Troubleshooting
TOSHIBA designed the computer for durability. However, should problems
occur, following the procedures in this chapter can help to determine the
cause.
All readers should become familiar with this chapter. Knowing what might
go wrong can help prevent problems from occurring.
Problem solving process
Resolving problems will be much easier if you observe the following
guidelines:
■ Stop immediately when you recognize a problem exists. Further action
may result in data loss or damage. You may destroy valuable problemrelated information that can help solve the problem.
■ Observe what is happening. Write down what the system is doing and
what actions you performed immediately before the problem occurred.
If you have a printer attached, print a copy of the screen using PRTSC.
The questions and procedures offered in this chapter are meant as a guide,
they are not definitive problem solving techniques. Many problems can be
solved simply, but a few may require help from your dealer. If you find you
need to consult your dealer or others, be prepared to describe the problem
in as much detail as possible.
User’s Manual
9-1
Troubleshooting
Preliminary checklist
Consider the simplest solution first. The items in this checklist are easy to
fix and yet can cause what appears to be a serious problem.
■ Make sure you turn on all peripheral devices before you turn on the
computer. This includes your printer and any other external device you
are using.
■ Before you attach an external device, turn the computer off. When you
turn the computer back on it recognizes the new device.
■ Make sure all options are set properly in the setup program.
■ Check all cables. Are they correctly and firmly attached? Loose cables
can cause signal errors.
■ Inspect all connecting cables for loose wires and all connectors for
loose pins.
■ Check that your floppy disk or CD/DVD-ROM is correctly inserted and
that the floppy disk’s write protect tab is correctly set.
Make notes of your observations and keep them in a permanent error log.
This will help you describe your problems to your dealer. If a problem
recurs, the log will help you identify the problem faster.
Analyzing the problem
Sometimes the system gives clues that can help you identify why it is
malfunctioning. Keep the following questions in mind:
■ Which part of the system is not operating properly: keyboard, floppy
disk drives, hard disk drive, optical media drive, display. Each device
produces different symptoms.
■ Is the operating system configuration set properly? Check the
configuration options.
■ What appears on the display screen? Does it display any messages or
random characters? If you have a printer attached, print a copy of the
screen using PRTSC. Look up the messages in the software and
operating system documentation. Check that all connecting cables are
correctly and firmly attached. Loose cables can cause erroneous or
intermittent signals.
■ Do any indicators light? Which ones? What color are they? Do they stay
on or blink? Write down what you see.
■ Do you hear any beeps? How many? Are they long or short? Are they
high pitched or low? Is the computer making any unusual noises? Write
down what you hear.
Record your observations so you can describe them to your dealer.

Troubleshooting
Software
Hardware
The problems may be caused by your software or disk. If
you cannot load a software package, the media may be
damaged or the program might be corrupted. Try loading
another copy of the software.
If an error message appears while you are using a software
package, check the software documentation. These
documents usually include a problem solving section or a
summary of error messages.
Next, check any error messages in the OS documentation.
If you cannot find a software problem, check your
hardware. First run through the items in the preliminary
checklist above. If you still cannot correct the problem, try
to identify the source. The next section provides checklists
for individual components and peripherals.
Before using a peripheral device or application software that is not an
authorized Toshiba part or product, make sure the device or software can
be used with your PC. Use of incompatible devices may cause injury or
may damage your PC.

■ Discard this PC in accordance with ordinances or rules of local
regulations. For further information, contact your local government.
■ This PC contains rechargeable batteries. After repeated use, the
batteries will finally lose their ability to hold a charge and you will need
to replace them. Under certain applicable laws and regulation, it may be
illegal to dispose of old batteries by placing them in the trash.
■ Please be kind to our shared environment. Check with your local
government authority for details regarding where to recycle old
batteries or how to dispose of them properly. This product contains
mercury. Disposal of this material may be regulated due to
environmental considerations. For disposal, reuse or recycling
information, please contact your local government.
■ If your hard disk or other storage media contains sensitive data, you

from the media. These standard deletion procedures include:
■ Selecting Delete for a target file
■ Putting files in the Recycle Bin and emptying the Recycle Bin
■ Reformatting the media
■ Reinstalling an operating system from the recovery CD-ROM
The procedures above delete only the initial part of the data used for file
management. This makes the file invisible to the operating system, but

references are approximate and may vary depending on the specific
computer model - please refer to your PC documentation or visit the
Toshiba website at www.pcsupport.toshiba.com for details).
CPU performance may also vary from specifications due to design
configuration.
Under some conditions, your computer product may automatically shutdown. This is a normal protective feature designed to reduce the risk of lost
data or damage to the product when used outside recommended
conditions. To avoid risk of lost data, always make back-up copies of data
by periodically storing it on an external storage medium. For optimum
performance, use your computer product only under recommended
conditions. Read additional restrictions under “Environmental Conditions”
in your PC documentation. Contact Toshiba technical service and support,
refer to TOSHIBA support section in Chapter 9 Troubleshooting for more
information.
Copy Protection*3
Copy protection technology included in certain media may prevent or limit
recording or viewing of the media.
HDD Drive Capacity*4
1 Gigabyte (GB) means 1000 × 1000 × 1000 = 1,000,000,000 bytes using
powers of 10. The computer operating system, however, reports storage
capacity using powers of 2 for the definition of 1 GB = 1024 × 1024 × 1024
= 1,073,741,824 bytes, and therefore may show less storage capacity.
Available storage capacity will also be less if the product includes one or
more pre-installed operating systems, such as Microsoft Operating System
and/or pre-installed software applications, or media content. Actual
formatted capacity may vary.
Non-applicable Icons*5
Certain notebook chassis are designed to accommodate all possible
configurations for an entire product series. Your selected model may not
have all the features and specifications corresponding to all of the icons or
switches shown on the notebook chassis, unless you have selected all
those features.

Wireless LAN/Atheros*6
The transmission speed over the wireless LAN and the distance over which
wireless LAN can reach may vary depending on surrounding
electromagnetic environment, obstacles, access point design and
configuration, and client design and software/hardware configurations.
[54Mbps is the theoretical maximum speed under the IEEE802.11 (a/b/g)
standard.] The actual transmission speed will be lower than the theoretical
maximum speed.
To use the Atheros Super AGTM or Super GTM function, your client and
access point must support the corresponding feature. Performance of
these functions may vary depending on the format of data transmitted.
TV Tuner*7
TV Tuner will function only in the country where the computer was
purchased.
Images*8
All images are simulated for purposes of illustration.
LCD Brightness and Eye Stain*9
Your LCD display has a brightness approaching that of a TV device. We
recommend that you adjust the brightness of your LCD to a comfortable
level to prevent possible strain on your eyes.
Safety Use for TV Tuner*10
If you have to operate your PC during a thunderstorm and are connecting
the TV tuner to an outside antenna, you should operate your PC using AC
power mode. The AC adapter offers some protection against (but does not
entirely prevent) possible electric shock caused by lightning. For complete
protection, do not operate your PC during a thunderstorm.
Graphics Processor Unit ("GPU”)*11
Graphics processor unit ("GPU") performance may vary depending on
product model, design configuration, applications, power management
settings and features utilized. GPU performance is only optimized when
operating in AC power mode and may decrease considerably when
operating in battery power mode.

graphics system, applications utilized, system memory size and other
factors.
Battery Life Disclaimer*13
Battery life may vary considerably depending on product model,
configuration, applications, power management settings and features
utilized, as well as the natural performance variations produced by the
design of individual components. Published battery life numbers are
achieved on select models and configurations tested by Toshiba at the time
of publication. Recharge time varies depending on usage. Battery may not
charge while computer is consuming full power. After a period of time, the
battery will lose its ability to perform at maximum capacity and will need to
be replaced. This is normal for all batteries. To purchase a new battery

Display Controller and Modes
Display controller
The display controller interprets software commands into hardware
commands that turn particular pels on or off.
The display controller supports VGA, SVGA and XGA modes at internal
LCD display panel.
A high-resolution external monitor connected to the computer can display
up to 2048 horizontal and 1536 vertical pixels at up to 64K mode.
The display controller also controls the video mode, which uses industry
standard rules to govern the screen resolution and the maximum number of
colors that can be displayed on screen.
Software written for a given video mode will run on any computer that
supports the mode.
The computer’s display controller supports all VGA and Super VGA modes,
the most widely used industry standards.
Video modes
The computer supports video modes defined in the tables below. If your
application offers a selection of mode numbers that do not match the
numbers on the table, select a mode based on mode type, resolution,
character matrix, number of colors and refresh rates. Also, if your software
supports both graphics and text modes, the screen display may appear to
operate faster using a text mode.

AT Commands
In most cases, you will not need to type AT commands manually. However,
there might be some occasions when you will need to do so.
This chapter describes AT commands for data mode. Fax and voice
commands are taken care of by application software.
The format for entering AT commands is:
ATXn
where X is the AT command, and n is the specific value for that command.
After you type in the command press ENTER.
Any command issued is acknowledged with a response in either text or
numeric values known as result codes.
All commands and command-values accepted by the modem are
described in this section; any entry other than those listed results in an
error.
+++ Escape sequence
The escape sequence allows the modem to exit data mode and enter online command mode. While in on-line command mode, you can
communicate directly to your modem using AT commands. Once you
finish, you can return to data mode using the ATO command.
A pause, the length of which is set by Escape Guard Time (S12), must be
completed after an escape sequence is entered. This pause prevents the
modem from interpreting the escape sequence as data.
The value of the escape sequence character may be changed using
register S2.
A/
Repeat last command
This command repeats the last command string entered. Do not precede
this command with an AT prefix or conclude it by pressing Enter.
Answer command
This command instructs the modem to go off-hook and answer an incoming
call.

S-registers
S-registers contain the settings that determine how a number of functions
of the internal modem operate. For example, how many times to let the
telephone ring before the modem answers and how long to wait before it
hangs up if a connection fails. You can also customize certain AT
commands such as the escape sequence and command line termination.
The contents of the registers are changed automatically when you modify
corresponding settings in your communication software. If you choose,
however, you can display and edit the contents of the registers manually
when the modem is in command mode. If the value is out of the acceptable
range, then an error is generated.
This chapter describes the settings for each S-register.
S-register values
The format for displaying the value of an S-register is:
ATSn?
where n is the register number. After you type in the register press ENTER.
The format for modifying the value of an S-register is:
ATSn=r
where n is the register number, and r is the new register value. After you
type in the register and its new value press ENTER.
Some registers vary from one country/region to another.
S0
Auto answer ring number
This register determines the number of rings the modem will count
before automatically answering a call. Enter 0 (zero) if you do not
want the modem to automatically answer at all. When disabled,
the modem can only answer with an ATA command.

S5
Command line editing character (user defined)
This register sets the character recognized as a backspace and
pertains to asynchronous only. The modem will not recognize the
backspace character if it is set to a value that is greater than 32
ASCII. This character can be used to edit a command line. When
the echo command is enabled, the modem echoes back to the
local DTE the backspace character, an ASCII space character,
and a second backspace character. This means a total of three
characters are transmitted each time the modem processes the
backspace character.
Range: 0-127, ASCII decimal
Default: 8 (backspace)
Units:
ASCII
S6
Wait before dialing
This register sets the length of time, in seconds, that the modem
must wait (pause) after going off-hook before dialing the first digit
of the telephone number. The modem always pauses for a
minimum of two seconds, even if the value of S6 is less that two
seconds. The wait for dial tone call progress feature (W dial
modifier in the dial string) will override the value in register S6.
This operation, however, may be affected by some ATX options
according to country/region restrictions. In some countries/regions,
S6 will set dial tone detect time.
Range: 3-255
Default: 3
Units:
seconds
S7
Connection completion time-out
This register sets the time, in seconds, that the modem must wait
before hanging up because carrier is not detected. The timer is
started when the modem finishes dialing (originate), or goes offhook (answer). In originate mode, the timer is reset upon detection
of an answer tone if allowed by county restriction. The timer also
specifies the wait for silence time for the @ dial modifier in
seconds. S7 is not associated with the W dial modifier.

V.90
The TOSHIBA internal modem uses V.90 technology. The modem is
capable of downstream speeds of 56kbps (kilobits per second) when
connected to an Internet service provider that supports V.90. As with any
modem, the actual throughput (speed of data transfer) depends on analog
telephone line conditions, which can vary considerably. Therefore, many
users will experience throughput in the range of 28-50kbps under normal
telephone line conditions. Upstream data flows at the V.34 rate.
V.90 rates can be achieved only when one V.90-capable host modem is
connected to another. The TOSHIBA Internal modem will select
automatically V.34 if the remote modem lacks V.90 capability or if a
combination of network and/or phone line conditions prevent V.90
connection.

Radio Characteristics
Radio Characteristics of Wireless LAN Cards may vary according to:
■ Country/region where the product was purchased
■ Type of product
Wireless communication is often subject to local radio regulations.
Although Wireless LAN wireless networking products have been designed
for operation in the license-free 2.4GHz/5GHz band, local radio regulations may
impose a number of limitations to the use of wireless communication
equipment.
Refer to the sheet “Information to the User” for regulatory information that
may apply in your country/region.

■ DSSS-CCK, DSSS-DQPSK, DSSS-DBPSK
(Revision B)
■ OFDM-BPSK, OFDM-QPSK, OFDM-16QAM,
OFDM-64QAM (Revision A,G)
The range of the wireless signal is related to the transmit rate of the
wireless communication. Communications at lower transmit range may
travel larger distances.
■ The range of your wireless devices can be affected when the antennas
are placed near metal surfaces and solid high-density materials.
■ Range is also impacted due to "obstacles" in the signal path of the radio
that may either absorb or reflect the radio signal.
Supported Frequency Sub-bands
Subject to the radio regulations that apply in the countries/regions, your
Wireless LAN card may support a different set of 2.4 GHz/5GHz channels.
Consult your Authorized Wireless LAN or TOSHIBA Sales office for
information about the radio regulations that apply in the countries/regions.

■ For wireless clients that operate in a Wireless LAN Infrastructure, the
Wireless LAN card will automatically start operation at the channel
identified by the Wireless LAN Access Point. When roaming between
different access points the station can dynamically switch to another
channel if required.
■ For Wireless LAN cards installed in wireless clients that operating in a
peer-to-peer mode, the card will use the default channel 10.
■ In a Wireless LAN Access Point, the Wireless LAN card will use the
factory-set default channel (printed in bold), unless the LAN
Administrator selected a different channel when configuring the
Wireless LAN Access Point device.
