I found the plug on the back to be a bit flacky. I suggest you unplug from the nas and the power from the wall, and hit the connector and plug with some cleaner lube. I've seen them spark when the connector was moved. And it's probably stuck in a funny state because of it. I'd be tempted to do a reset...hold down fuction, hit power, let go of power, continue holding the function down for 6 secs. I'll take a good 5 or so mins to boot back, and flash lights and restart, a few times, but it may fix it. Of course your settings will be gone but your data will be fine. ( someone pls back me up on this
and goodluck
