Suspend/Hibernation Functions
Precautions for Using the Suspend or Hibernation Function
Save all data before powering off your computer.
When restarting from or shutting down to the suspend or hibernation mode, do not
touch the touch pad (or move the mouse (serial or PS/2 type) if one is connected).
These devices may fail to operate, you will then need to restart your computer using
the keyboard.
In addition, when restarting from the hibernation mode, do not use the touch pad or
keyboard, or press any of the switches, until Windows completely resumes.
(After the resume processing screen is displayed, nothing will appear on the display
for about 15 seconds, but the Windows display will appear soon after that.)
Do not power off during the following periods (you may corrupt your data or file):
• While the MP indicator (
• While playing/recording audio files.
• While communications software is being used.
Do not use the suspend or hibernation function when using an operating system
other than the one that comes with your computer, the Setup Utility, or when experi-
encing static electricity or noise.
If you hold down on the Alt , Ctrl or Shift
hibernation mode, after resuming operation, you must press the same key. For ex-
ample, if you hold down on the
resuming, if you do not press the
typing.
Only when the computer locks up should the sleep switch be held more than four
seconds to power off the computer. Slide the power switch to power on and data not
previously saved will be lost.
In the suspend mode, power is consumed. If PC Cards (e.g., a modem card) are
inserted, more of that power is consumed. When all power has been consumed, all
data at suspend is lost since it is retained in memory. We therefore recommend
plugging in the AC adapter when using the suspend function.
Repeatedly using the suspend or hibernation function will use up a lot of the system
resources and the computer may not work properly. Shut down Windows ([Start]-
[Shut Down]) on a regular basis, i.e.approximately once a week, without using the
suspend or hibernation function. Doing so will restore the system resources.
If you are using a PC card, note that some cards may cease to function if the suspend
or hibernation function is used several times. When this occurs, immediately shut
down Windows without using the suspend or hibernation function.
Do not use the suspend or hibernation function during the following periods. The
suspend or hibernation function may not work, or the computer (or peripherals) may
fail to work properly.
• When a file in external devices such as a CD-ROM drive, external hard disk, or ATA
card is opened, the suspend or hibernation function may not work. In such cases,
close the file.
• When using SCSI cards, the computer may not work after entering the suspend or
hibernation mode. In such cases, restart the computer.
• LAN cards and modem cards etc. may not recover after entering the suspend or
hibernation mode. If this occurs, restart the computer.
When inserting one more CardBus type card with one already inserted, after enter-
ing the suspend or hibernation mode, the computer may not function properly.
When a USB device is connected, there are cases the suspend or hibernation func-
tion will not operate in a normal manner due to the USB device. In addition, a USB
device may have to be removed temporarily and the computer restarted in cases
where the computer is unable to start up properly.
When both [Turn off monitor] (in [Control Panel] - [Power Management] - [Power
Schemes]) and [Screen Saver] (in [Control Panel] - [Display] - [Screen Saver]) are
set, there are cases operations cannot resume in a normal manner from the suspend
or hibernation mode.
When the screensaver setting is active, do not enter the suspend or hibernation
mode while the [MS-DOS Prompt] is being displayed. There are cases operations
cannot resume in a normal manner.
When the computer resumes from the suspend/hibernation mode when MS-DOS is
running, the screen may become completely black. In such cases, press
Alt + Tab .
