Resuming From Suspend-to-RAM Mode
Your computer resumes from the suspend-to-RAM mode in each of the following
cases:
• You press any key.
• The screen cover is opened.
• The built-in modem receives a call if Resume On Modem Ring in the Power
menu of the Setup Utility is set to Enabled (the built-in modem may not be
available in some countries).
• You slide the power switch when the item Power Switch Function is set as
Suspend/Resume in the Setup Utility.
Resuming From Suspend-to-Disk Mode
Your computer resumes from the suspend-to-disk mode when you slide the power
switch. The system restores the exact state as it was when entering the suspend
mode. If the computer enters the suspend mode because of low battery power,
however, you have to connect the computer to AC power first. Suspend-to-disk
mode is useful when you want to turn off the computer and reopen the same
windows after turning it on.
• If your battery becomes completely discharged while in suspend-to-
RAM mode, you will lose unsaved data and will need to reboot your
computer. Therefore, if you are planning to leave your computer
suspended for long periods of time, Dell recommends using suspend-
to-disk mode.
• When the system enters or resumes from the suspend-to-disk mode,
you can see some flicker on the display. This is not a malfunction.
• If sufficient battery power does not remain, your computer will not
resume from the suspend-to-disk mode. To resume it from the suspend-
to-disk mode, connect the computer to AC power.
• If a PC card does not work properly after your computer resumes from
the suspend-to-disk mode, restart the computer.
When entering or resuming from a suspend mode, be sure to observe the
following precautions. Otherwise, the computer may not operate
correctly after it has resumed from the suspend mode.
• Do not turn off the computer when the system is suspended to RAM.
The RAM contents will be lost.
• Do not operate the keyboard, glide pad or mouse while the system is
entering or resuming from a suspend mode.
