[Bug 500301] Re: Computer won't real power off

[Charlie Kravetz]

Since this workaround is working for you, you can edit the grub
configuration file and add the arguments there. To do so:

1. In a terminal:
    cd /etc/default <ENTER>
2. sudo mousepad /etc/default/grub <ENTER>
    if you are using Ubuntu, use 'gedit' instead of 'mousepad'
3. down arrow to the line that reads:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
4. Add the argument to this line:
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
5. Save the file
6. In the terminal, run the command to update the grub menu:
    sudo update-grub <ENTER>
7. cd <ENTER>

Now when starting the computer, 'acpi=force' will be automatically used
for each grub menu item. When Grub is updated in the system updates,
this will need to be added again.


** Description changed:

  I have a old(about 3 years) computer, and installed Xubuntu 9.10 and Ubuntu 10.04. When I shutdown my computer, both Xubuntu and Ubuntu can't real power off my computer, and remained some text: "system halted". I must manually power off my computer every day.
  Have a look please.
  
  My kernel is: 2.6.32-9-generic(Ubuntu) and 2.6.31-14-generic(Xubuntu).
  
  Тhanks a lot!
