double-tapping

Two quick taps, but on the second tap leaving your finger down (applying pressure) and moving it on the work surface.

While holding down the button, moving your finger on the work surface.

NOTE

Besides the above operations, operations such as Zoom and Pan are possible by allocating these functions to the buttons and/or pad. For more details, refer to [Mouse Properties]*.

* Windows 2000 : In [Control Panel] - [Mouse].

Windows XP : In [Control Panel] - [Printers and Other Hardware] - [Mouse].

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.

Touch Pad

Handling the Touch Pad

Do not place any object on the work surface or press down forcefully with sharppointed objects (e.g. nails) or hard objects that can leave marks (e.g. pencils and ball point pens). 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.

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 want to immediately start up and continue an application after shutting down your computer, you can do so by using either the standby or hibernation function.

Differences between the standby and hibernation functions

Function Where data is saved to Speed Requires power supply

Standby Memory Fast Yes (if power is cut, all data is lost) function

Hibernation Hard disk Somewhat Power is not required to maintain data function slow

NOTE

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. If the standby or hibernation function is used repeatedly, the computer may not work properly. To stabilize computer operations, we recommend shutting 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, make the setting below in advance. (Enabled in factory preset.)

Fn key combinations ( page 3) Using the power switch ( page 11) From the shut down screen:

• Standby

Windows 2000 : In [Start] - [Shut Down], select [Stand by]. Windows XP : In [start] - [Turn Off Computer], select [Stand By].

• Hibernation

Windows 2000 : In [Start] - [Shut Down], select [Hibernate]. Windows XP : In [start] - [Turn Off Computer], press and hold Shift , then

select [Hibernate].

Setting for using the hibernation mode

Windows 2000

Select [Start] - [Settings] - [Control Panel] - [Power Options].

In [Hibernate], add the check mark for [Enable hibernate support] and select [OK].

Windows XP

Select [start] - [Control Panel] - [Performance and Maintenance] - [Power Options].

In [Hibernate], add the check mark for [Enable hibernation] and select [OK].

Precautions

Before entering the standby or hibernation mode

Be sure to save all data. When a file in an external device such as a CD drive, external hard disk, or ATA card is opened, close the file. 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:

Windows 2000

Set the password in [Start] - [Control Panel] - [Users and Passwords].

Add the check mark for [Prompt for password when computer goes off standby] in [Control Panel] - [Power Options] - [Advanced].

Windows XP

Select the account to change in [Control Panel] - [User Accounts].

Set the password.

Add the check mark for [Prompt for password when computer resumes from standby] in [start] - [Control Panel] - [Performance and Maintenance] - [Power

Options] - [Advanced]. 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.

• When the floppy disk drive indicator ( ), hard disk drive indicator ( ), CD drive

indicator ( ) or access lamp on the CD drive is on ( page 6).

• When playing/recording audio files and displaying images (such as MPEG files).

• When using the communications software and the network function.

• When using LAN port (cards), SCSI cards and modem port (cards) etc. (If these

cards fail to work properly, restart the computer.)

When entering the standby or hibernation mode

Standby mode: until the power indicator blinks green Hibernation mode: until the power indicator goes off

Avoid the following:

• Using 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.

In standby or hibernation mode

Do not insert or remove peripherals; abnormal operation may result. 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.

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.

Four Important Points

POINT POINT

Be sure to charge your battery before and after use.

To get the maximum use of your battery, set the power man-

agement mode.

POINT

Check to see that you have your AC adaptor with you before

leaving your home or office. Purchasing a spare battery (CF-VZSU18/CF-VZSU18A) is

highly recommended.
