Different patterns of Notebook use determine the level of power management needed.
These power management levels can be initiated based on the amount of time passed
since the last system activity. System activity examples include keyboard strokes or mouse
movement, DVD/CD playback (while under program control that monitors Standby), and
modem use.
Power Schemes
You may select different settings or Power Schemes through Power Management
from the Control Panel. The default Power Schemes are Home/Office Desk,
Portable/Laptop, and Always On. The settings can 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
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.
