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, or modem use.
Power Schemes
Different patterns of Notebook use determine the level of power management needed.
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: length of inactivity before the Notebook goes into Standby mode.
• Turn Off Monitor: length of inactivity before the screen times out and goes blank.
• Turn Off Hard Disks: length of inactivity before the hard drive goes into low-power
mode.
• Hibernate: length of inactivity before the Notebook goes into Hibernation 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.
