Random Reboots When CPU Temperature Too Low

Hello,

I recently acquired a laptop Asus Rog Zephyrus G14 GA402R 2022. The previous owner reported some issues with random reboots if the charging cable is not connected; and this was with Windows. I tested the laptop and it worked really fine and since the charging requirement was not a problem for me, I decided to buy it. The previous owner also changed the cooling liquid on the CPU, but they said that this did not resolve the issue.

So after using the laptop for a while, the reboots got worse, as it was not enough that the laptop was connected to a power supply. For this reason I am utilizing stress-ng script which puts just enough weight for the CPU so that the device does not reboot. When using stress-ng the device does not have to be plugged into power supply, but this drains the battery very swiftly.

It seems that as I boot when the CPU is cold, I can at best get to the Grub menu when the machine reboots. For some reason the firmware interface heats up the CPU very intensely so I have the heat the CPU every time when I'm booting to around 70-80 Celsius so that I can boot successfully.

*So the issue is that without enough CPU temperature, my device randomly reboots.*

I have tried to diagnose the issue and I believe that it might be due to faulty hardware, or a ACPI related BIOS bug. I have tried all the officially availabe BIOS versions 317, 318, 319 and every one of them seems to have this issue. I have tested this with various different kernels and currently I have three kernels which can replicate this issue 6.15.2-arch1-1, 6.14.11-hardened1-1-hardened, and 6.15.2-zen1-1-zen.

Here are two ACPI related errors from dmesg that I could find:

[    0.322814] ACPI: [Firmware Bug]: BIOS _OSI(Linux) query honored via cmdline
...
[    0.396721] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PCI0.GPP0.SWUS.SWDS.VGA._STA.GC00], AE_NOT_FOUND (20240827/psargs-332)
[    0.396731] ACPI Error: Aborting method \_SB.PCI0.GPP0.SWUS.SWDS.VGA._STA due to previous error (AE_NOT_FOUND) (20240827/psparse-529)
/* ^This error above shows multiple times in a single boot sequence^ */
...

In every boot sequence I get the "Could not resolve symbol" error message displayed by Grub. It seems like the kernel is trying to fetch ACPI configuration information from BIOS, but is unable to resolve it.

Here is the output of acpi -V:

Battery 0: Not charging, 100%
Battery 0: design capacity 4769 mAh, last full capacity 4129 mAh = 86%

Cooling 11: Processor 0 of 3
Cooling 12: Processor 0 of 3
Cooling 13: Processor 0 of 3
Cooling 14: Processor 0 of 3
Cooling 15: Processor 0 of 3

*So my question is that is this possible to fix by for example tweaking some values from software side of things, or does this require potential hardware fixes? Could it also be that the CPU is weirdly soldered and thus, it has problems with electricity. And only after heat expansion it is able supply electricity normally.*

Re: Random Reboots When CPU Temperature Too Low

Please use [code][/code] tags, the BBS predates markdown by approximately your age. Edit your post in this regard.

Ryzens are notorious for that, see https://wiki.archlinux.org/title/Ryzen#Random_reboots and this also perfectly fits

For this reason I am utilizing stress-ng script which puts just enough weight for the CPU so that the device does not reboot.

Re: Random Reboots When CPU Temperature Too Low

It does sound like a hardware issue, considering the problem was present in windows too in some capacity. However it is worth trying to change cpu voltage/frequency/PBO settings in the BIOS, if you are comfortable with that. You'd need to google what are safe limits for your cpu if you increase the voltage, but it's also possible that underclocking (lowering the speed) would help.

Re: Random Reboots When CPU Temperature Too Low

I'm having a very similar issue on Lenovo Legion S7. You could to increase the voltage with the following command:

ryzenadj --set-coall=

The exact value I'm not sure of, try both increasing and decreasing it. I've been increasing it by 15-20, but try playing with it a bit.
