system restart automatically ?

[choisumpapa 0]

2 Questions :

 

1. I wonder why the system would restart automatically after shutting down. Is it normal behaviour ?

 

2. How can I turn the screen off when I am not using the laptop or hibernate the system.

 

Thank you for your help for a newbie.

Which OS are you using? I've ever got this problem with Win XP.

I've installed the Mandrake 10.1 recently in my old portable. It just keep self restarting at night.

 

Strange???!!!

Problem with the PSU? Did you check the logs?

Do you mean it keeps re-booting (will not totally shutdown), or starting up after doing a complete shutdown (the unit goes totally of then restarts on it's own later on)? If the system never shuts down properly, but just keeps rebooting, this is either an apm/acpi issue or hardware problem.

 

What laptop is this and how much ram in the system?

 

You can try changing the line in Grub from acpi=ht to acpi=no.

experiment with acpi and apm kernel parameters.
