Power Conservation Modes
The following power conservation modes are available for use on your computer:
l Standby mode
l Hibernate mode / save-to-disk suspend mode
Standby Mode
Standby mode turns off the display, stops the hard-disk drive, and turns off other internal devices so that the computer uses less battery power. When the computer resumes
operation from standby mode, the desktop is restored exactly as it was before the computer entered standby mode.
NOTICE: If you lose AC or battery power while in the standby mode, you may experience data loss.
NOTICE: On computers using the Microsoft ® Windows NT ® operating system, data loss from RAM may occur if the battery discharges completely when the
computer is in standby mode.
For information on activating standby mode, refer to Activating Standby Mode .
Hibernate Mode/Save-to-Disk Suspend Mode
Save-to-disk suspend mode copies all system data to a reserved area on the hard-disk drive and then turns off all power to the computer. When you resume normal operation,
the same programs will be running and the same files will be open that were open before you activated this mode.
Place the computer in save-to-disk suspend mode if you do not intend to store the computer for longer than 40 days. Save-to-disk suspend mode preserves the configuration
information stored in
NVRAM . The reserve battery on the system board maintains this information, but it may run out of charge after 40 days.
Save-to-disk suspend mode helps preserve system data by quickly saving it onto the hard-disk drive if the computer is about to run out of battery power.
Some PC Cards may not operate correctly after exiting from save-to-disk suspend mode. If you encounter problems with a card, remove and replace it.
For information on activating save-to-disk suspend mode, refer to Activating Hibernate Mode/Save-to-Disk Suspend Mode .
Activating Standby Mode
To activate standby mode in the Microsoft Windows ® 98 or Windows NT operating system, see the following subsections. To resume normal operation from the standby
mode, press the power button or open the display cover.
Your computer automatically enters standby mode if the standby time-out setting of the selected power scheme expires.

l Click the Start button, click Shut Down, click Stand by, and then click OK.

NOTE: Save-to-disk suspend mode requires a special file on your hard-disk drive that sets aside enough disk space to store the contents of the
computer's memory. Dell creates an appropriately sized save-to-disk suspend file before shipping the computer to you. If you remove the file or if your
hard-disk drive becomes corrupted, you must recreate the file before you can again use save-to-disk suspend mode.
For instructions on creating the file, refer to "Save-to-Disk Suspend Utility" in Chapter 4 of the Reference and Troubleshooting Guide.
NOTES: Opening the display recovers the computer from standby mode only if you programmed the display-close button to put the computer into
standby mode (the default). For information on programming the display-close button, refer to Using Windows 98 to Conserve Battery Power or Using
Windows NT to Conserve Battery Power .
Pressing a keyboard key or moving the mouse will not bring the computer out of standby mode.
