Device powers off during high usage with display turned off.
I've observed the issue with my Asus Tuf Dash F15 running an i7-11370H 3050ti mobile. When the screen is off and during gameplay, it abruptly powers down once loading begins. During Cinebench testing around 7:58, it shuts down regardless of the timer setting—whether on Prime 95 or a 2-minute delay. The power settings don't prevent this behavior. Even when the display is up but inactive, it continues running benchmarks until completion. The fans are functioning normally, and I've replaced the thermal paste twice without any issues. When the lid is closed, everything operates smoothly, but when it's open, it shuts down predictably after a couple of minutes during tests or gameplay. The vents aren't moving air when the lid is up, which seems unusual. I've covered them and kept temperatures stable; no shutdowns occurred. It works fine on a laptop cooling pad, though not the most efficient setup. If you're using a case, any orientation—upside down, sideways, or with lids down—triggers the shutdown. I noticed slight temperature differences when using external displays: temps are about 5-7 degrees lower with external screens, staying under 94°C. Turning it to external mode raises max temps to 97°C on one core and 95°C on the other. Before making any changes, I checked for updates and found the latest drivers for all manufacturers.
It might be the lid being closed too much. The temperature rises and the system fails. I think the chassis has cooling built in and preventing heat from escaping. Still, this is just guesswork. What if you left the lid open and turned off the screen, then test it?
It's definitely achievable. I'm familiar with ASUS laptops having vents on both sides, and they tend to get warmer when sealed up, even without shutting down. The situation can differ based on the model, how well the thermal paste is applied, and the cooling setup. You'd expect it to slow down performance (thermal throttling), but because laptops operate near their limits, it might happen faster than expected.
The keyboard stays very warm, and the lid traps the heat. Running F@H showed that opening the screen a bit helped, since LCDs don’t handle heat well and it could speed up aging.
I grasp your concerns fully, that’s exactly my initial reaction. For testing purposes, I left the screen fully visible and covered the keyboard/vent area to prevent airflow. As anticipated, performance dropped slightly—just a fraction of an inch. When the screen appears closed, it freezes after about two minutes during a Cinebench session, with no other processes running. If it shows as open, nothing happens. I can launch Cinebench or Prime95 whenever I want to increase power consumption and see GPU strain, but it still runs smoothly. I’ve attached images showing the screen height difference. It’s not significant enough to affect cooling much. Usually, I handle these issues by troubleshooting online or checking logs. This problem, however, is puzzling because changing the screen state seems to impact performance noticeably. Opening it throttles and running all day with a 1/8th inch reduction works fine. The top image is on, bottom off. Updated: checked the even viewer; the error description reads: Miniport Microsoft Wi-Fi Direct Virtual Adapter #2, event Fatal error: The miniport failed a power transition to operational power.

In summary, after checking the error code in the log, I looked into Device Manager and turned off the Microsoft Wi-fi Direct Virtual Adapter and NDIS Virtual Network Adapter Enumerator. Once disabled, the laptop performed much better. I’m not sure how this relates to the issue I’m facing, but I can close the lid now and run it normally without any problems.
