Operating Basics
Heat dispersal
To protect from overheating, the CPU has an internal temperature sensor. If 
the computer’s internal temperature rises to a certain level, the cooling fan 
is turned on or the processing speed is lowered. You can select whether to 
control the CPU temperature by turning on the fan first, then if necessary, 
lowering the CPU speed. Or, by lowering the CPU speed first, then if 
necessary, turning on the fan. These functions are controlled within the 
Power Options.
When the CPU temperature falls to a normal range, the fan is turned off 
and the CPU operation returns to standard speed.
Using the Hard Disk Drive (HDD) Protection
This computer has a function for reducing the risk of damage on the hard 
disk drive.
Using an acceleration sensor built into the computer, TOSHIBA HDD 
Protection detects vibration shocks and similar signs of movement of the 
computer, and automatically moves the Hard Disk Drive head to a safe 
position to reduce the risk of damage that could be caused by head-to-disk 
contact.
When vibration is detected, a message will be displayed on the screen, and 
the icon in the Taskbar notification area will changed to the protection state. 
This message is displayed until the OK button is pressed or 30 seconds 
pass. When vibration subsides, the icon returns to the normal state.
Taskbar icon
If the CPU temperature reaches an unacceptably high level with either 
setting, the system automatically shuts down to prevent damage. Data in 
memory will be lost.
The TOSHIBA HDD Protection function does not guarantee that the hard 
disk drive will not be damaged.

TOSHIBA HDD Protection Properties
You can change the TOSHIBA HDD Protection settings by using the 
TOSHIBA HDD Protection window. To open the window, click Start  All 
Programs  TOSHIBA  Utilities  HDD Protection Settings. The 
window can also be started from the icon on the Taskbar or from the 
Control Panel.
HDD Protection
You can choose whether to enable or disable TOSHIBA HDD Protection.
Detection Level
This function can be set to four levels. The sensitivity levels in which 
vibrations, impacts and their similar signs are detected can be set to OFF, 
1, 2 and 3 in ascending order. Level 3 is recommended for better protection 
of the computer. However, when the computer is used in a mobile 
environment or in other unstable conditions, setting the detection level to 3 
could result in frequent execution of TOSHIBA HDD Protection, which will 
slow Hard Disk Drive reading and writing. Set a lower detection level when 
the speed of Hard Disk Drive reading and writing is a priority.
Different detection levels can be set depending on whether the computer is 
used as handheld or mobile usages, or whether it is used in a stable 
environment such as on a table in the workplace or at home. By setting 
different detection levels for the computer depending on whether it runs 
with the AC power (desktop) or with batteries (handheld or mobile usage), 
the detection level automatically switches according to the power 
connection mode.
3D Viewer
This feature displays a 3D object on the screen which moves in according 
to tilting or vibration of the computer.
When the TOSHIBA HDD Protection detects computer vibration the Hard 
Disk Drive head is parked and the 3D object disk rotation will stop. When 
the head is un-parked the disk will begin to rotate again.
The 3D Viewer can be started from the icon in the task tray.
■This 3D object virtually represents the Computer’s internal Hard Disk 
Drive. This representation may vary from the actual number of disks, 
disk rotation, head movement, part size, shape and direction.
■This feature may use a large amount of CPU and memory on some 
models. The computer may become slow or sluggish when attempting 
to run other applications while the 3D Viewer is displayed.
■Intensely shaking the computer or other subjecting it to strong impacts 
may cause damage to the computer.

The Keyboard
Chapter 5
The Keyboard
The computers keyboard layouts are compatible with a 104/105-key 
enhanced keyboard - by pressing some keys in combination, all of the 
104/105-key enhanced keyboard functions can be performed on the 
computer.
The number of keys available on your keyboard will depend on which 
country/region your computer is configured for, with keyboards being 
available for numerous languages.
In use there are six different types of keys, specifically typewriter keys, 
function keys, soft keys, Hot keys, Windows special keys and the keypad 
overlay.
Typewriter keys
The typewriter keys produce the upper-case and lower-case letters, 
numbers, punctuation marks, and special symbols that appear on the 
screen. However, there are some differences between using a typewriter 
and using a computer keyboard:
■Letters and numbers produced in computer text vary in width. Spaces, 
which are created by a space character may also vary depending on 
line justification and other factors.
■The lowercase l (el) and the number 1 (one), together with the 
uppercase O (oh) and the 0 (zero), are not interchangeable on 
computers as they are on a typewriter.
■The CAPS LOCK function key locks only the alphabetic characters into 
upper-case while the Shift Lock function on a typewriter places all keys 
in the shifted position.
■The SHIFT keys, the Ta b key, and the BACK SPACE key perform the 
same function as their typewriter counterparts but also have special 
computer functions.
Never remove the key caps on your keyboard. Doing so could cause 
damage to the parts under the key caps. 
						

							User’s Manual5-2
The Keyboard
Function keys: F1 … F12 
The function keys (not to be confused with the special FN key) are the 
twelve keys at the top of your keyboard - these keys function differently 
from other keys.
F1 through F12 are called function keys because they execute 
programmed functions when pressed and, when used in combination with 
the FN key, those keys marked with icons also execute specific functions 
on the computer. Please refer to the section, Soft keys: FN key 
combinations, in this chapter for further information, taking care to note that 
the function executed by individual keys will depend on the software you 
are using.
Soft keys: FN key combinations
The FN (function) is unique to TOSHIBA computers and is used in 
combination with other keys to form soft keys. Soft keys are key 
combinations that enable, disable or configure specific features.
Emulating keys on an enhanced keyboard
A 104-key enhanced keyboard layout
This computers keyboard is designed to provide all the features of the 104-
key enhanced keyboard.
Since the keyboard is smaller and has fewer keys, some of the enhanced 
keyboard functions must be simulated using two keys instead of one on the 
larger keyboard.
The FN key can be combined with the following keys to simulate functions 
similar to those of keys on the 104/105 key enhanced keyboard which are 
not on this computers keyboard.
Please note that some software may disable or interfere with soft-key 
operations, and that the soft-key settings are not restored when the 
computer returns from Standby Mode.
