I have a CyberPower UPS connected to a USB port. I am running Windows XP. The monitoring software, PowerPanel, looses communication with the UPS after odd intervals of time (used to be about an hour, now it's after about 3 hours). Is there a way to determine what processes are occurring in the background and when? I am wondering if something is interfering with the USB port or PowerPanel. I have made sure there are no tasks scheduled (Task Scheduler) and that Windows will not shut off the USB port to save power. Thanks, Kevin __________________________________ Do you Yahoo!? Yahoo!
