No! High CPU utilisation cannot he caused by a bad ThinkPad, only bad software.

 


Most 2018 ThinkPads currently have a firmware bug that does not acquire and release threads properly while initializing thunderbolt. Some operating systems may mitigate the problem, but the bug exists and *can* cause high CPU utilization.

I have only had my X1 for about a week or so now. Have downloaded only Firefox web browser and the LG Monitor software which by the way also seems to barely work. Downloaded that from LG website to work with monitor for screen splitting on Ultrawide monitor. Works for 2 days then it stops working and software app when opened refuses to recognize connection to monitor (says not connected). Have to them uninstall app and download it again for it to be recognized. Works for 1-2 days then stops working.

 

I have my Ultrawide LG monitor hooked up via HDMI cable to X1. Will try and see if CPU uses and memory are used as much when not connected to external monitor. For a brand new laptop this is pathetic. I may need to return mine for another new one at Costco.

Thank you for sharing. My laptop is brand new. About 1 week old with only 2 downloads on. I downloaded Firefox app and LG Ultrawide monitor app. Visited no porn websites. Your CPU and Memory numbers do not match mine. Could you try this for me also with Firefox so we could compare apples to Apples. ? I was thinking to myself that my X1 has 16GB of RAM while my iPad Pro has 4GB of RAM and the iPad Pro uses less CPU utilization and less RAM to open the same website pages. Something does not make sense here to me.

Do you by any chance have an external monitor as well? If so what kind? If so, could you link it to it and let me know then what CPU and RAM process is used? I was wondering if it could be due to high resolution on Ultrawide monitor perhaps or perhaps port connection of some sort to monitor.

Firefox is not giving any issue. the only external monitor i have is a 240Hz fullHD one. Tried with hdmi getting 1080p@120Hz, no issues. I don't have a usb-c->HDMI to try. By the way I don't see any issue with the CPU/RAM utilization.

I'm consideirng undervolting my CPU to bring the temps down, which I guess will fix some of the fan issues.

Does anyone know what Power Limit Throttling is? Before I went ahead with undervolting, I ran a stress test and I am getting Power Limit Throttling. Here is the link to my new post:

X1-Carbon-Power-Limit-Throttling

From what I know, 8th gen U processors are 15 W. However, turbo boost are set at 25W with Short Power Boost at 44W. I want to disable this or bring this down but it seems like Turbo Boost Technology is locked  on Enabled. I can't disable it.
