Hi, I have an issue where two cores of the CPU are being constantly used 90-100% by two processes: System and System interrupts. This issue was present out-of-the-box with no internet connection and persisted after driver updates. Then I made a clean install of Windows 10 first without, then with internet connection, same result. I don't think that I'm alone with this problem, because I've seen it in this review at 7:10 Any tips how it can be resolved? Thanks
I did some troubleshooting. Got this result out of recording for a minute with Xperf: What does the TDP unlock matter if the processing power is hijacked by an error. If I don't get a solution to this issue in two weeks, I have to return this Mini PC.
Hi WereW, First of all, thank you for your support and welcome to the forum. You should find out what applications in the background trigger that usage. windows update? windows defender update? or something else? A brand new device, like the reviewer got, takes time to complete all the pushed updates when first connected to the Internet. I would suggest just leaving it there and let it does its job and check it back another day.
This is with TDP unlocker @ 12W and 16GB of RAM, I've observed for over 30 minutes and CPU usage is normal, which is below 5% for most of the time. This testing device has been fully updated from the Internet already, and it's from the exact same batch that you've got (hardware & original software), so don't worry about the hardware! Just check the drivers and programs and patiently wait for all the updates to be pushed and installed. By the way, this is the driver you asked for on YT: https://www.pepper-jobs.eu/downloads/index.php?file=GLK_UC2X_TypeC_driver_Win10.zip
The normal behaviour (what I mentioned on YT) was short lived, I only noticed it later. I've found the driver right after the YT post and before installing it I noticed that it's back to old behaviour. Right now the PC has been on for two days with multiple restarts, no change. No updates were installed. The CPU usage is from the multiple threads that ACPI.sys is creating from hal.dll and the interrupts from it. So far I never had anything like this on any of my clean installs, and I made two clean installs with the same 1809 install media on other devices.
Our device is with win 1809 too, but instead of a fresh install, we got pushed the update and upgraded from 1803. What I can think of would be drivers for now. We are having the exact same hardware so it has to do with software.
ACPI.sys is pointing to the drivers as well, could you please make a dump of a list of your drivers so that we may compare?
We are uploading the complete driver package to our FTP server today, you will see them up here tmr. Then you may try manually installing them to see if it fixes your issue.
This is captured straight out-of-the-box, right after the 1st login attempt, both system & system interrupts are normal. It doesn't seem like a new system would give 19000+ counts in "System" for 1 minute. Another thing, both upgraded 1809 unit and the original 1803 unit do not have those devices you captured on screen?
I won't be home until weekend, but I uploaded the *.etl file if you want to study it. I hope this could be fixed with your drivers, but I already tried many things with drivers. (btw. why aren't they on the homepage?) I even reseated the wireless card and the memory too, in hopes that it got bumped out of the ideal position in the shipping.
Here are my opinions. Hope that can do a favor for U. There are two reasons. 1.The new "clean" system U have installed got a function called Advanced Power Management Model. Coz my surface has the same situation. 2.I am not sure if it is because of the original system is Win10 Pro and your new system is Win10 home or not. Maybe their drivers are different. U could try to find the driver signing then u may find out who is the criminal. And forgive me that I don't know why you wanna re-install the system. Win 10 pro is really worth much money. BTW. My device is doing well after updating all the drivers.
Hi Bell, thanks. That's only the USB-C driver (because the latest Windows cannot install it automatically). We are also uploading complete driver package to our forum FTP now. (Done)
https://www.pepper-forum.com/index.php?threads/windows-driver-package-for-glk-uc2x.18/#post-170 Install all the drivers should solve your problem.
Update: Today I installed the provided drivers, except nr. 3 and 5, those exited with an error: PC doesn't meet requirements. No change in CPU usage. Redownloaded windows iso, put it on a new usb drive and did a clean install of windows to get rid of my previous failed attempts. No change in CPU usage. Didn't change ANY settings after install, waited for updates and (bloatware) app/game installs to finish, and only after that proceeded to installing drivers. after Type-C install - (this was the only time ever that only core0 was used) after other drivers, except 3 and 5 - after wireless/bt and graphics drivers - when I tried drivers 3 and 5 - What now?
