My HP All-In-One 20-c081nt has the processor Intel Core i3-6100U, which is supposed to not run hotter than 100C. On Windows if 100C is reached, the screen will fade out and PC will immediately shutdown. A warning will be shown at next boot. On Linux, seen in the video, the PC will simply keep running as if nothing has happened and show the thermal shutdown warning after a graceful reboot.
Why does it force the processor over the limit in the first place?
I think in every other laptop the CPU just throttles when it gets too hot. Meaning it can never exceed the maximum temperature. I wonder if this is a misunderstanding or if HP actually did away with all of that and designed a laptop that will cook itself.
And it’s not even a good design decision to shutdown the PC if someone runs a game… Aren’t computers meant to run them? Why not automatically lower the framerate by throttling? Why shut down instead?
On Windows there is an odd way of throttling which only sometimes triggers and lowers CPU frequency to 1380 MHz. It is bypassable via custom power plan. As I said, it only sometimes triggers. On Linux iGPU is never throttled and CPU is throttled around 97 C to speeds slightly below max MHz. Shutting down is, under normal circumstances, for situations where throttling fails. I have another laptop which successfully throttles and keeps temps below 90C.
I’ve used laptops for more than a decade. And sure, in the early times thermal management wasn’t that elborate. But I really haven’t seen any laptop in many, many years that doesn’t do it with perfect accuracy. And usually it’s done in hardware so there isn’t really any way for it to fail. And I played games and compiled software for hours with all CPU cores at 100% and fans blasting. At least with my current laptop and the two Thinkpads before. I’m pretty sure with the technology of the last 10 years, throttling doesn’t ever fail unless you deliberately mess with it.
