HI TheSilentRaven,
Welcome to the HP Forums!
I would like to take a moment and thank you for using the forum, it is a great place to find answers. For you to have the best experience in the HP forum, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand if you close your notebook for a significant amount of time, you are unable to restart, but have to shutdown.
Here is a link to Resolving Problems with Sleep and Hibernate Modes (Windows 8) that I believe will help.
Please let me know if you would like further assistance.
