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.
