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 Stand by 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 
Ctrl, Alt, and Del simultaneously.
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 225.
The computer is not accessing the hard disk or the 
diskette drive. 
Your computer normally loads the operating system from the 
hard disk. If you have a hard disk problem, you will not be 
able to start the computer. Insert a system diskette into the 
diskette drive, press the left or right arrow key and choose 
your boot-up device.
HINT: Press F12 as you power on the computer to access the
menu.

The computer displays the WARNING RESUME FAILURE 
message.
The computer was placed in Stand by mode and the battery 
has discharged. Data stored in the computer’s memory has 
been lost. 
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 229. 
The computer displays the Non-System disk or disk error 
message. 
Make sure there is no diskette in the diskette drive. If there is 
one, remove it and press any key to continue. If pressing any 
key does not work, 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.

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.
My browser can’t find a site I bookmarked.
The World Wide Web is constantly changing. A site you 
bookmarked yesterday may not be available today or its 
server may be down for temporary repair. Try again later.
The Windows® XP operating system can help you

Resolving a hardware conflict
If you receive an error message telling you there is a device 
driver conflict or a general hardware problem, try using 
Windows
® Help and Support to troubleshoot the problem 
first.
For help on hardware conflicts:
1Click Start, then click Help and Support.
2Click the Hardware link in the window’s left pane.
A list of category links appear.
3Click the Fixing a hardware problem.
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 
successful 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  
						

							226
If Something Goes Wrong
Resolving a hardware conflict
5.375 x 8.375 ver 2.4.0
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.
Interrupt Request Channel 
The channel to the CPU is called an Interrupt Request (IRQ) 
because it interrupts what the processor is doing and requests 
some of the processor’s time. If two or more devices use the 
same IRQ, the processor does not know which device is 
asking for attention. This may cause a hardware conflict.
NOTE: One of the IRQs may be shared by multiple devices. This is 
called IRQ sharing and is normal.
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, causing a hardware conflict.
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.
❖Disable another system component and use its resources 
for the new device, see “Fixing a problem with Device 
Manager” on page 227.

❖Reconfigure the device so that its requirements do not 
conflict. Refer to the device’s documentation for 
instructions about changing settings on the device.
Fixing a problem with Device Manager 
Device Manager provides a way to check and change the 
configuration of a device.
CAUTION: Changing the default settings using Device Manager 
can cause other conflicts that make one or more devices unusable. 
Device Manager is a configuration tool for advanced users who 
understand configuration parameters and the ramifications of 
changing them.

Memory module 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 your computer according to the instructions in 
“Turn Off or Shut down command” on page 98. 
						

							229
If Something Goes Wrong
Resolving a hardware conflict
5.375 x 8.375 ver 2.4.0
2Remove the memory module, following the instructions 
in “Removing a memory module” on page 52.
3Reinstall the memory module, following the instructions 
in “Installing additional memory (optional)” on page 47, 
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.
Power and the batteries 
Your computer receives its power through the AC adapter 
and power cable or from the system batteries (main battery 
and real-time clock (RTC) 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.
If the AC power light still does not come on, check that the 
wall outlet is working properly by plugging in a lamp or other 
appliance.
The AC adapter and power cable work correctly, but the 
battery will not charge.
The main battery may not be inserted correctly in the 
computer. Turn off the computer, remove the battery, clean 
the contacts with a soft dry cloth (if necessary) and replace 
the battery. 
						

							230
If Something Goes Wrong
Resolving a hardware conflict

The battery may be too hot or too cold to charge properly. If 
you think this is the probable cause, let the battery reach 
room temperature and try again.
If the battery has completely discharged, it will not begin 
charging immediately. Leave the AC adapter and power cable 
connected, wait 20 minutes and see if the battery is charging.
If the battery light is glowing after 20 minutes, let the 
computer continue charging the battery for at least another 20 
minutes before you turn on the computer.
If the battery light does not glow after 20 minutes, the battery 
may have reached the end of its useful life. Try replacing it.
The battery appears not to power the computer for as 
long as it usually does.
If you frequently recharge a partially charged battery, it may 
not charge fully. Let the battery discharge completely, then 
try charging it again.
Check the power options using the Power Management 
utility. Have you added a device, such as a PC Card or 
memory module, that takes its power from the battery? Is 
your software using the hard disk more? Is the display set to 
turn off automatically? Was the battery fully charged to begin 
with? All these conditions affect how long the charge lasts.
For more information on maximizing battery power, see 
“Charging batteries” on page 118.
Keyboard problems
If, when you type, strange things happen or nothing happens, 
the problem may be related to the keyboard itself.
The keyboard produces unexpected characters.
A keypad overlay may be on. If the numeric keypad or cursor 
control light is on, press 
Fn and F10 simultaneously to turn off 
the cursor control light or press 
Fn and F11 simultaneously to 
turn off the numeric keypad light.
