How To Use Hybrid Suspend In Ubuntu

using the hybrid suspend method from this article, the system initially enters suspend which is quick to resume and after the time you set, the system hibernates so it no longer uses any battery power. This is useful if for example you close the lid when you move from one room to another (between meetings, classrooms, etc.) and you need the system to resume quickly, but you also want to preserve battery power if you don't use it.
