    Hi all,

    I just bought the new T410s in April. I used to get 3-3.5 hours easily on battery. Now, all of a sudden, I'm getting about 1.5 hours or less! For instance, when I started writing this it said 1:30 minutes left; now it says 1:05 and it took me a few minutes to write this.

    I don't leave it on A/C power for extended periods of time: I have it on battery every day while at school. Then I recharge it again when it gets down to about 10%.

    I recalibrated the battery today, letting it drain to about 5-6%: the point of automatic shut down. Then I fully recharged on A/C power. Unfortunately, this did not fix the problem.

    Cycle count is 152.

    Any ideas why this is happening? Or--more importantly--how to correct it? Ideally without buying a new battery....?

    Thanks for your help!

    Simple question first, have you got it set to the right power management scheme?

    check power manager/battery tab and see your battery condition. Let us know design capacity and full capacity.
    Anyway, if you want to calibrate you battery, let power manager do it properly for you

    Might be worth looking at the battery firmware update sticky as well.

    Does your T410s have the switchable video?
    If you don't have the proper driver it will use the nvidia video all of the time instead of switching to the intel.

    I would check to see what is running that usually isnt and if there are any settings that may be different in your power manager. I had a similar issue this past tuesday wehre I went from getting 8-10 to 1.5 at best. But mine turned out to be a bad patch that ran my wattage up to 28w even with everything turned down. Im re patched and back at 8.6-11w. :)

    Actually at 150 charges it sounds about right to me.
