Assuming you have some sort of PC (not a Mac), you will change it in grub.
I was going to point you to the grub HowTo
https://wiki.ubuntu.com/GrubHowto but to me that looks pretty
confusing. I'm not in front of that PC tonight (normally I use Ubuntu
on my Macs and they boot differently), but I'll try to remember well
enough to get you started. Oh and I should say now that grub is one of
the things I haven't learned very well because it's not what I usually
use.
First of all I'll tell you how to test it by editing the kernel
parameters temporarily. This will take effect ONLY once (nothing will
get saved):
1) When the machine is FIRST booting, watch for grub prompt (start the
PC and usually the screen will go black immediately after the PC
company's logo appears) RIGHT THEN press the Esc key on your keyboard
-- by default you have a very short time to do this. If you start
seeing the Ubuntu startup messages you missed it, so start over.
2) Once you get the grub menu up, you'll see all the kernels that are
installed (each listed twice, once each for normal and once each for
recovery mode). Leave the top one highlighted -- it's the one you
usually use.
3) I believe you press "e" to edit the parameters. (If I'm wrong, do
whatever it says on the bottom of the screen.)
4) Use the down-arrow key to move the highlight bar down to the line
that starts with the word "kernel" (and here I can't remember whether
you press "e" again or just press Return). Do whatever it says on the
bottom of the screen.
5) Add acpi=force to the end of the kernel line
6) Press return and you should see the edited line (now it's cut off
where it would go past the right side of the screen).
7) Press "b" to boot using the new parameter.
After the machine boots, see if the power works as you expected. If it
does, please add your information to bug 39499 --

------
To make it boot this way every time, after the machine has booted you
can edit the grub menu file /boot/grub/menu.lst -- here are the three
commands you can type in a terminal window to 1) switch to the grub
directory 2) make a backup copy and then 3) edit the menu file using
gedit:
cd /boot/grub/
sudo cp menu.lst menu.lst.old
sudo gedit menu.lst
-- look for the kernel line you edited before (it's way down in the
file after lots of comments).
Here's where I'm very unsure --I don't know whether at this point you
should run the update-grub command. I don't, and I lose the edited
kernel parameter every time there's a Dapper kernel update. To me this
is fine because I want to know whether the new version of the kernel
works right.
I hope I haven't led you astray... if anything of these directions
seem off, just write again and I'll check when I'm back at the office
where I have the PC to make sure.
