6Save the file and refer to it when you contact the software 
manufacturer.
Problems when you turn on the computer 
These problems may occur when you turn on the power.
The computer will not start.
Make sure you attached the AC adapter and power cable 
properly or installed a charged battery.
Press and hold down the power button for a few seconds.
If you are using the AC adapter, check that the wall outlet is 
working by plugging in another device, such as a lamp.
The computer starts but, when you press a key, nothing 
happens. 
You are probably in Standby mode and have a software or 
resource conflict. When this happens, turning the power on 
returns you to the problem instead of restarting the system. 
To clear the condition, press the power button until it turns off 
the computer.
Clearing the condition may get the computer running, but it 
won’t solve a resource conflict. Read the documentation that 
came with the conflicting device and “Resolving a hardware 
conflict” on page 185.
The computer displays the WARNING RESUME FAILURE 
message.
The computer was placed in Standby mode and the battery 
has discharged. Data stored in the computer’s memory has 
been lost. Press Enter to continue booting. 
To charge the battery, leave the computer plugged into a live 
wall outlet for several hours. For more information, see 
“Power and the batteries” on page 190.

The Windows
® operating system is not working
5.375 x 8.375 ver 2.3
The computer displays the Non-System disk or disk error 
message. 
Press any key. If this does not resolve then problem, press 
Ctrl, Alt, and Del to restart the computer. 
The Windows® operating system is not 
working
Once you are familiar with the desktop and used to the way 
the operating system responds to your work routine, you can 
easily detect if the operating system is not working correctly. 
For example:
❖The operating system fails to start after the Starting 
Windows XP message appears.
❖The operating system takes a long time to start.
❖The operating system responds differently from the 
normal routine.
❖The screen does not look right.
Unless a hardware device has failed, problems usually occur 
when you change the system in some way such as installing a 
new program or adding a device.
If you experience any of these problems, use the options in 
the Startup menu to fix the problem.
Using Startup options to fix problems
If the operating system fails to start properly, you may have to 
change your system’s configuration or verify the startup 
procedure to fix the problem. To do this, use the options in 
the Startup menu.
To open the Startup menu:
1Restart your computer.
2Press F8 when your computer starts.

Internet problems
My Internet connection is very slow.
Many factors contribute to the speed with which you can surf 
the Internet. They include: modem speed, time of day (when 
everyone else is surfing, your access can be slow) and 
popularity of the site. If accessing a particular site is very 
slow, try later.
My browser can’t find the URL address I typed in.
Make sure you separated the domain names of the address 
with the forward slash (/). Check the spelling of each name 
and the syntax of the address carefully. A single incorrect 
letter or missed character, comma instead of period (“dot”) or 
other mistake makes it impossible for your browser to locate 
the site.

4Choose from specific topics and follow the steps.
If there is still a problem, the operating system should display 
a message that explains what the conflict is.
A plan of action
The smooth operation of the system depends on the 
interaction of all devices, programs, and features. If the 
system or one of its attached devices isn’t working, resolving 
the problem can be time-consuming and frustrating.
The recommended procedure for getting multiple devices to 
work together is to add and set up one device at a time. After 
you add each device, test it to make sure it and all previously 
connected devices work.
The device most recently connected to the system is the one 
most likely to be causing a hardware conflict.
Resolving hardware conflicts on your own 
Computer components need resources to accomplish a task. 
A device, such as a disk drive or a modem, needs a channel to 
the computer’s Central Processing Unit (CPU). It also needs a 
direct channel to the computer’s memory to store information 
as it works. These channels of communication are commonly 
referred to as system resources.
Direct Memory Access 
Similarly, the data required by the device is stored in a 
specific place or address in memory called the Direct 
Memory Access (DMA). The DMA provides a dedicated 
channel for adapter cards to bypass the microprocessor and 
access memory directly. If two or more devices use the same 
DMA, the data required by one device overwrites the data 
required by the other. That may cause a hardware conflict.

Plug and Play 
With Plug and Play and the Windows® XP operating system, 
avoiding hardware conflicts is easy. Plug and Play is a 
computer standard that helps the system BIOS (basic input/
output system) and the operating system to automatically 
assign resources to Plug and Play-compliant devices. In 
theory, if every device connected to the computer is Plug and 
Play-compliant, no two devices will compete for the same 
system resources. Simply plug in the device and turn on your 
computer. The operating system automatically sets up your 
system to accommodate the new device.
If you install an older (legacy) device that the operating 
system cannot recognize, the operating system may have 
difficulty assigning resources to it. As a result, a hardware 
conflict can occur. To see what resources the operating 
system has assigned to the device, see “Checking device 
properties” on page 189.
Resolving conflicts
There are three things you can do to resolve hardware 
conflicts:
❖Disable the device.
For an older device, remove it from the computer. For a 
Plug and Play device.
❖Disable another system component and use its resources 
for the new device.
❖Reconfigure the device so that its requirements do not 
conflict. Refer to the device’s documentation for 
instructions about changing settings on the device.

Memory card problems 
Incorrectly connected or faulty memory modules may cause 
errors that seem to be device-related. It is worthwhile 
checking for these first:
1Turn off the computer via the Start menu.
2Remove the memory module.
3Reinstall the memory module, following the instructions 
in “Using the computer for the first time” on page 51, and 
making sure it is seated properly.
4Check for the error again.
5If the error recurs, remove the memory module entirely 
and check for the error again.
If removing the memory module eliminates the error, the 
memory module may be faulty. If the error recurs without 
the memory module installed, the error is not caused by 
the memory module.
NOTE: Toshiba recommends using only memory approved by 
To s h i b a .
Power and the batteries 
Your computer receives its power through the AC adapter and 
power cable or from the system batteries (main battery and 
optional secondary battery). Power problems are interrelated. 
For example, a faulty AC adapter or power cable will neither 
power the computer nor recharge the batteries.
Here are some typical problems and how to solve them:
The AC power light does not come on when you plug in 
the AC adapter and power cable.
Make sure the AC adapter and power cable are firmly 
plugged into both the wall outlet and the computer.
