discrete graphics?

    Thanks...

    @Andrew
    The T410s does have switchable graphics, but I don't think it has Nvidia Optimus as per the video. The screen blanks in and out everytime the gpu switches.

    Nice... But I see the power consumption and I just :eek: !!! I think that anybody who needs an ultraportable with decent graphics performance should better wait a couple of months for the Intel SandyBridge to come out.

    Lenovo website mentions Optimuns. And at the end of the video, the guy says it will be available from October 5 onwards (just a week ago!)- I guess the previous T410s came without the Optimus?
