Toshiba laptop in dual boot restarts after shutting down Xubuntu

[Yannanael]

Hello,
I bought a new Toshiba Satellite C870-15J with Windows 7 installed.
Made a dual boot with Xubuntu 12.04.
When I shut down Xubuntu, the system seems to turn itself completely off, but after some seconds I hear a click, and the system reboots itself.
The same when I shut down via the terminal with "sudo shutdown -h now".
In the power manager I changed the value for the onn-off button to shut off, but still the same problem.
I also entered the bios and made sure every Wake-on-LAN-like-function is disabled.
In grub I changed GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="acpi=force quiet splash" as suggested in another thread. To no avail...
When I use the "Windows-side" and shut off, it stays off, which is why I think it can't be a hardware problem.
Can anybody help me? It is a new laptop and it's rather annoying it won't work as it should...
Thanks,
Yann

Does the PC shutdown correctly when you run the following sudo command:

sudo shutdown -h now

try

sudo shutdown -P now

I think that should shut it down properly. I doesn't answer the question as to why it is re-starting, but it might help you out until you find a proper solution.

Hi. I bought a Toshiba Satellite Pro C850 a week ago and have had the same issues & symptoms, also with a Win7 dual boot setup. I use regular Ubuntu 12.04 though, installed from a cd.

None of the commands mentioned above worked for me, and I also tried "sudo poweroff" with the same results. I also tried rebooting, then shutting down from the login screen, but nope. I also tried a few shutdown-timer applications, with the same result - a reboot, not a shutdown.

I'm a newb & don't want to muscle in on someone else's thread, but if there's any way I can help to find a solution, please let me know. Thanks!

What happens when you run the following commands:

sudo vi /etc/default/grub

set

GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash"

then

sudo update-grub

What happens when you run the following commands:

The problem persists for me. Cheers.

Thanks for the tips, but they don't resolve the problem... Neither the "shutdown -P now" nor the
GRUB_CMDLINE_LINUX_DEFAULT="acpi=noirq quiet splash"The only way to shut down completely is waiting till the restart and then hitting the on-off button again... A way I don't really like.

Same problem here.

Bought and Acer Aspire v5-531g. Installed ubuntu 12.04 LTS next to windows 7. When I shut down ubuntu, my laptop shuts down, and a few seconds later boots up again. I can only properly shut down the laptop when i shut down through windows.

Reading that the above option hasnt worked for anyone, I havent tried it yet.

Let's go a different route as my wife's PC was having a similar issue in which it would not reboot nor shutdown. How I fixed it was as follows:

Type in terminal:

1. sudo gedit /etc/default/grub

2. Find the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

  3. Change this to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

4. Save the file and close the file.  5. Finally, in terminal: sudo update-grub

Let me know if this works for you.
