This is my second rog laptop and never had this issue. Had this G751 for a few months and this just started happening about a week ago. When i shut the lid and open it back after a small period of time (1, 2 or more hours) it shuts down. Before it would resume from sleep but now no matter what power settings i change its not sleeping/resuming.
I have tried different power plans and also changed what happens when i close lid under power options. I have tried sleep and hibernate.
Anyone have this happen before?
