I'm repurposing and old Dell Latitude D830 laptop for a Nagios monitoring server at work. Works great until I close the lid.

Is there a way I can force this laptop not to suspend when I close the lid? I have already changed the settings in Ubuntu to do nothing when I close the lid, and this works if I keep a user logged into the laptop.

But if I want to run a headerless server and have people login via SSH and I close the lid it immediately suspends.

Any secrets?

As you have installed Ubuntu, you will have the default power saving settings enabled.

This might help you:

Thanks, turning acpi=off in grub did the trick. – ProfessionalAmateur Feb 27 '13 at 20:20
