Restart Toshiba Equium

I have installed openSUSE 11.1 on my Toshiba Equium A60.

If I ask openSUSE to shutdown (power off), the machine shuts down and powers off correctly.

If I ask openSUSE to restart, it shuts down and the screen goes completely blank. The power light remains on but it does not reboot.

Is there any way that I can get the restart function to work correctly?

Thanks.
