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.
Hi and welcome to the Forum 
Unfortunately you have arrived at the SUSE forum rather than the openSUSE forum which is at https://forums.opensuse.org (same username/login), since openSUSE 13.1 is way out of any sort of support, help may be limited. In saying that, have you checked CPU and system fans for dust build up, maybe the thermal compound on your CPU needs replacing etc…

Please note that this forum is for hardware issues relating to SUSE
Linux Enterprise Desktop (SLED) - since you have noted in the subject
line that you are using openSUSE 13.1 you should repost over in the
