As part of JMU’s ongoing commitment to environmental stewardship and in compliance with Executive Order 82, the university has adopted Policy 1704-Energy Use. To assist with reducing power use on computers, instructions are listed below by operating system
Placing your computer in a low-power mode when not in use dramatically reduces the amount of energy your computer uses.
General information about low-power modes
Sleep or Standby: The state of your computer is saved in random access memory (RAM) and the computer enters a low-power mode.
Pros: Takes less time for your computer to return to an active state
Cons: In the event of a power outage, you may lose work in any unsaved documents
Hibernate: The state of your computer is saved to disk and the computer enters a low-power mode.
Pros: Because it writes your computer's "state" to disk, it is able to recover from a power outage.
Cons: Takes longer than sleep/standby to enter and exit low-power mode. Hibernate is not a default option on many systems, and may require administrative privileges to enable it.
The following screenshots illustrate entering Standby and Sleep modes. If Hibernation is enabled, it will also be a option on the menus.
