system restart automatically ?

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.

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.
