Aspire A515-54 hung up or reboot
I just bought an Aspire A515-54 in January. I always keep the power on. But from time to time, the machine got hung up or reboot once a day or a few days. First time I find was in the morning the machine was reboot in the night. I thought it was some OS upgrade. After happening with multiple times, I felt it unusual. Recently I got some experiences of hung up. The keyboard and mouse don't response at all. And then I heard large noise of fan. It started running fast. I have to press the power button to shut down.
Another thing is, I tried to create a support ticket, but unfortunately I can't find A515-54 model. What can I do?
Thanks
