Dear All,
I am facing this problem from last week that while doing work system gets shutdown with 30 second timer, the pop up of timer after few minutes appears on the screen which is so frustrating. last week there was same thing happening but also an error occurred which shows power cable issue so I replace both the power cables my switches are fine. I really don't understand what is happening. Its also generate no controller found error sometimes. While other than shutdown problem system works normally I am not facing any kind of problem.
