Power Loss Detected

Just installed WD Access and Sync on a spare laptop running Win10, and shortly after (within a few hours) I started getting a random windows 10 message in the notification section saying “Power Loss Detected on Port 1” of my PR2100. I was sitting right beside my other laptop which has the same software and is set up the same way, and I have not received that message on that other laptop ever (that other one is my main use laptop, whereas the one I’m getting the message on is a spare which was being updated).

Is this something to be concerned about? The PR2100 was not being used (no files being written or accessed as far as I know) when I saw this. Wondering if its just the drive going to sleep? But why port 1 only?
