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 problem-

related 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.

9-2 User’s Manual

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.

Hardware and system checklist

This section discusses problems caused by your computer’s hardware or

attached peripherals. Basic problems may occur in the following areas:

System start-up

When the computer does not start properly, check the following items:

■Self Test

■Power Sources

■Power-on Password

Software 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.

Hardware 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.

HDD Drive Capacity

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.

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.

Appendix C

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 on-

line 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

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.

A 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.

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.

Range: 0-255

Default: 0

Units: rings

Some registers vary from one country/region to another.

D-2 User’s Manual

S-registers

S1 Ring counter

This register is read only. The value of S1 is incremented with

each ring. If no ring occurs over a six-second interval, this register

is cleared.

Range: 0-225

Default: 0

Units: rings

S2 AT escape character (user defined)

This register determines the ASCII values used for an escape

sequence. The default is the + character. The escape sequence

allows the modem to exit data mode and enter command mode

when on-line. Values greater than 127 disable the escape

sequence.

Range: 0-255, ASCII decimal

Default: 43

Units: ASCII

S3 Command line termination character (user defined)

This register determines the ASCII values as the carriage return

character. This character is used to end command lines and result

codes.

Range: 0-127, ASCII decimal

Default: 13 (carriage return)

Units: ASCII

S4 Response formatting character (user defined)

This register determines the ASCII value used as the line feed

character. The modem uses a line feed character in command

mode when it responds to the computer.

Range: 0-127, ASCII decimal

Default: 10 (line feed)

Units: ASCII

User’s Manual D-3

S-registers

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 off-

hook (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.

Range: 1-255

Default: 50

Units: seconds

D-4 User’s Manual

S11 DTMF dialing speed

This register determines the dialing speed which is prefixed for

each country/region.

Range: 50-255

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 mode

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.

Wireless LAN

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.

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.

Refer to the sheet “Information to the User” for regulatory information that

may apply in your country/region.

Wireless IEEE 802.11 Channels Sets (Revision B and G)

*1 Factory-set default channels

*2 Refer to the sheet Approved Countries/Regions for use for the countries/

regions that in which these channels can be used.

When installing Wireless LAN cards, the channel configuration is managed

as follows:

■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.

bus: An interface for transmission of signals, data or electric power.

byte: The representation of a single character. A sequence of eight bits

treated as a single unit; also the smallest addressable unit within the

system.

cache memory: High speed memory which stores data that increases

processor speed and data transfer rate. When the CPU reads data

from main memory, it stores a copy of this data in cache memory.

The next time the CPU needs that same data, it looks for it in the

cache memory rather than the main memory, which saves time. The

computer has two cache levels. Level one is incorporated into the

processor and level two resides in external memory.

capacity: The amount of data that can be stored on a magnetic storage

device such as a floppy disk or hard disk. It is usually described in

terms of kilobytes (KB), where one KB = 1024 bytes and megabytes

(MB), where one MB = 1024 KB.

card: Synonym for board. See board.

CardBus: An industry standard bus for 32-bit PC cards.

CD-ROM: A Compact Disc-Read Only Memory is a high capacity disc that

can be read from but not written to. The CD-ROM drive uses a laser,

rather than magnetic heads, to read data from the disc.

CD-R: A Compact Disc-Recordable disc can be written once and read

many times. See also CD-ROM.

CD-RW: A Compact Disc-ReWritable disc can be rewritten many times.
