Norton security version 22.9.4.8, windows 10, HP laptop. Usage graph does not function after wake from sleep or hibernation. I have read about many issues regarding sleep and hibernation with NS . I also have the none sleep problem. It's comforting to hear a reason like "the engine needs a complete overhaul". When will this happen?? Probably not in my lifetime. It's been broken for to long. Just now I went to find what version I have, and found that the events graph is also blank.
My last support contact had not a clue as to this bug. You would think that Norton would have notified users of the problem and offered a work around and projected date of fix. for now I won't sleep or hibernate.
I found a small program that will instantly turn off the screen of my laptop screen, thereby saving power. It might be useful for others . ScreenOff 2.1.exe Enjoy.
