Preventing laptop wake up when opening the lid on linux

reno_queen

My laptop is broken and the lid does not lock. So I want it not to wake up when the lid is open. I use ubuntu, but gnome-power-preferences does not have any option like that (only to close the lid). Is there any way to do this? I'm afraid next time it opens on the case it will get burned.
