this is my first time asking a question here and if anyone could help me solve it, I will be very grateful (I am quite beginner). I have Ubuntu 18.04 in my HP Pavilion Laptop 15-cw0002la with AMD Ryzen 5 processor. When I press the power off button or even in the terminal typping "sudo shutdown -r now", my laptop's screen is off, but the light is still on and it keeps running, then I need to press the power button for 5 seconds to turn the laptop off.

I have tried everything in the following web pages and still doesn't work. Ubuntu 18.04 stuck at shutdown https://unixmen.com/fix-shutdown-power-computer-ubuntu-14-04/

Specially changing

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

and to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic"

You have BIOS F.35.

There's a newer BIOS available, F.42, dated Dec 11, 2019, and can be downloaded here.

Note: Confirm that I've got the correct web page for your model #.

Note: Have good backups before updating the BIOS.

  • I have already installed the new BIOS on the windows dual boot side, but now when I enter to Ubuntu still can't power off, but now there is also no wifi or sound. Help :( – David xie li Jun 07 '20 at 21:56
  • @Davidxieli Did you undo the changes that you made /etc/default/grub and then sudo update-grub? Did you reset the BIOS and then check individual BIOS settings to assure that they're correct? – heynnema Jun 08 '20 at 00:16
  • I am going to ask it in a question apart, thanks a lot – David xie li Jun 08 '20 at 15:41
  • @Davidxieli Why not finish this question? Check the settings in my prior comment first. – heynnema Jun 08 '20 at 15:45
  • already checked, all good, the only problem left is that it doesn't detect the wifi, only ethernet works – David xie li Jun 08 '20 at 16:34
  • @Davidxieli Check to make sure that the wifi is enabled in the new BIOS, and enabled in the wifi network settings panel. Also edit your question and show me sudo lshw -C network and dkms status and cat /etc/network/interfaces and cat /etc/netplan/*.yaml. Does the computer properly shutdown now? – heynnema Jun 08 '20 at 16:43
  • Ok I am on it, and yes it properly shutdown now, but now there is also no sound again – David xie li Jun 08 '20 at 16:55
  • @Davidxieli Oh, you completely changed your question. Wrong thing to do. My answer is null now. Although, since it solved the original shutdown question, you should probably accept it by clicking on the checkmark icon that appears just to the left of my answer. Thanks. What version Ubuntu is this? – heynnema Jun 08 '20 at 17:10
