    with apple notebook, usually if the notebook's battery is below 5% the notebook immediately go to sleep whatever im doing at the time.

    with thinkpad or any other PC notebook, what will happen during a low charge?

    i hit 10% on my X300 and nothing happens.

    My T400 sounds an alarm that's (likely) similar to that of TMI-1 at Three Mile Island. :p On the two occasions it has done so, I've urgently sought an AC adapter and apologized to the notebook for upsetting it.

    Cheers,

    i've found this, anyone can confirm?

    http://windowsitpro.com/article/art...itical-battery-levels-on-a-vista-machine.html

    ideally i like an article about battery from lenovo or microsoft's, but searching lenovo webiste is a headache, all sort of irrelevant search returns, maybe someone is more familiar with lenovo site.

    so by default (in lenovo thinkpad) it should go to hibernation at below 5% is it?

    will i be able to wake the laptop again afterwards? like turn it on via the power button if it shut down/hibernating.

    i tried this on my macbook pro, and it wouldn't wake up, which is good. i wonder if this is the same on windows laptop too.

    On Thinkpads, you can set what the notebook does on 5%/10% battery in the lenovo power manager.

    ah just found out from power manager,

    the default is (which is what i got right now):

    at low battery [10%] warning notification

    at very low battery [05%] warning alarm, hibernate.

    something like that. or was it 10% that is warning alarm... hmmm... forgot :p

    anyway i wonder if on very low battery left, like 5-10% (battery light is orange) would the laptop be able to start up from shutdown?

    yeah, but that's about it. However if you put it in hibernation then you're safe till you reach a power source, and if you put it into sleep mode then you've probably got almost another 1 - 2 hours before it reaches 0%
