Power Settings
Power management modes can be initiated based on the amount of time passed since the last
system activity. System activity includes keyboard strokes, mouse movement, CD/DVD playback,
and modem usage.
Power Schemes
Different patterns of Notebook use determine the level of power management needed. The Power
management settings can be selected using several predefined Power Schemes. To access these
options, select Power Management on the Control Panel, then click the Power Schemes tab. The
default Power Schemes are Home/Office Desk, Portable/Laptop, and Always On. Power Schemes can
also be customized by changing the following options:
•
System Standby: the length of inactivity before the Notebook goes into Standby mode
•
Turn Off Monitor: the length of inactivity before the screen times out and goes blank
•
Turn Off Hard Disks: the length of inactivity before the hard drive goes into low-power
mode
Important: The setting for the Hard Disk must be less than or equal to the setting for
the System. If the Notebook is on a network, Compaq recommends that System
Standby be set to Never.
The following table shows the default settings for each Power Scheme.
