my laptop's lid is a little broken and when i put it in it's bag it'll be open while i'm handling it and then it get's out of the suspend mode, how can i change what opening the lid does, i only found how to change what closing the lid does in Power Manager, but there was no option to control what opening the lid does :D
I can't comment, but I think this can qualify as an answer. I'm almost 100% sure that the BIOS controls this function, and not the operating system. You can look in your BIOS settings, but it's doubtful there will be something to disable this.
You can try edit /etc/systemd/logind.conf. Set the option to ignore the lid switch instead of suspend.
loose the
#
sign. Then restart.
