z The operations of Scroll, Pan or Zoom will differ depending on the application. There
are cases the touch pad will not support these operations even with an application
that supports the functions.
Handling the touch pad
12
z By design the touch pad is to be used with a finger tip only. Do not place any object on the
work surface or press down forcefully with sharp-pointed objects (e.g., nails) or hard
objects that can leave marks (e.g., pencils and ball point pens).
z Try to avoid having any harmful substances such as oil, come in contact with the touch
pad. The cursor may not work properly in such cases.
z When the touch pad becomes dirty:
Wipe to remove dirt by using a dry soft cloth such as gauze or a soft cloth first applied with
detergent diluted with water and then thoroughly wrung.
Do not use benzene or thinner, or rubbing alcohol. Doing so may adversely affect the
surface, e.g., discoloration. In addition, do not use commercially-available household
cleaners and cosmetics, as they may contain components harmful to the surface.
Standby/Hibernation Functions
Starting Up Your Computer Quickly
If you use the standby or hibernation function, you can shut down the computer without
closing programs and documents. Upon restarting your computer from either the standby or
hibernation mode, you can immediately continue working in all programs, or documents that
were open at the time the computer was placed into standby or hibernation mode.

NOTE
z We recommend plugging in the AC adaptor if the standby function is to be used for a
long period of time. If the AC adaptor cannot be connected, we recommend that
hibernation mode be used instead of the standby mode.
z If the standby or hibernation function is used repeatedly, the computer may not work
properly. To stabilize computer operations, shut down Windows on a regular basis
(about once a week) without using the standby or hibernation function.
Entering the Standby or Hibernation Mode
Use any of the following methods to enter the standby or hibernation mode.
To use the hibernation mode, set [Power Options] in advance (Î page 14).
(Enabled in factory preset.)
z Using Fn key combinations (Î page 5)
z Using the power switch (Î page 16)
z Using the display (Î page 17)

Setting for Using the Hibernation Mode
At the time of purchase, the computer is set so that hibernation mode can be used.

2 In [Hibernate], add the check mark for [Enable hibernation] and select
[OK].
Precautions
Shift
, then select [Hibernate].
14
Before entering the standby or hibernation mode
z Be sure to save all data.
z When a file in an external device such as an external CD/DVD drive, hard disk, or ATA
card is opened, close the file.
z Even when a password has been set in the Setup Utility, [Enter Password] does not
appear when the computer resumes from the standby or hibernation mode. If you want to
use the security function when using the standby or hibernation mode, use the Windows
password as follows:
A Select the account to change in [start] - [Control Panel] - [User Accounts].
B Set the password.
C Add the check mark for [Prompt for password when computer resumes from
standby] in [start] - [Control Panel] - [Performance and Maintenance] - [Power
Options] - [Advanced].
z Do not enter either the standby or hibernation mode under the following conditions. You
may corrupt your data or file, the standby or hibernation function may not work, or the
computer (or peripherals) may fail to work properly.
Standby/Hibernation Functions
• When the MP indicator or hard disk drive indicator is on (Î page 9).
• When playing/recording audio files and displaying images (such as MPEG files).
• When playing a DVD-Video.
• When writing to a CD-R/RW disc.
• When using communications software or the network function.
• When using PC Cards.
(If these cards fail to work properly, restart the computer.)
z The computer cannot enter standby or hibernation mode under the following condition.
• When B’s Recorder/B’s CLiP have been installed:
If a disc formatted with B’s CLiP is inserted into the CD/DVD drive (while is displayed
on the taskbar), eject the disc in advance.(Î page 53)
When entering the standby or hibernation mode
Standby mode: until the power indicator blinks green
Hibernation mode: until the power indicator goes off
z Avoid the following:
• Touching the keyboard, touch pad, or power switch.
• Using external mouse or other peripheral devices.
• Connecting or disconnecting the AC adaptor.
• Closing or opening the display.
z It may take one or two minutes to enter standby or hibernation mode.
15
In standby or hibernation mode
z Do not insert or remove peripherals; abnormal operation may result.
z In standby mode, power is consumed. If PC Cards are inserted, more of that power is
consumed. When all power has been consumed, all data saved at standby is lost since it
is retained in memory. We therefore recommend plugging in the AC adaptor when using
the standby function.

When you do not want the data on the hard disk to be read/

When the Hard Disk Lock is set to [Enable], it is impossible to read/write data from/to the
hard disk when the hard disk is inserted in a different computer, since a password is also set
for the hard disk. When the hard disk is returned to the original computer, you can read and
write data as before. In this case, however, make the settings in the Setup Utility exactly the
same as they were before the hard disk was removed.
It is possible to set the Hard Disk Lock even if [Password on boot] is set to [Disable], but we
recommend that [Password on boot] be set to [Enable] for security reasons.
(Note that this Hard Disk Lock does not guarantee complete protection of data.)

Computing on the Road
Saving Power
One of the main features of notebook-type computers is that you have the power of
computing away from your home or office. In the following, information is provided on how to
maximize use of the battery pack which is necessary for such computing.
z Four Important Points
• POINT 1
Be sure to charge your battery before and after use.
• POINT 2
To get the maximum use of your battery, set the power management mode.
• POINT 3
Check to see that you have your AC adaptor with you before leaving your home or
office.
Purchasing a spare battery (CF-VZSU29) or the second battery pack is highly
recommended.
• POINT 4
Always watch your battery level!
