Turning off laptop monitor when the lid is closed?

[BenST]

Hi,

I have a Dell Inspiron 6000 laptop. In the power saving tab there are options to suspend / hibernate the computer when the lid is closed but ideally I would like an option to blank / turn off the monitor so that I can leave the laptop running whilst closed.

Does anyone know how to enable such an option? Thanks.

the screen should automatically go off when the lid is closed, there is usually a catch on the base of the laptop than touches a contact and turns the screen off, tis in my case anyway.

I know this and there is no visible switch. I've given up, there is no proper way to make this screen blank when the lid is closed. How bizarre.
