Some problems you may encounter when using your notebook
computer are relatively easy to identify and solve. Others may require help
from your dealer, your network administrator or the manufacturer of a software
program.

Problems to 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 press a key, nothing happens.
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 Ctrl, Alt, and Del
simultaneously.
Clearing the condition may get the computer running, but it
won’t solve a resource conflict.
The computer is not accessing the hard disk or the diskette
drive.

To charge the battery, leave the computer plugged into a
live wall outlet for several hours.
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 Start-up menu to fix the problem.
Using Start-up options to fix problems
If the operating system fails to start properly, you may
have to change your system’s configuration or verify the start-up procedure to
fix the problem. To do this, use the options in the Startup menu. This section
describes each option and when to use the procedure.
To open the Start-up menu:
1 Restart your computer.
2 Press F8 When your computer starts. The Windows Advanced Options menu displays
these options:
Safe Mode
Safe Mode (with
Networking)
Safe Mode (with
Command Prompt)
Enable Boot Logging
Enable VGA Mode
Last known good
configuration (your most recent settings that worked)
Directory Services
Restore Mode (Windows domain controllers only)
Debugging Mode
Start Windows
normally
Reboot
Return to OS Choices
(menu)
TECHNICAL NOTE: If your computer is connected to a network,
the Start-up menu may display different versions of Safe mode.
Internet problems
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.
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.
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.
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:
1 Click Start, then click Help and Support.
2 Click the Hardware link in the window’s left pane. A list of category links appears.
3 Click the Fixing a hardware problem.
4 Choose 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.
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.
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.
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.
Disabling a device
1 Click Start, Control Panel, Performance and Maintenance,
Administrative Tools.
2 Double-click the Computer Management icon.
3 In the left pane, click Device Manager.
4 Select the specific device from the device category.
5 In the toolbar, look to the far right for an icon of a
monitor with a strike mark through a circle on the front. This is the disable
feature.
6 Click the icon. You
are given the option of disabling the device.
7 Click yes or no, whichever is appropriate.
Checking device properties
Device Manager provides a way to view the properties of a
device. Properties include the name of the manufacturer, the type of device,
the drivers installed, and the system resources assigned to the device.
To check a device’s properties:
1 Click Start, Control Panel, Performance and Maintenance,
Administrative Tools.
2 Double-click the Computer Management icon.
3 In the left pane, click Device Manager.
4 To view the device(s) installed, double-click the device
type.
5 To view the properties, double-click the device. The operating system displays the Device
Properties window, which provides an array of tabs. They include:
The General tab, which provides basic information about the
device.
The Resource tab, which lists resources assigned to the
monitor, DVD-ROM, DVD-ROM/CD-RW, diskette drive, and other power-using
functions.
The Drivers tab, which displays the drivers being used by
the device.
A Troubleshooting button is also present.
Click troubleshooting.
A Help and Support window for that device appears.
