I'm using dual screen mode on a Lifebook a531 with external monitor at hdmi.

When I close the lid my laptop didn't go to suspend. Only both screens are blanking. Moving of mouse pointer wakes up an external monitor. But "suspend" from desktop menu works normally, system goes to suspend.

Is there any way to change it?

I'm having exactly the same problem, detaching the second monitor will allow the computer into sleep mode. I tried hybernating but that won't work at all (laptop will simply shut down).

Any ideas?

Thanx for any and all replies.
