44 Setting Up and Using Your Computer
Dell has added a fourth, Dell-Recommended mode that sets power
management to the most typical settings for the majority of our customers.
This is the active Power Plan.
Standby Mode
Standby mode is the default "off" state for Windows Vista. Standby mode
conserves power by turning off the display and the hard drive after a time-out.
When the computer exits from standby mode, it returns to the operating
state it was in before it entered standby mode.
To set standby mode to automatically activate after a defined period of inactivity:
1
Click
Start
and click
Control Pane
l.
2
Click
System and Maintenance
.
3
Under
System and Maintenance
, click
Power Options
.
The next dialog box will show three power plans - the top option is
Dell Recommended - this is the currently active plan.
There is also a show additional plans arrow underneath the three power
plans. You can have many power plans, but only three are displayed and the
top one is the active plan.
To immediately activate standby mode without a period of inactivity, click
Start , and then click the off button icon. Windows Vista sets Standby as
the default off state.
To exit from standby mode, press a key on the keyboard or move the mouse.
NOTICE: If your computer loses power while in standby mode, it may lose data.
Windows Vista has a new feature called Hybrid Sleep mode - this saves the data into a
file and also puts the system into standby. If you lose power, the system retains your data
on the hard drive and resumes to the same state you left it. Go to Help and Support and
search for Hybrid Sleep for further information. Hybrid Sleep provides fast wake if the
system is in standby, but also keeps your data safe by storing it to the hard drive.
Hibernate Mode
Hibernate mode conserves power by copying system data to a reserved area on
the hard drive and then completely turning off the computer. When the
computer exits from hibernate mode, the desktop is restored to the state it
was in before it entered hibernate mode. Windows Vista may mask Hibernate
from the user if Hybrid Sleep is enabled. See Help and Support for further
information - search for Hibernate.
