Hello, does anyone have this problem? have you managed to solve it? It happens to me often lately.
It's a Dell Precision 5550 laptop.
Winver: Windows 10 Pro - Version 20H2 OS Build 19042.867
Intel(R) Wi-Fi 6 AX201 160MHz
Driver version: 220.127.116.11
The system was hibernated due to a critical thermal event.
Hibernate Time = 2021-02-20T03:49:42.124067000Z
ACPI Thermal Zone = Intel(R) Dynamic Tuning: WRLS_HOT = 358K
The error you report appears to be something related to the CPU or motherboard, or the laptop cooling fans(s), not wireless. I believe you need to try a different forum, perhaps processors or motherboards. I see you cross posted on the Dell forums. Please let us know if the suggestions there were any help.
Hopefully this (late) reply is still of use. The message is that a chip in the laptop is overheating. The "_HOT = 385K" is saying that that temperature sensor attached to the device is reading 385 degrees Kelvin, which is ~112 Celsius or ~233 Fahrenheit. The WRLS implies the wireless chipset but that is just a guess. For more information, dig into the DTT (Dynamic Tuning Technology) documentation.
Try putting the laptop on a cooling pad with some fans or use an ethernet cable instead of a WiFi connection.
