Why does my LAN card go off line?

The DC line gets it's power from the AC adapter that makes the DC that operates your modem. If your UPS is slow switching the power supply in the PC will drop out enough to require a restart. This situation, if it happens a lot will damage the PC since the hard drives don't like to have power interrupted in the middle of a read or write operation.

Stupid electronic controllers! Is there ANY way to make it resume 'previous state' after power outage? The **** thing shuts OFF when the power goes out for even a milli-second. As I live...

It won't be cheap because of the power a decent AC demands but an appropriately-sized "on-line" Uninterruptable Power Supply (UPS) supplies power from internal batteries continuously but when AC is available, the batteries are just paralleled to the line so any appliance plugged into the UPS never notices the power failure; at least until the batteries are exhausted. Since you didn't include the make and model, no one can tell you the backup capability you need or which voltage it requires (120 or 220VAC).

I hit the button to turn it on it will stay on for awhile and then it will start beeping really loudly an shut off

With your UPS turned off, unplug your PC and all other devices from the unit. Then turn the UPS on. If it still beeps and shuts off your UPS internal battery may need to be replaced or you have an internal UPS failure. Look for a red "battery alarm" light on the front of your UPS.

If the UPS does not shut down with all devices disconnected from it, Power off your monitor and look on the back of the monitor for a label which will tell you the amount of power it requires (probably 100 watts or less). Plug the monitor's AC power cord into your UPS and turn on your PC and monitor. With the UPS plugged into the AC line you are not using the internal battery and the UPS should remain on and your monitor should be working. If it shuts down you have an internal problem with the UPS.

Now unplug your UPS from the AC line (simulating a power failure) Your UPS is rated at 350 watts. Accordingly it should easily support the 100 watt load of your monitor. If the UPS continues to provide power to the monitor for 1 or 2 minutes down it's an indication that it's working properly and the COMBINED LOAD of your monitor. PC etc. when plugged into the UPS is exceeding the 350 watt capacity of the UPS. You will have to disconnect 1 or more devices from the UPS.

NOTE: Never plug a laser printer into an UPS.

If the UPS immeadiately shuts down after disconnecting it from the AC line with only the monitor plugged into it you have a bad battery.

How to charge ups for pc's

Your PC connection must always come via UPS, and your UPS will always keep charging.

UPS Power cable should be connected to DC, and your PC power cable should be connected to UPS.

And this way your PC will always be safe.

House power fluctuates, UPS and computer die.

Sounds like the internal battery of the UPS needs replacement. Contact APC and ask for a qoute for a replacement battery/service. It'll probably work out a cheaper to buy new.

Make sure you dispose of the old unit properly if you do replace

Comet 5-30KVA Battery problems when power goes off the battery no backup and the system shut down and error displays to battery

How old is the UPS? Have the batteries ever been changed? Sounds like you have open battery string(s), which would cause the UPS to lose power to load on loss of utility power. The batteries are your backup to the critical load. It only takes one bad battery in a string to compromise the entire string and render your UPS nothing more than a line conditioner.

When i Connect the power cable from ups to the power inlet on the server i get some funny noise. I try to put the machine on, no response.Seems no power getting the machine.

Maybe I am reading this wrong but it sounds like you are connecting the equipment in the wrong sequence. The service is plugged into the back of the UPS unit and the UPS is plugged into a wall outlet. The UPS is a power conditioner/surge protector that keeps your server from being fried if a sudden power surge goes through and it act as a back-up power source if you lose power. Try this new connection sequence and see if you have better luck.
