confuso

For me it also doesn't work well on X1C7, but it's looks more like it is easily overheating. If I have a core on 100%, within seconds the temperature rises...

Thanks a lot. I downloaded, unfortunately "fwupdmgr install ...Lenovo-ThinkPad-X1Carbon7th-X1Yoga4th-ECFirmware-1.10.cab" gave me a "no supported devices found" back. Do I have to take care with using fwupdmgr to update it?
