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. 
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.

Troubleshooting
9-2TOSHIBA TE2300 ■ 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 diskette is correctly inserted and that the diskette’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, diskette 
drives, hard disk drive, printer, 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? Print a copy of the screen if you have a printer 
attached. 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 icons 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. 
Software The problems may be caused by your software 
or diskette. If you cannot load a software 
package, the media (usually a diskette) 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.

9-3TOSHIBA TE2300 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. 
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 
■ Self test   
■ Power   
■ Password  
■ Keyboard  
■ LCD panel   
■ Hard disk drive 
■ DVD-ROM drive 
■ CD-RW/DVD-ROM drive 
■ Diskette drive  
■ Infrared port   ■ Printer 
■ Pointing device 
■ PC card   
■ Monitor 
■ Sound system  
■ TV output signal 
■ USB 
■ Modem

System start-up  
When the computer does not start properly, check the following items: 
■ Self Test 
■ Power Sources 
■ Power-on Password  
Self test  
When the computer starts up, the self-test will be run automatically, and 
the following will be displayed: 
In Touch with Tomorrow 
TOSHIBA
 
This message remains on the screen for a few seconds. 
If the self test is successful, the computer tries to load the operating 
system. Depending on how the Boot Priority is set in the Hardware Setup, 
the computer tries to load first from drive A then from drive C, or first from 
drive C then from drive A.

9-4TOSHIBA TE2300 If any of the following conditions are present, the self test failed: 
■ The computer stops and does not proceed to display information or 
messages. 
■ A beep sounds, and after a few seconds no new messages appear. 
■ Random characters appear on the screen, and the system does not 
function normally. 
■ The screen displays an error message. 
Turn off the computer and check all cable connections. If the test fails 
again, contact your dealer. 
Power 
When the computer is not plugged into an AC adaptor, the battery pack is 
the primary power source. However, your computer has a number of 
other power resources, including intelligent power supply and Real Time 
Clock battery. These resources are interrelated and any one could affect 
apparent power problems. This section provides check lists for AC 
adaptor and the main battery. If you cannot resolve a problem after 
following them, the cause could lie with another power resource. In such 
case, contact your dealer. 
Overheating power down 
If the computer’s internal temperature becomes too high, the computer 
will automatically enter Hibernation or Resume mode and shut down. 
Problem Procedure 
Computer shuts down 
and DC IN indicator 
blinks orange Leave the computer off until the DC IN indicator 
stops blinking. 
It is recommended to leave the computer off until 
the its interior reaches room temperature even 
though the DC IN indicator stops blinking. 
If the computer has reached room temperature 
and still does not start, or if it starts but shuts 
down quickly contact your dealer. 
Computer shuts down 
and its DC IN indicator 
is flashing green   Indicates a problem with the heat dispersal 
system. Please contact your dealer.
