and when the system is idle. This function is transparent to the user. APM
also provides occasional screen messages about the battery while in the
Windows environment (for example, low power condition).
Power Management Settings
You can select power conservation settings through Computer Setup, Power
Management, or by pressing the Fn + F7 hotkeys to maximize power for
specific requirements. These settings control the power conservation rate
and the timeout values for various system components. A timeout is
specified period of system or component inactivity. After this period, the
system or component (for example, the hard drive) is shut down to conserve
power until it is accessed again.
If the power conservation rate and timeouts are not selected, the computer
uses the default settings listed in Table 1-3.
