westom,
Your link describes the event more accurately than I did earlier. There was a loud continuous bleep when the computer screen went black and computer turned off all at once. I was finally able to get the bleep to stop by pushing the reset button and plugging the computer to the surge protector side only. So I took the battery out of the APC device and took it to the local battery shop today and it was shot.
So maybe a better description of the event was a computer lock up.
Also, if I read your post above correctly, theoretically one could plug a computer on the battery back up side and a laser printer on the surge protector side of the APC 600 UPS device and it should function appropriately, however the company discourages this.
