Fix laptop waking up while lid is closed and heating up

[thebestlettuce]

I had this problem for a while where my laptop would start to heat up while closed, and realized its because it was being woken up while closed and running when it should be suspended. I managed to figure out it was because my bluetooth mouse was giving it input while rattlign around in my backpack and waking it up.

You can diagnose this by closing your laptop almost fully so that the screen shuts off but you can still see it. Move your mouse around and if your screen turns on you have your problem

This script uses an ACPI event for the screen closing to fix this issue. This is made for the ASUS Zenbook 14 but will probably work with minor changes to other laptops

Follow the instructions at the top to set it up

(i only kind of know what im doing so lmk if this doesnt work for you)

This contribution is appreciated. Often I suspend and forget to hit the switch on the mouse straight away and the machine wakes up again.
