APC Back-UPS CS 500 does not power up?
The above device wasn't holding a charge, so I swapped out the battery, and it appeared to be fine for about a week.
Next thing I know, the "power" and "battery" lights were both on, but VERY dim indeed.
The device has now totally gone off and is unresponsive. I verified that the replacement battery isn't faulty as well.
Can anyone offer any assistance with this please? Thanks!
