Re: Starting UPS

If your computer time keeps resetting, the CMOS battery on your motherboard is bad. It's a flat, quarter-sized battery plugged into your motherboard that you will need to replace.

Liebert gxt2-10000t230 low batt,bypass light flashing,no output,shutdown after a minute

Test outlet power by switching the unit to manual bypass and breakers off.
If power is supplied OK and the filter board repaired OK then restart the unit starting with the breakers supply to unit,battery confirm the display is on and static bypass led also on then switch back the bypass knob to normal and press the on button to switch the unit to normal.
Give the batteries time to charge 12hours then you can test the unit on backup mode.

Constant alarm but works fine otherwise


It probably burned up one of the capacitors on the board that signal the UPS to turn the alarm off. I've had this happen before and I unplugged everything, turned the UPS off, disconnected the batteries and then opened the UPS up to cut off the tiny, annoying, surprisingly loud speaker. I then put everything back together and that was the end of it :)

My ups won't stop beeping

The beeping on your ups is the sound of an alarm it will come on when starting up due to slow start circuit, there are a reset switch on the front display press once and beep will despair.

When switched the bypass to normal position, voltage failed through the unit; however the QB3 position gives output voltage

You didnt start the UPS correctly because the static switch was not on. The Static Switch has to be on to get a clean transfer of power. Check your static switch

After switching on the power supply, my pc takes around 3-4 minutes to start with APC UPS, earlier it was responding within half a minute

Have you taken it off the UPS and tried connected direct to an outlet.

Does it take the same amount of time?

If so you have a software or hardware conflict that is new and needs to be researched carefully.

try using the windows error log to see if there any startup errors.

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.

When I boot my PC up I get a blank screen and a message saying no signal then the screen goes into standby mode

OK, it's gonna be one of these 3 things :

1. The cable linking your CPU to your monitor might not be properly plugged or has been damaged. You should hence ensure that the connection between the two devices has been properly done and that the cable’s state is fine. 

2. You might be facing a problem with your monitor if the CPU makes a single beep error sound when you switch on the system. You can check whether the problem comes from your monitor by testing it on another CPU. If you still have “No Signal” error displayed including the error beep, I would strongly suggest you to try to get your monitor fixed by a competent technician or to get a new monitor. 

3. If you receive several error beeps when starting the computer, this might be linked to a graphic card dysfunction. You can refer to the motherboard notice or check that the connection has been properly set
