Windows XP Pro SP2, while setting up and testing new UPS and loss of AC power settings, my "Low battery alarm" & "Critical battery alarm" slider bars (under Power Options Properties) are stuck at 94%. I moved them out here for easier testing, but now I cannot lower either of them below 94%. The low battery alarm can adjust above 94% (94-100%), and I understand not being able to adjust it below what the Critical battery alarm level is, but the Critical alarm level will not adjust below 94%. Crirtical level will adjust between 94% and whatever the Low alarm is set at. So the real problem looks to be the Critial level cannot be adjusted below 94%. I have enabled/disabled both settings in every combination, but no help. Searched the web and this forum and not found any answer yet. Any ideas?
