    A couple of days ago I replaced an old UPS with a CyberPower CPS425SL. I
    connected the serial cable and installed the software. Everything is great,
    I disconnect incoming power and reconnect it after a few seconds and the
    computer never misses a beat.

    However, if I let it time out to where it shuts down the computer (I set it
    to 90 sec), the computer shutdown nearly finishes but the UPS shuts off
    before the computer completely finishes the shutdown. I can't find any
    additional options or timers in the software setup, any suggestions?

    A larger rated unit, your's is too small.

    Please explain. Since you know nothing about my computer, how could you
    make such a judgement? According to the specs on the unit, I should be able
    to run my computer for at lease five minutes on the UPS. As far as I can
    determine, the problem is NOT that the battery is dying, it is shutting off
    per some timer.

    By the way, I get the same symptom if I use the scheduled shutdown function.

    In my experience, UPS units don't typically just "shut down" by themselves
    unless there is either a low battery, or an overload condition. When you set
    up the software to tell windows to shut down when the unit goes to battery
    power, the unit merely signals it's software, which initiates the windows
    shutdown process. AFAIK, the UPS should not cut power to the PC at all, even
    after windows has shut down properly. Either the unit you have is
    inadequate, or there is likely something wrong with it. I would exchange it
    for a new one.

    In the future, if you aren't familiar with the device in question, I suggest
    you simply let it go and maybe somebody else will have an answer.

    Quoting in part from the user manual for the device: "...The computer and
    UPS are automatically shutdown to conserve battery power..."

    The fact that I replied, doesn't prevent someone else from suggesting
    another possible solution. You asked for "any suggestions". I offered an
    honest and polite reply based on my own experience with UPS units in
    general. If you were seeking a specialist for your particular model, then
    perhaps you should have called Cyberpower. You posed a question in an open
    forum, where you can expect a wide variety of possible ideas and

    In fact, I asked a very product specific question.

    I have, in fact, sent an inquiry to CyberPower but don't expect any better
    answer than usual from such companies.

    I wouldn't expect much help from them given your demeanor.

    Cyberpower "425sl" is a 230 watt UPS. What is the power Supply rating on
    your PC's power supply? Now you tell me if it is sized correctly. There
    also, generally is a setting for "seconds to shutdown at depleted
    battery" (or some such wording as that) that is probably getting to you
    before your 90 sec setting is.

    What's with you? You ask for help and then jump on people when they give
    you possible causes. If you don't like the answers, don't ask the question.

    I ask a question about a specific issue with a specific make and model of
    device and I get a bunch of garbage telling me I bought the wrong device
    (without knowing anything about what I bought), telling me the device was
    working incorrectly without giving any reason for that supposition, telling
    me my computer was drawing more power than the device could supply (without
    knowing anything about my computer) and in general giving answers to
    everything except the very specific question I asked which was looking for
    somebody with experience with that specific make and model UPS.

    I wouldn't need to know many details either.

    1) Typically if a UPS shows that behavior it is because it is too
    small and is going into overload shutdown to protect itself from
    burning up. (Maybe you have a Pentium 4 computer and a 17" or larger
    monitor hooked to it? That's more than 250 watts draw right there)

    2) Something is wrong with your UPS.

    It's a damn short list and doesn't involve much more troubleshooting
    than that.

    You can ignore the advice if you want, but when people (like you) get
    an attitude after asking for advice for free...well, then they (you)
    go right in the killfile.

    Good luck in the future.

    Perhaps you did. That remains to be seen given that the problem has yet to
    be solved.
    Obviously something isn't working correctly or else you wouldn't be asking
    about it here.
    You provided no information about your computer, so what did you expect us
    to suggest? People here aren't mind readers. You want more specific answers,
    post more specific info about your system. People were making suggestions to
    the best of their knowledge based on the minimal info your gave.
    You hardly specified that you wanted answers only from people with intimate
    knowledge of that model in particular. You asked for "any suggestions".
    Nothing more or less than that. You got exactly what you asked for, and you
    turned out to be a prick about it. If the answers you got didn't fit the
    problem you have, then just be thankful that someone was nice enough to take
    the time to try and help, whether the info was ultimately helpful or not.
    All you had to say in reply to my suggestions was that the shutdown feature
    was normal for this model, but thanks anyway. But even that little bit of
    courtesy was evidently beyond you. Next time, no one is going to bother
    because of how you have acted.
    Thor, Feb 16, 2004
  14. Chet, what did you finally come up with? There are others who could benefit
    from your experience. thanks.

    The response from CyberPower is that after initiating computer shutdown
    (following a user defined timeout), the UPS is supposed to stay on for two
    minutes then shut off. They say there is no way for the user to change the
    time. I am actually getting a UPS shutdown after 45 seconds (regardless
    whether I start shutdown 10 or 90 seconds after power failure). Obviously,
    the UPS can't wait for an additional command from the computer because the
    computer should be OFF. This isn't a serious issue since files are saved
    and major programs stopped.

    Secondary problem is that my computer usually shuts down in 25-30 seconds
    but when initiated by power failure, still has not shut down completely
    after the 45 seconds the UPS is giving me. Something in the UPS supporting
    software seems to be preventing total power off but I haven't yet figured
    out what that is.

    I don't intend to pursue this with any particular vigor because the main
    reason I have a UPS is to (1) provide robust surge protection and (2)
    provide continuous operation through power drops of a few seconds and both
    those functions are working admirably.
    Chet, Feb 19, 2004
  17. I thought the UPS is supposed to stay on until the computer tells it that it
    isn't needed anymore (by shutting down, and thus no longer providing a
    signal that it is still in need of power). Or, of course, it runs out of
    battery. The user manual says nothing about any of this, but does say that
    the default "time between power failure and shutdown" is two minutes of
    battery life left - this might be what the CyberPower guy was talking about
    (then again, maybe not . . .).

    Is the battery dead after it shuts off, or is there plenty of juice left?
    Are you using XP? Have you disabled XP service for UPS?
    Have you checked your log file?

    This is the important thing. It may be failing to provide enough power
    because it ran out of power.

    I am quoting the message I got from CyberPower. If you don't like their
    design then I suppose you should stay clear of their product.
