Are you sure you need to? My laptop automatically switches of the screen when
the lid is closed.

Set the 'debug.acpi.resume_beep' sysctl(8) to 1 to make the speaker beep on
resume. That can help you debug problems. Setting 'hw.acpi.verbose' might also
help.
Some systems need the sysctl 'hw.acpi.reset_video' set to 1 to get it to
resume properly.
See acpi(4).
