The Back-UPS is a series of uninterruptible power supplies (UPS) made by American Power Conversion (APC).  Back-UPS units are line-interactive UPS systems, only running their inverters when the grid power is unavailable. The 800, 1200, and 1500 models are known to have encountered this problem.

Known Issues

UPS Unable to Power On or Charge

Causes

  • The UPS failed, causing it to improperly register line voltage, and causing it to go into battery mode. Symptoms include not being able to charge, or turn on. The unit may make a chirping sound when the power is held to turn it on, but will then not turn on.

Solutions

  • Replace the five 22uF 16V SMD electrolytic capacitors on this board. There are four near the middle of the mainboard and one near the LED at the edge.

Apologies for the bad state of the image. One SMD (C3.) has already been removed in this image. C41 was factory-replaced by a through-hole cap.
