Hello. Just two days ago my monitor began to go into power save mode shortly after starting up the computer. Sometimes I can get to the windows load screen, twice i got to the desktop but only for a very brief period of time - not enough to do anything - but it usually goes into that mode only a few seconds after i turn the computer on. (The lights go from green to steady amber on the monitor). I have read people changing the setting for the mode from desktop properties and also in BIOS but i dont have enough time to get into either to check. I am connecting the monitor to my pc with a dvi cable. I tried a new cable and that didnt work. I have two video card in my cp and i tried cleaning all connectors and switching them around and tried all four dvi slots but still nothing. I moved my monitor to a friends and used his vga cable with his computer and the monitor worked. I do not have a separate computer with a dvi slot to test, but I did use an adapter to connect the DVI slot on my computer to the VGA slot on my monitor and still nothing. Any Ideas???

Plug the battery backup into a working electrical outlet. If the battery backup turns on when the power button is pressed, then the problem may be that the previous electrical outlet is faulty. Proceed to step three. If the battery backup doesn't turn on, proceed to step two.
Reset the circuit breaker on the battery backup. APC battery backups have a labeled circuit breaker button located on the unit near the phone line, fax line, USB, network and coaxial cable inputs. Press the button to reset the circuit breaker. Power on the battery backup by pressing the power button. If the battery backup powers on, proceed to step three. If the battery backup doesn't turn on, proceed to step six.
Determine if the battery backup is charged and providing battery power. With the battery backup on and plugged into a working electrical outlet, plug a computer monitor into one of the battery backup outlets labeled "battery backup plus surge protection" on the battery backup. (APC power supplies have some outlets that provide only surge protection while the other outlets provide surge protection plus battery backup.) Turn the monitor on. Unplug the battery backup power cord from the wall outlet. If the monitor remains on, the battery is holding a charge, supplying electrical power and the battery backup is working properly. If the monitor goes off, proceed to step four.
Charge the battery. Plug the battery backup into an electrical outlet and allow the battery to charge for 16 hours. This will fully charge the battery.
Test battery charge. Once the battery is fully charged, repeat step three. If the monitor stays on when power is interrupted to the battery backup, the issue is solved and the problem resulted from an incompletely charged battery. If the monitor turns off when power is interrupted, the battery within the battery backup is faulty and needs to be replaced.
Replace the battery backup unit. The unit itself is faulty. If the battery backup is under warranty, contact APC to request a replacement.
If the battery backup unit is over 2.5 years old then you will need to replace the battery. Go to your local electronics parts house or battery distributor. They will have the gel cell battery you need in stock. These units are just like small car batteries, after a few years of use they will break down and not hold a full charge. When this starts to happen the battery life is about to be over, it will hold less and less charge until one day no power at all and then the UPS will not power on. The UPS have a monitor circuit that will prevent them from powering up with a dead or missing battery. The replacement battery should run less than $20.
I hope this helps, if so please rate our solution.
Try only the computer and monitor - it may be overloaded, 485VA is around 400W only, so it won't accomodate much more than a standard computer + monitor. Especially a laser printer is very power consuming and should not be connected to any UPS.
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
If it has been ripped out of the back of the monitor, then you will need a new monitor. If it has an area in the back of the monitor where you can plug in one end of a power cord, then all you need is to buy you a cord that fits your monitor.
you have to have the power rating rated in amps of the bed...if the rating of your bed and the system are same or even less than that..(i.e. the rating of television is less than that of computer monitor,so u can connect tv for long time than monitor when power goes off ) then u can surely use it.....but it ll provide the supply only till the back up is stored in the battery,when the power goes off
