techniques to conserve battery power. For example, it the display is
closed while operating the computer, it automatically enters Suspend
Mode and all tasks are stopped to save power, and their present
states are stored in the computer memory. Later, when the display is
opened, the computer automatically returns to Resume Mode and
restores the same states as when it entered Suspend Mode.
