I can reproduce a system / video blackout problem reliably. I am interested if anyone else can do the same.
In Chrome, the screen blacks out, the fan is triggered, the mouse cursor eventually reappears, and the system recovers.
BEWARE! In Edge, the screen blacks out, and fan triggers. However, it never recovers requiring a hard reboot.
Before you begin, disconnect from all docks and external monitors. USB-C dock with the native display disconnected seems to eliminate this problem. This occurs for me regardless if AC power is connected or not.
I had the OLED display replaced for another problem. I had the motherboard replaced for this problem but it still occurs. A total replacement is on the way. I will let you know if the replacement machine fixes this problem.
I return my XPS 15 7590.
I replaced it with a Precision 55540. It is virtually the same machine. So far none of the video issues. Microsoft Edge showing Twitter GIF search does not kill the machine. The app slows and corrects itself as it should. The machine heats up, fans kick on, but it performs nicely and recovers. So far so good.
Please let me know if the credit it being processed to the original mode of payment so that we'll go ahead and update the case status.
