Google​ account gone after Power loss.

Hello, I recently bought a 98c755. I love it but I have an issue. Where I live (Thailand),​ there are power outages from time to time. When it happens, my Google account is logged out when I start the TV. I need to login again. My apps positions on the home page are also reset. I don't think that's a normal behavior. I can recreate the issue at will if I unplug the power cord. Any advice?
