Swift 3 - Sleep and heating problem

gfgb

Hi!
I have a 2 months old Acer Swift 3 SF315-41 with AMD Ryzen 2700U; the BIOS and the drivers are all up to date.

I've noticed that the cpu temperature tends to go up easily (never exceeding 76 degrees celsius), particularly when using the browser, and the fan becomes quite noisy when it goes over 60 degrees.
Since, at the moment, I don't need a lot of computing power, I've tried to mitigate the problem by limiting the maximum cpu usage in both my operating systems, through the "edit power plan" options in Windows 10 and "cpufrequtils" in Ubuntu 18.04.
This fixes the heat and noise issue but, for some reason, sleep doesn't work anymore, both in Windows and Ubuntu: the screen goes black, but the laptop remains on. Today I closed the lid and put it in my bag; when I took it out, all the surface was scorching hot and the battery was almost completely drained. Luckily, everything seems to be working fine.

If I remove the limit everything goes back to normal, but I'd like to fix the noise problem in some way; it's not terrible, but it gets annoying, and I'm considering returning the product.

Any suggestions?
Thanks!

When you edited the Win10 plan, did you also check to see what closing the lid now does? Jack E/NJ

Yes. The problem happens in both Windows and Ubuntu, and I used a different method to limit the cpu usage for each OS, so I think it's a processor problem.

I've temporarily solved the problem in Windows by creating a power profile with 80% maximum cpu usage, and setting it to automatically turn on/off when awakening from/going into sleep mode.

Since it does not depend on the OS I'm using, maybe the problem needs to be fixed by a driver/BIOS update.
Thanks for your answer

What is your BIOS version number? Jack E/NJ

1.04, the most recent I think.

Try experimenting with the BIOS Main tab lid options if you haven't already. Jack E/NJ

I ran it on my W7 Home Premium and unparked 3 CPUs. I checked resource monitor and all CPUs were working. I did a reboot and they are still working.I wonder why it's working in mine and not yours.
