Setting Up and Using Your Computer
25
Standby Mode
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 the Start button and click Control Panel.
2 Under Pick a category, click Performance and Maintenance.
3 Under or pick a Control Panel icon, click Power Options.
To immediately activate standby mode without a period of inactivity, click the Start button, click
Turn Off Computer, and then click Stand by.
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.
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.
To activate hibernate mode:
1 Click the Start button and click Control Panel.
2 Under Pick a category, click Performance and Maintenance.
3 Under or pick a Control Panel icon, click Power Options.
4 Define your hibernate settings on the Power Schemes tab, Advanced tab, and Hibernate tab.
To exit from hibernate mode, press the power button. The computer may take a short time to exit
from hibernate mode. Pressing a key on the keyboard or moving the mouse does not bring the
computer out of hibernation, because the keyboard and the mouse do not function when the
computer is in hibernate mode.
Because hibernate mode requires a special file on your hard drive with enough disk space to store
the contents of the computer memory, Dell creates an appropriately sized hibernate mode file
before shipping the computer to you. If the computer’s hard drive becomes corrupted,
Windows XP recreates the hibernate file automatically.
Power Options Properties
Define your standby mode settings, hibernate mode settings, and other power settings in the Power
Options Properties window.
To access the Power Options Properties window:
1 Click the Start button and click Control Panel.
2 Under Pick a category, click Performance and Maintenance.
