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 touchscreen (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.
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 experiencing
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 stops operating or locks up should the power 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 may be 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.
Do not use the suspend or hibernation function during the following periods. The
suspend or hibernation function, or peripherals may not work.
• 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.
• SCSI cards may not recover after entering the suspend or hibernation mode. If this
occurs, restart the computer.
After a Windows 95 USB device driver has been installed, do not use the suspend or
hibernation function. If the suspend or hibernation mode is activated, the computer
may not function properly. Power off, then on, using the power switch to resume proper
operation.
If you want to use the suspend or hibernation function after the USB driver is installed,
disable the USB device function of the computer by following the procedure below.
