Ubuntu – Ubuntu 18.10 CPU1 always around 100% despite no programs are running

18.10cpucpu loadinteloverheating

I'm new user who transitioned from Windows and I have this nasty problem
since I installed Ubuntu 18.10 on my HP ProBook 450 with I3-6100 with 2 core and 4 threads my CPU 1 is around 100% and CPU 2,3,4 are <10%. My laptop is overheating and fan is always on…
Unfortunately haven't found anyone with this kind of problem.
This is Htop picture of no programs running:

I've seen people suggest running update and upgrade, but haven't helped me.
As far as I checked all drivers are up to date.

Update 1:

We may have a HP BIOS/ACPI problem.

  1. Lets check the BIOS first...

In terminal type sudo dmidecode -s bios-version and note the output.

Compare the output with this...

enter image description here

If your BIOS is older, go to here to download the new BIOS.

Note: backup your important data before installing the new BIOS.

Install the new BIOS.

Monitor the top CPU processes, looking for kacpid, using the top command in the terminal.

  1. Kernel ACPI patch...

If you tried these steps before I had completed the instructions, then do this command:

sudo rm -i /etc/default/xxxx # delete this unnecessary file

Then continue...

sudo -H gedit /etc/default/grub # edit grub defaults

Find and change:

"quiet splash"

to:

"quiet splash acpi=strict"

sudo update-grub # update grub

sudo update-initramfs -c -k $(uname -r) # update initramfs

reboot # reboot the computer

Monitor the top CPU processes, looking for kacpid, using the top command in the terminal.

Update #1:

To solve the current boot problem...

If you have ANY problems with this procedure, contact me immediately.

  • at the GRUB menu...

  • hit the e key to enter edit mode

  • using the arrow keys, find "quiet splash pnpacpi=off" and change it to "quiet splash"

  • hit the control+x, or F10 key to continue to boot

  • once booted, repeat Step #2 in my answer, and change "quiet splash pnpacpi=off" back to just "quiet splash", and do the follow-on commands

  • you should be able to reboot normally

Update #2:
