As has been mentioned previously your machine is probably old enough that it uses the older APM instructions for power management. You can disable the newer ACPI at boot time. You have two options: 1) do a one-time edit of the kernel line from the GRUB menu at bootup 2) edit the /boot/grub/menu.lst and then reboot I think the first way is likely easier for you. Here is a summary of how to do this: 1) Reboot. 2) At the initial GRUB boot screen, hit <ESC> to get to the grub menu. 3) Move the cursor highlight to the GRUB entry for the kernel you want to boot. 4) Hit the "e" key to go into edit mode. 5) Move the cursor down to the line with the kernel= in it. 6) Add the following two options to the end of the kernel line: acpi=off pci=noacpi 7) Hit <return> after adding the options to get back to the grub menu. 8) Hit the "b" key to reboot your computer with your edited changes. If it shuts down properly now then you can add these options permanently to your /boot/grub/menu.lst file.

I get on Reboot: Computer Memory Checking mode, or, Computer diagnostics Then: Starting Up..... 17179569.184000 ACPI: Unable to locate RSDP Then after a half minute: *Activating swap *Checking File system Etc. etc. After my session, when I go to Shut Down: ----- System is shutting down, please wait ... --- [ 452.715654] System halted. - (flashing hyphen) And the computer is still running...... At this point, in order to power down, I hit the Power Button. So, I guess that will have to be the way, when I go to use the machine for Xubuntu ... </div> -- ubuntu-ca mailing list <a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:ubuntu-ca@lists.ubuntu.com">ubuntu-ca@lists.ubuntu.com</a> <a onclick="return top.js.OpenExtLink(window,event,this)" href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-ca" target="_blank"> https://lists.ubuntu.com/mailman/listinfo/ubuntu-ca</a> </blockquote></div> -- Firefox (<a href="http://www.getfirefox.com">www.getfirefox.com</a>) -- A browser you can trust
