When I open energy saver I can see no drop-down menu or UPS tab... Is this in both Tiger & Leopard? Goes it only appear as an option when the UPS is connected?
Although I installed the APC PowerChute 1.3.4 (the version that supports Intel-based Macs, which is what I have), I ended up trying to use the 'Energy Saver' tab-> UPS (settings) -> UPS.
In there, I set it to have the computer :
1) Shutdown the computer when it has been on UPS power for : 5 mins
2) Shutdown the computer when the time left on UPS power is : 15 mins
3) Shutdown the computer when the UPS power level drops to : 70%
I unplugged the UPS from the wall and watched the timer tick down, and the battery capacity drain... it was unplugged for well over 10 mins (criteria 1 should have fired, but didn't), it went down below 10 mins left on UPS, based on the tool bar indicator (criteria 2 should have fired, but didn't), it went down to about 45% full (criteria 3 should have fired).
Net result, I didn't wait for the Mac to crash, eventually, I lost in the game of chicken, and plugged the UPS back into the wall, with about 7 minutes of UPS time, 40% of UPS Battery Level, and having unplugged the UPS for about 10 minutes +.
Why is the Mac not shutting down ?
I do have the cable plugged into the UPS (APC UPS ES 650 G), and the other end is plugged into the USB port (I'm guessing I have that connected right, otherwise, the tab wouldn't show up in Energy Saver, and I wouldn't have the information about the UPS status available to me on the Mac).
Just for completeness ... I went to the APC PowerChute setting in System Preferences, and set the "Keep my computer on as long as possible by shutting down when the battery runtime is less than "10 minutes".
So, again, something should have fired, as I had 8 minutes left.
