Try plugging the pc directly into the wall...if it works the UPS is defective.  You can order new batteries for the UPS online.

Computer will not start up only sometimes after it sits for days but after shut dowm wont start up again

Try performing a hard reset on the laptop by removing the battery, unplugging the Power Adapter and disconnecting external devices connected to the laptop. Once everything is removed/disconnected, press and hold the power button for around 15 seconds. Put everything back then power the PC on. The reason this issue happens is because the computer doesn't shut down properly and because of this charges get left on the laptop's motherboard, holding power button down with nothing connected to the PC drains these charges. If still the same issue exists, try updating Windows, there might be updates that doesn't install completely. Update drivers as well and run a system scan with your security software.

Hope this help. Goodluck!

When the power button is turned on my apc350 makes a high squeal sound, what is this? I have to have it turned on to use anything that is plugged into the battery backup outlets.

Double check the connections on the internal battery. If you have had the unit for a year or longer it may be telling you your back up battery isnt any good. I suggest replacing the battery, go here

APC ES350 strange noise

My solution was to unplug everything, hit the reset button, and then power the unit back up. The problem I found to be that I had my laser printer connected to the "surge + battery" side, and for some reason no laser printer can be connected to it.

APC back UPS 400 fails to give back up

I have the same problem with an apc smart-ups VS 650.


New batteries - charge in batteries is good (also tested under load).


When AC power fails, no power is supplied to PC connectors by the UPS.


UPS self test works fine. UPS does not report any problems via software - Power Management under Windows XP.
