UPS Communication After Win 7 Sleep Mode
I have just purchased a Cyber Power Pure Sine Wave UPS and it is working great except for one exception. Whether or not I use the included software, after my computer wakes up from sleep mode, windows cannot communicate with the UPS.
With the included PowerPanel software, the PC still things the device is charging if I cut the power after sleep mode. Without the software, windows reports that the battery is plugged in, not charging.
Since the UPS is connected via USB, I have tried disabling "USB selective suspend" in power options, as well as unchecking "allow windows to put device to sleep" for all USB ports in device manager.
