Quick Solutions Checklist
Is the Notebook Receiving Adequate Power?
If the power indicator light is off and the notebook cannot be
turned on, adequate power may not be available to the notebook.
On some models the power indicator light is the AC adapter light.
On other models the power indicator is the battery light. To
identify the power indicator light on your notebook, refer to your
model-specific documentation.
To make sure adequate power is available to the notebook:
■
If the notebook is running on battery power or is connected
to an external power source other than an electrical outlet,
connect the notebook to an electrical outlet using the
AC adapter. If the notebook turns on when connected to
external power but not when running on a battery pack,
recharge or replace the battery pack.
■
■
■
Make sure the power cord and AC adapter cable connections
are secure.
Verify that the electrical outlet is providing adequate power
by plugging another electrical device into the outlet.
Plug the notebook (through the AC adapter) into an outlet in a
different room and on a different circuit.
When the notebook is receiving adequate power, the power
indicator light (AC adapter light or battery light) turns on.
Is the Notebook Turned On?
The notebook may be in Standby or in Hibernation. To resume
the notebook from Standby or restore from Hibernation:
■
If your model has a power button, briefly press the power
button.
■
If your model has a power switch, briefly slide the power
switch as described in your model-specific documentation.

Is the Notebook Overheated?
It is normal for the notebook to feel warm to the touch while it is
in use. But if the notebook feels extremely warm, it may be
overheating because a vent is blocked. Overheating can cause the
notebook to become unresponsive.
If you suspect that overheating could be causing the problem,
allow the notebook to cool to room temperature. Then:
■
Use the notebook on a hard surface, not on a soft surface. A
rug, pillow, thick clothing, upholstery, or other fabric could
block an underside vent.
■
Position the notebook so that no side or rear vent is blocked
by a vertical surface such as a wall or optional equipment.
Is the System Unresponsive?
If the system has stopped responding, you may need to restart or
shut down and then start up the notebook. If you are unable to use
normal Windows restart or shutdown procedures:
1. Press ctrl+alt+delete. Then:
❏
In Windows 2000 Professional, select the Shut Down
button, press the down arrow beside the What Do You
Want The Computer To Do field until Restart or Shut
Down is displayed, then select the OK button.
❏
In Windows XP, select the Turn Off Computer button,
then select the Turn Off button.
2. If you are unable to shut down the notebook with
ctrl+alt+delete:
❏
On a model with a power button, press and hold the
power button for 5 seconds.
❏
On a model with a power switch, slide and hold the
power switch for 5 seconds.

3. If your model has a reset button, insert the end of a small
object like a straightened paper clip into the reset button, then
press the power button. (This restarts the notebook.) For
information about a reset button on your model, refer to the
Startup Guide, Hardware Guide, or Reference Guide
included with your notebook.
4. If you are unable to turn off the notebook with the power
button or power switch, or to restart the notebook with the
reset button, disconnect the notebook from external power,
then remove the battery pack.
Is an External Device Not Working?
If an external device does not function as expected:
■
Turn on the device exactly as instructed in the device
documentation. (Some optional devices, such as external
monitors, printers, and devices connected to a parallel
connector, must be turned on before the notebook is
turned on.)
■
Verify that:
❏
The device is connected to the correct jack, port, or
connector.
❏
❏
❏
All device connections are secure.
The device is receiving adequate electrical power.

Problems and Solutions
Before You Begin
This chapter contains general solutions to problems that you may
encounter with your notebook. Try the solutions one at a time. If
a single problem has multiple solutions, try the solutions in the
order in which they are presented.
Because the listed problems and solutions are general:
■
■
■
The problems and solutions apply to most, but not all,
notebooks. Some problems and solutions may not apply to
your model.
For example, some models may not have volume control
buttons; others may not have drive bays. If a solution involves
hardware or software that is not available on your model, try
the other solutions.
The solutions do not include detailed procedures which vary
by model. For detailed model-specific procedures, refer to the
model-specific documentation included with your notebook.
For example, if a solution suggests that you update system
ROM, you might need to refer to a guide entitled Software
Guide or Reference Guide to obtain ROM update instructions
for your model.
The problems and solutions include alternate terms for
similar features.
For example, some models have a power button and others
have a power switch. Since power buttons and power
switches have similar functions, a solution may suggest that
you “press the power button (or slide the power switch).”

card and will increase if you stop playing the DVD or when the
backup is complete.
If the time remaining display seems inaccurate even when the level of
power use remains constant, refer to “To increase the accuracy of all
battery pack charge displays,” next in this section.
■
To increase the accuracy of all battery pack charge displays:
❏
Fully charge a new battery pack before using it to run the
notebook.
❏
Allow an in-use battery pack to discharge to less than 10 percent
of a full charge through normal use before charging it.
❏
❏
When you charge any battery pack, charge it fully.
Calibrate the battery pack, especially if it has not been used for
1 month or more. For instructions, refer to your model-specific
documentation.
■
Replace the battery pack. It may be defective or have reached the end
of its useful life. Battery life varies with battery pack power usage and
maintenance procedures.

If the device requires external power, be sure that it is plugged
securely into an electrical outlet as well as into a USB connector on
the notebook.
■
■
■
Verify that the device is functioning properly by connecting it to a
USB connector on another system.
Verify with the device manufacturer that you are using the correct
driver(s).
Use the Device Manager utility in your operating system to check for
and resolve any resource conflicts.
USB device does not work during startup
Refer to your model-specific documentation for information about USB
legacy support. (USB legacy support enables a USB device, such as an
optional external keyboard or mouse, to function during startup, before
Windows loads.)

Problems and Solutions
Wireless LAN (WLAN) Device Problems
See also the “Internet Problems” section.
✎
Notebook cannot connect to wireless network
■
Verify that the wireless device is turned on. On most models, a light
turns on or changes color when the device is turned on. For more
information about turning a wireless LAN device on and off and
about using the wireless LAN device indicator on your notebook,
refer to your model-specific documentation.
■
■
■
Verify that the antenna(s) are free from obstructions. For information
about the number and location of antennas on your notebook refer to
your model-specific documentation.
Verify that you are within optimal range of an access point (for an
infrastructure connection) or another wireless-equipped computer
(for an ad hoc connection).
Use the Device Manager utility in your operating system to verify that
the correct wireless LAN device driver is loaded and functioning
properly.
■
■
■
Verify that you are using the correct SSID.
Verify that the wireless encryption settings are correct.
If you are trying to connect to an ad hoc network, ensure that the
channel settings are correct.
■
Consider that wireless LAN performance may be affected by the
following factors:
❏
Type and thickness of building construction materials (brick,
steel, concrete, glass, etc.)
❏
Nearby electronic and communications equipment and HVAC
system.

Problems and Solutions
❏
❏
People or objects moving into the range of the antenna and
access point.
The number of users connecting at one time in a single area to a
single access point.
❏
❏
The concentration of access points within an area.
Channel utilization.
Notebook cannot access network resources
■
If you are logging on to a wireless network via an access point but
your notebook cannot connect to network resources, your notebook
may not have been assigned an IP address. You may have to release
and renew your network IP address at the command prompt using the
ipconfig commands release and renew.
■
Verify that the wireless encryption settings are correct.
Connection breaks after 3 minutes
If Windows XP Service Pack 1 is installed on your notebook, your
wireless LAN device authentication is enabled by default. Enabled
wireless LAN device authentication requires that an authentication
server exist on the network in order for a wireless LAN device to gain
access to the network. If the wireless LAN device on your notebook has
wireless LAN device authentication enabled and an authentication server
does not exist on the network, then the wireless connection will be lost
every 3 minutes.
If your network does not require wireless LAN device authentication, you
can avoid network disconnections by disabling the wireless LAN device
authentication on your notebook. To disable wireless LAN device
authentication:
1. Select Start > Control Panel > Network Connections.
2. Right-click the wireless connection, then select Properties.
3. Select the Wireless Networks tab.

Problems and Solutions
4. Select the network name in the Preferred Networks window, then
select Properties.
5. Select the Authentication tab.
6. Make sure the check box for authentication is cleared.
7. Select Apply, then select OK.
Notebook cannot connect to Internet when
WEP is enabled on the access point
The Windows XP Service Pack 1 changes the numbering of the WEP
(Wireless Encryption Protocol) key index from the numbering assigned to
the key in the original release of Windows XP. In the original (XP Gold)
release, the index keys are numbered 0 through 3. Windows XP Service
Pack 1 (SP1) changes the numbering of the index keys to 1 through 4.
As a result, if you were using WEP key 1 on a client with Windows
XP Gold, you would need to use WEP key 2 with the same client under
Windows XP SP1.
Rate indication in the Connection Status
fluctuates
If the rate indication in the Connection Status fluctuates even though the
unit is stationary, no action may be necessary.
The algorithm for data rate determination checks the data packet by
packet and adjusts the data rate for current conditions. Lost or corrupted
packets will cause the data rate to fall back, and subsequent good packets
will cause the rate to increase.
Packets can be lost or corrupted by over-the-air disturbances. For
example, in an office environment, other transmissions from other
WLANs may cause disturbances. In a home environment, disturbances
may be caused by microwave ovens or cordless telephones.
Some WLAN cards do not update their rate indications and may not
display the actual connection rate.

Problems and Solutions
Throughput and connection range vary
If there are large variations in throughput and range even when equipment
is stationary, the cause may be nearby sources of radio frequency
interference. WLAN radios operate in unlicensed frequency bands where
many other sorts of radio devices may also operate. Such radio devices
may severely impact performance of the WLAN. Devices which may
cause interference include cordless telephones, microwave ovens, and
Bluetooth radio devices.
If the problem is due to a cordless telephone, either the telephone or the
WLAN device can be moved to another frequency in the band for
improved performance. For channel changing instructions, refer to your
telephone or WLAN device documentation.
Notebook cannot detect a Bluetooth device
■
Verify that the Bluetooth device is turned on.
❏
❏
Some Bluetooth phones must be set for detection and may be
detectable by other devices for only a short time.
On most notebooks, the device configuration is available in the
Entire Bluetooth Neighborhood. For more information, refer to
the documentation included with the Bluetooth device.
■
■
Refresh the list of Bluetooth devices as instructed in your Bluetooth
documentation.
Verify that:
❏
❏
The Bluetooth search for devices is active.
Device responses to the Bluetooth search are not filtered.
