Power 3-15
Suspend-to-Disk Mode
In suspend-to-disk mode, power shuts off. The notebook saves all system
status information onto the hard disk (in a file created by Sleep Manager)
before entering suspend-to-disk mode. The next time you open the
notebook, it restores this information from the hard disk and resumes from
where you last left off.
Suspend-to-Disk Mode Conditions
For the notebook to enter suspend-to-disk mode, all of the following
conditions should exist:
• When Lid is Closed parameter is set to [Suspend To Disk]
• The suspend-to-disk file created by Sleep Manager is present and valid
• The Resume on Modem Ring and Resume on Schedule parameters
are disabled. See sections 6.5.5 and 6.5.6.
Entering and Leaving Suspend-to-Disk Mode
With the suspend-to-disk conditions satisfied, there are four ways to enter
suspend-to-disk mode:
• Closing the display
• Battery fail condition occurs without a powered AC adapter connected
and Suspend to Disk on Critical Battery is set to [Enabled].
• When battery is low while the notebook is in suspend-to-memory
mode, the notebook wakes up and performs a suspend-to-disk
operation to prevent data loss.
To leave suspend-to-disk mode, open the display. Make sure a charged
battery pack is installed and/or a powered AC adapter is connected before
you open the display.
Validating the Suspend-to-Disk File
To check if the suspend-to-disk file is present and valid, rest your cursor on
the Sleep Manager icon on the taskbar to show the status. See section 5.2
