Two possibilities come to mind. 1) The battery has failed and can't be charged fully (usually one cell fails and it won't charge fully). I've diagnosed this by removing the battery and trying to charge it with a variable power supply. You can try replacing the battery.
2) The UPS itself is faulty and can't charge/maintain the battery. The entire unit should be replaced.

I recommend solution 2. I had the 725VA in this consumer UPS line and when I replaced the battery, the UPS could not keep the battery charged with any load on the unit.

Check your warranty, though. The APC warranty is for 2 years on this model.

I hope this helps.

My dell laptop latitue D600 makes noise & won,t boot up

what kind of noises does it make, beeping, clicking, a muttered plan about slaughtering all humans?
if beeping, check to make sure that your ram is properly seated, (unscrew the cover on back pop it out and put it back in make sure it snaps into place).
If clicking, probably the hard drive (i had the same problem on mine) the good news is its pretty easy to swap out, the bad news is you might not be able to salvage anything on the old one. (now is when you will feel really smart if you have been doing regular backups)
If computer is muttering about killing all humans, unplug it remove the battery and contact local exorcist. hope this is helpful

My sony vaio VGN-CS11S is soo noisy

The fan's bearings are probably going bad, or there may be some object that was sucked in to cause the noise.

I've almost thrown my phone out of the window because of this problem. I really need a solution, I tried changing my charger and cleaning out the socket where it goes in but nothing works. it Just keeps beeping and beeping. This isnt really a solution, more of an agreement of how annoying this is!!

It's beeping because the battery is completely dead and needs to charge. If beeping doesn't stop after a while of charging, you may need a new battery or a new charger.
