Help" for more information about how to get help.
Safety
guidelines
While
troubleshooting your computer, follow these safety guidelines:
|
Never
remove the memory bay cover or Mini PCI cover (Mini PCI
cover not available on all models) while your computer is turned on.
|
|
Make
sure you are properly grounded before accessing internal components.
For more information about preventing damage from static electricity,
see "Preventing static electricity" below. |
Preventing
static electricity
The
components inside your computer are extremely sensitive to static electricity,
also known as
electrostatic discharge
(ESD).
|
|
ESD
can permanently damage electrostatic discharge sensitive components
in the computer. Prevent ESD damage by following ESD guidelines
every time you open the computer case.
|
Before
opening the computer case, follow these guidelines:
|
Turn
off the computer power. |
|
Wear
a grounding wrist strap (available at most electronics stores) and
attach it to a bare metal part of the computer. |
|
|
To
prevent risk of electric shock, do not insert any object into
the vent holes.
|
|
Touch
a bare metal surface on the back of the computer. |
|
Unplug
the power and modem cables. |
|
Remove
the battery pack. |
Before
working with computer components, follow these guidelines:
|
Avoid
static-causing surfaces such as carpeted floors, plastic, and packing
foam. |
|
Remove
components from their antistatic bags only when you are ready to use
them. Do not lay components on the outside of antistatic bags because
only the inside of the bags provide electrostatic protection.
|
|
Always
hold memory modules and expansion cards by their edges. Avoid touching
the edge connectors and components on the cards. Never slide expansion
cards or memory modules over any surface. |
|
|
To
avoid exposure to dangerous electrical voltages and moving parts,
turn off your computer and unplug the power cord before opening
the case.
|
First
steps
If
you have problems with your computer, try these things first:
|
Make
sure the power adapter is connected to your computer and an AC outlet
and that the AC outlet is supplying power. |
|
If you
use a power strip or surge protector, make sure it is turned on.
|
|
If a
peripheral device does not work, make sure that all connections are
secure. |
|
Make
sure that your hard drive is not too full. |
|
If an
error message appears on the screen, write down the exact message.
The message may help technical support in diagnosing and fixing the
problem. |
|
If you
added or removed modules or peripheral devices, review the installation
procedures you performed and make sure you followed each instruction.
|
|
If an
error occurs in a program, consult the printed documentation or the
online Help for the program. |
|
On the
Windows desktop, double-click the
QuickAnswers
or
HelpSpot
icon for additional troubleshooting information. |
|
|
Do
not try to troubleshoot your problem if power cords or plugs
are damaged, if your computer was dropped, or if the cabinet
was damaged. Instead, unplug your computer and contact a qualified
computer technician.

A
DVD movie will not play
|
Make
sure the label is facing up. |
|
Shut
down and restart your computer. |
|
The DVD's
regional code and your computer's regional code may not match.
Regional codes
help control DVD title exports and help reduce illegal disc distribution.
To be able to play a DVD, the regional code on the disc and the regional
code for the DVD drive must match. |
The regional
code on your DVD drive is determined by delivery address for your computer.
The regional code for the disc is on the disc, disc documentation, or
packaging.
To
clean a CD or DVD:
|
Wipe
from the center to the edge, not around in a circle, using a product
made especially for the purpose. |

the same telephone line as the modem. |
|
Make
sure that you are not using a digital, rollover, or PBX line. These
lines do not work with your modem. |
|
Check
for line noise (scratchy, crackling, or popping sounds). Line noise
is a common problem that can cause the modem to connect at a slower
rate, abort downloads, or even disconnect. The faster the modem, the
less line noise it can tolerate and still work properly. |
Listen to
the line using your telephone. Dial a single number (such as 1).
When the dial tone stops, listen for line noise. Wiggle the modem cable
to see if that makes a difference. Make sure the connectors are free
from corrosion and all screws in the wall or telephone wall jack are
secure.
You can
also call your telephone service and have them check the telephone line
for noise or low line levels.
|
Try another
telephone line (either a different telephone number in your house
or a telephone line at a different location). If you can connect on
this line, call your telephone company. |
|
Try connecting
with the modem at a lower connection speed. If reducing the connect
speed lets you connect, contact your telephone company. The telephone
line may be too noisy. |
You
cannot connect to the Internet
|
The ISP
may be having technical difficulties. Contact your ISP technical support
for help. |
|
See if
the modem works with a different communications program. The problem
may be with just one program. |
Your
56K modem does not connect at 56K
Current
FCC regulations restrict actual data transfer rates over public telephone
lines to 53K. Other factors, such as line noise, telephone service provider
equipment, or ISP limitations, may lower the speed even further.
