Hello,
I have a 7720 and over the last couple of weeks the laptop has powered itself off about 6 separate times during gaming. The most recent time today it happened only 5 minutes into a game.
The laptop makes a clicking sound, the screen turns black and it shuts down all within about 1 second.
I'm running the latest BIOS and I have tried both the latest NVIDIA drivers and the Dell recommended ones. I have run the My Dell diagnostics and the laptop passed everything, including the GPU tests.
I really like this laptop a lot, but it's not going to be much use if I can't run games for more than a few minutes without it switching off on me - and the game it happened in today, Football Manager 2014, isn't a particularly graphically intensive one.
Any and all help is appreciated. Thanks.
