Hello Everyone, I'm running Desktop Ubuntu 18.04.4 LTS on my laptop HP zbook 15 G4 and my trouble is that the system (?) is using 1 CPU basically at all times even after fresh reboot and unfortunately nothing is listed in htop or top to debug this issue further: More details about the system: BIOS Information: Version: P70 Ver. 01.29 Product Name: HP ZBook 15 G4 Processor Information: Version: Intel(R) Core(TM) i7-7820HQ CPU @ 2.90GHz Note: CPU is 4 physical cores with HT. Any ideas how to debug this/find out what is using the resources? Thank you all for any input in advance.
