APC UPS query

    OK ---another very elementary question. After having a bit of a scare (power
    outage last week; computer acted very flaky for a few hours but has been
    working fine since) I took the advice of many on this group and today
    purchased a UPS.

    I bought the APC Back-UPS ES (500). I got it for $47. at Sams Club. It
    seemed to be a good deal for my basic DIMENSION 2400 system.

    Now, my question. I installed the Powerchute software. It seemed to install
    just fine but it never asked any questions during the installation. So, my
    question is what will it do??

    Specifically, if I am gone and the system is on and there is a power
    failure, will this software perform an orderly shutdown? Will it save open
    files (suppose for some reason there is a WORD or WORKS file open)?

    You can open it and adjust the settings. However,
    the defaults are to beep every 30 seconds when
    the power fails; throw up a warning at 50% battery
    and shuts down at 10% battery power remaining.

    Of course if curiosity is got to you, simply pull the plug from the wall and
    time it out. It should do the job and save and shutdown the system in an
    orderly fashion. APC used to suggest that you test the UPS in just such a
    way but I am not sure if they still do.

    I have the same model. APC recommends that you enable Hibernation and
    in the event of a power outage and you're not around it will put the
    system into Hibernation, saving your work. If you don't have
    hibernation enabled, or it dosn't work, it just shuts down. All
    Office products, Wordperfect, and most others will allow you to
    recover a "named" file in the event of a shutdown.

    I guess the moral is to save any open files you're working on before
    you walk away. The couple of times I've lost power it gave me time to
    shut down everything and turn off the computer while power was out.
    Had I not been there I wouldn't have lost anything, since I save
    before leaving the house even if I'm not turning the machine off.

    Note that this UPS is a bit optimistic in reporting how much time it
    will run your computer. Mine says 17 minutes, but in reality it's
    more like 8-10 minutes with my 4550.

    Yes, APC still suggests that, so I did it. One concern:

    I followed the suggestion and all worked fine HOWEVER: I created the outage
    for 14 seconds (and then plugged it back in). But then the battery capacity
    was at 87%. Does it lose capacity linearly?? At this rate, the battery would
    have been dead within another 90 seconds or so. If that was truly the case,
    then shouldn't the computer have been shut down?? I really expect 5-12
    minutes of available battery power.

    Not linear at all. I have found that even with less than 100% capacity,
    there is still a fair amount of runtime left.
