Getting Started
To disconnect your computer completely from AC power, unplug the AC adapter.
Make sure that the AC outlet is easily accessible.
If you do not use your computer for a long period of time, place the computer into Hibernate mode. See Using Hibernate Mode (page 82). This power
saving mode saves the time of shutting down or resuming.
The plug attachment can be detached and reattached with the plug turned upside down.
