G5 and UPS

Message #1 - Posted 2005/02/22 - Thomas Hauber

Just got my new G5 and have hooked it up to an APC UPS backup. Although the G5 will show the percentage of power left in the UPS the time left is marked as "unknown". Is this typical? Will this work correctly with the energy saver settings when they are in time only?

I have a freebie APC UPS and it says the same thing on a B&W G3. Let it fully charge then cut the power. It should estimate the remaining time in a few minutes.

The G5 is a power hog. You might want to set the Energy Saver configuration to sleep as soon as possible when running on the UPS. You could probably get 10+ hours of backup time from a small UPS if the computer is in deep sleep.

You probably won't get anywhere near that long of a time. First action the G5 will take when it gets a signal on the USB line from the UPS is wake up. It needs to do that to determine what just becam active on the USB port and run the Energy Saver software to determine if and when to start the shutdown. About the minimum size UPS to use with the G5 is 750 VA, and 1000 VA or more would be better.
