ubuntu not restarting or turning off

Lately I have been getting tired of my operating system just not wanting to reboot or sometimes not turning off. This happens in my version off ubuntu due a problem with the energy management. The way to solve this is changing the boot parameters for the operating system. So you will need to follow the next steps: 1. Edit the grub settings file (if you use nano as at the end do CTRL+O to save CTRL+X to close)

sudo nano /etc/default/grub
  1. Eddit the next line to look similar to the next one. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force reboot=pci"
  2. Call the command line to update the grub (os selector for operating system) sudo update-grub first reboot this will not make any difference but after your first reboot as the computer will boot with the new parameters this should solve the issue.

Disclaimer: this works in my case, every installation in different hardware than the one in my computer could have different outcomes (that i cannot be held accountable for, so use at your discretion), including booting issues that you might solve by removing the previous parameters before booting Ubuntu from grub.
