Power button

Asked by ddlaterreur

Hello,
I have a problem with my power button! Indeed, when I press on physical power button (hardware), the computer shutdown power supply. And when a shutdown ubuntu (software) with "sudo shutdown -h now" the computer shutdown HD but not power supply.
It's a software problem because with windows and ubuntu 6.06 all works well.
I change features in Power Manager Panel but that change nothing.
So I want to configure my computer to shutdown my computer when a press on physical and software power button (shutdown all: HD and power supply correctly)
Someone can help me ?

if you run this command from a terminal (ctrl+alt+T (<11.04), from dash (unity only) or from application menu(gnome))

watch ' dmesg | tail '

does anything appear up when you press the power button? You can press Ctrl+C to abort the command.

Nothing appear because the computer shut down immediately (there are no protocol to shutdown). It's like unplug the computer.
And if I click to shutdown button on GUI (or with this command: "sudo shutdown -h now"), the computer shut down with protocol hard disk but no all in the computer.
There is this message on the screen:

Ubuntu 10.10

I don't understand why the first and second dot are in red:
Unbuntu 10.10

Well, according to that, it appears to work just fine as far as the kernel is concerned. You might want to try loading your kernel without acpi using noacpi -- it could be an error in your BIOS' firmware. Though, I am guessing.
https://help.ubuntu.com/community/BootOptions

Alternatively try updating your BIOS to its latest version.

I try loading my kernel with change noacpi, but nothing change on my problem.
I saw my computer BIOS date is older than 2000 (1998 because it's old server) so I wrote in GRUB: acpi=force
Now, if I shutdown my computer (with this command: "sudo shutdown -h now"), all are okay; the computer shut down with protocol hard disk and power supply.
But there is one problem :S : When I press the physical power button nothing happens !

All my problems are solved. I used acpi=force and power manager app.
