Question about APC (BK500TW) UPS System

Intermittent "On Battery warning"

I don't know what's up! I have my cable modem, CPU and Monitor hooked up and it recently began to cycle to On Battery for the standard four-beep warning at random times. Other times, sometimes during the same cycle, it doesn't make it to four beeps and then everything is fine for awhile! None of the other appliances hooked up to the same outlets show any change when this happens. Florida is notorious for "dirty" power conditions and I can usually see the results of dropouts and spikes in the lamps when they occur, but this doesn't seem to follow that pattern. The battery is 3 yrs. old, but seems to be doing well and it really hasn't been stressed more than a couple of times.

    KLPC,

    I found I had a driver problem that wrecked not only the keyboard function, but made some other undesirable things pop up. Like hanging characters in the stack, which made the cable modem hiccup and spontaneously reboot me! I installed a keyboard driver and it made it all go cuckoo! Since I uninstalled the keyboard, then reinstalled the generic driver Windows installs, my keyboard is still a little funny but it's better and no more probs with the APC or the modem! At any rate, look at any new drivers you've installed lately. Hope that helps!

Recheck your cables, particularly the VGA cable, it may not be seated well. Also, make sure the AC cord is fully seated at both ends since all modern monitors will put a warning on the screen even with no video (or sync) input to notify you that the monitor is ready but has no input. If nothing works, you may be the victim of a switching power supply in the monitor that will not start up any more.

Monitor says


Try and kill the bios. Find the jumper next to the battery on the motherboard and move it from position 1-2 to 2-3 ... press the power button a few times. then put the jumper back to normal and give it a shot.

I would disconnect the cables first before anything and attempt to boot the system.. if it boots, then start plugging hte cables one after another until you find out what's causing the machine not starting correctly.

Good luck.

System warning pop-up


Are you sure that nothing is overheating? If your cpu fan is turning too slow it won't disipate the heat. Do you have a program showing cpu temp:? I would take the access off the bottom and make sure the cpu fan is clean. If that is not the problem I believe you can turn the warnings off in the bios settings

Intermittent ring and now fading display


You may have the problem fixed by now; but I had the same thing happen to me with the same phone and also hooking up to a voip type phone connection. The person installing it hooked it from the modem straight to the phone. He didn’t know why and when he left I still had the problem. The problem being the phone would not ring. After thinking about it I decided to hook the modem phone line to my house phone wiring and then hook the phone to the phone house wiring. It worked and I am not sure why but I think that the house phone wiring is grounded and that makes more voltage for the ringer

if you cannot reach the BIOS settings screen at power-up, then try another known-good keyboard...it is likely dead.
