Computer doesn't turn off completely

DrKillPatient · 2011-08-02 01:47:09

My desktop doesn't actually turn itself off when I shut it down in Arch. Actually, every Linux distro that I've tried (mint/ubuntu/fedora/SUSE as far as I can recall) does this. I'll hit the off button in the GUI or do shutdown -h now in the terminal, and it reaches 'power down' and sits there with a blinking cursor. I suspect Arch isn't using my resources to as much of an extent as the other distros I've tried, but with the others I've been able to hear-- fairly clearly-- everything that's been whirring winding down to a halt. At this point I have to hold down the power button to turn the computer off. I suspect it's a problem with my hardware failing to receive the final "shut off the power" command, and that it's simultaneously not fixable but not really more than a petty annoyance, and won't damage anything. Am I wrong in either assumption?-- maybe the first and hopefully not the second.

Here's the output immediately after the entry "> POWER OFF", the result of executing "shutdown -h now":

Synchronizing SCSI cache
Stopping disk
Synchronizing SCSI cache
Stopping disk
PCI INT A disabled
PCI INT C disabled
wake-up capability enabled by ACPI
ACPI: Preparing to enter system sleep state S5
Disabling non-boot CPUs ...
Power down.

And it sticks there.

same thing, slightly different readout on my netbook. First, try 'sudo poweroff' and see if that makes a difference, though it probably won't. Is the harddrive still spinning when you get to POWER OFF?

Exactly the same thing here

Have you tried passing the P flag with shutdown

shutdown -hP now

Nope, that doesn't work either, just freezes after powering down disks

I suggest you go into your BIOS and play with the ACPI/APM/sleep settings.

I hear a distinctive 'wind-down' noise as it runs the shutdown process. In addition, it does say "synchronizing SCSI cache / stopping disk" twice, I assume it's shutting down my two HDs. Is that an effective way to determine it?

I see ACPI suspend state is set as S3 State. The other option is S1. Is that what I should be changing?

Ok, finally got this working over here; in my /boot/grub/menu.lst, I added pci=noacpi to the kernel line, then in my /etc/rc.local.shutdown (as referenced here: https://bbs.archlinux.org/viewtopic.php?id=122956) I added modprobe -r vboxdrv, shutdown and reboot work now

I had a similar issue after init scripts update, but with reboot. After inspecting rc.shutdown, I simply added full path to poweroff and reboot commands, as they were before:

if [[ $RUNLEVEL = 0 ]]; then
    printhl "${C_H2}POWER OFF"
    /sbin/poweroff -d -f -h -i                                                <-- here...
else
    printhl "${C_H2}REBOOTING"
    # if kexec is installed and a kernel is loaded, use it
    [[ -x $(type -P kexec) ]] && kexec -e &>/dev/null
    /sbin/reboot -d -f -i                                                     <-- ...and here
fi

Now everything's OK. Maybe it works for you, too.

actually, setting pci=noacpi makes usb devices not work, so thats a bad idea, but the computer does shut down..... *looks for an alternative*

Thanks bohoomil, but nope, that doesn't work here

Hi, I was having the same problem and this is what needed changing in my BIOS.
BIOS > Power Management Setup > Wake Up Event Setup > Resume by PCI or PCI-E Device: [Enabled]
Toggle that to disabled. At first I thought it might let xorg go to sleep while watching movies or something but everything appears to be okay.

Are you using a custom kernel?

In case anyone knows more about this issue, I'm running x86_64 2.6.33.9-rt31 and rt-patched nvidia 285.05.09-1. Other symptoms: can shut down properly after starting X but not directly from tty after login. I get that this is a thoroughly unsupported combination and the problem only appeared when I switched to this setup from the stock kernel and drivers in extra, but this indicates to me that the problem is with your graphics driver... maybe??
