Troubleshooting
|
This chapter provides possible solutions to common computer problems. Use the information to troubleshoot and correct typical hardware and software issues.
If the suggestions in this chapter do not correct the problem, see "Getting Help" for more information about how to get help.
First steps
|
Make sure that the power cable is connected to your computer and an AC outlet and that the AC outlet is supplying power.
|
|
If you use a power strip, make sure it is turned on.
|
|
If a peripheral such as the keyboard or mouse does not work, make sure that all connections are secure.
|
|
If you added or removed computer peripherals before the problem started, review the installation procedures to make sure everything was installed correctly.
|
CD drive
The computer does not recognize the CD drive
|
Make sure the CD label is facing up, then try again.
|
|
Try a different CD. Occasionally CDs are flawed and cannot be read by the CD drive.
|
|
Shut down and restart your computer.
|
|
Restart your computer, then enter the BIOS Setup utility by pressing F1. Make sure that the IDE controllers are enabled.
|
Audio CD does not produce sound
|
Make sure the CD label is facing up, then try again.
|
|
Make sure the volume controls are not muted and are turned up.
|
|
Shut down and restart your computer.
|
Handling and cleaning CDs
|
Do not expose CDs to sun or other strong light for long periods. Also, avoid high heat or humidity.
|
|
Handle CDs carefully to avoid scratching them, especially on the label side, which only has a thin layer of lacquer protecting the surface.
|
|
Do not use alcohol-based pens, ballpoint pens, or pencils to write on CDs. The ink may eventually eat through the lacquer surface and damage the data. Instead use felt tip pens.
|
|
When using recordable CDs, only use labels designed expressly for that purpose.
|
|
Store and ship CDs in their jewel cases or other protective containers.
|
|
Do not stack CDs together. They may stick to each other, causing the lacquer surface to peel off.
|
|
Avoid putting fingerprints on the bottom (recorded side) of the CD.
|
|
Clean CDs by wiping from the center to the edge, not around in a circle, using a product made especially for the purpose.
|
Diskette drive
Your computer does not recognize the diskette drive
|
Shut down and restart your computer.
|
You cannot save file to diskette or you get the message "disk is full or write-protected"
|
Delete unnecessary files on the diskette and try again.
|
|
Try a different diskette. Occasionally diskettes are flawed and cannot be read by the diskette drive.
|
|
Make sure the write-protection tab on the upper-right corner of the diskette is down (unprotected).
|
|
Make sure the diskette you are using is IBM-compatible.
|
The diskette drive LED is lit continuously
|
Remove the diskette from the drive. If the light stays on, try restarting your computer.
|
File management
You accidentally deleted a file
|
Restore the file in the Recycle Bin.
|
To restore files that were deleted in Windows:
|
-
Double-click
the Recycle
Bin icon.
- Right-click the file you want to restore, then select Restore.
|
|
Hard drive
You receive an "Insufficient disk space" error message
|
Empty the Recycle Bin by right-clicking the Recycle Bin icon and selecting Empty Recycle Bin from the menu.
|
|
Save your files to another disk or drive. If the hard drive is full, copy any files not regularly used to diskettes or other backup media, then delete them from the hard drive.
|
You cannot access the hard drive or you receive a "General failure reading drive C" error message
|
If a diskette is in the diskette drive, eject it and restart the computer.
|
|
Try restarting your computer by pressing Ctrl+Alt+Del.
|
|
If your computer has been subjected to static electricity or physical shock, you may need to reinstall the operating system.
|
Internet
You cannot connect to the Internet
|
Make sure your computer is connected to a phone line and the phone line has a dial tone. Use the Setup poster to make sure that the connections have been made correctly.
|
|
If you have the call waiting feature on your telephone line, make sure it is disabled.
|
|
Make sure your account with your Internet service provider (ISP) is set up properly. Contact your ISP technical support for help.
|
|
Make sure you do not have a problem with your modem. For information about solving modem problems, see "Modem."
|
You receive an "Unable to locate host" message and are unable to browse the Internet
This problem can occur when you have typed a URL (Web address) incorrectly, lost your Internet connection, or your ISP is having technical difficulties.
Double-check the URL or try a different URL. If the error message still appears, disconnect the ISP connection and close your browser. Then reconnect and open the browser. If you still get the error, you may have a problem with your Internet connection or ISP.
Connecting to a Web site takes too long
|
Condition of the phone lines in your residence
|
|
Condition of the phone lines and switches at your local telephone company
|
|
Condition of the Internet computers to which you connect and the number of users accessing those computers
|
|
Complexity of graphics and multimedia on Web pages
|
|
Having multiple Web browsers open, performing multiple downloads, and having multiple programs open on your computer
|
Keyboard
The keyboard does not work
|
Make sure the keyboard cable is plugged in correctly.
|
|
Try a keyboard that you know works to make sure the keyboard port works.
|
|
If you spilled liquid in the keyboard, turn off the computer and unplug the keyboard. Clean the keyboard and turn it upside down to drain it. Let the keyboard dry before using it again.
|
A key on the keyboard keeps repeating
|
Make sure nothing is resting on the keyboard.
|
|
Make sure a key is not stuck. Press each key to loosen a key that might be stuck, then restart the computer.
|
Modem
Your modem does not dial or does not connect
|
Make sure your computer is connected to the phone line and the phone line has a dial tone. Use the Setup poster to make sure that you connected the phone line to computer correctly.
|
|
Make sure that the modem cable is less than six feet (1.8 meters) long.
|
|
Check for a dial tone by plugging a working phone into the phone jack. Remove any line splitters or surge protectors from the phone line during testing.
|
|
If you have additional phone services, such as call waiting, call messaging, or voice mail, make sure that all messages are cleared and call waiting is disabled before using the modem. Contact your phone service to get the correct code to temporarily disable the service. Also make sure the modem dialing properties are set appropriately.
|
To check the dialing properties:
|
-
Click
Start,
then select Settings,
then Control
Panel. The Control
Panel opens.
-
Double-click
the Modems
icon, then click Dialing
Properties. The
Dialing Properties window opens.
-
Make
sure all settings are correct.
- If you are not using a calling card or call waiting, click to clear the Dial Using Calling Card and Call Waiting check boxes.
|
|
|
Disconnect any answering machine, fax machine, or printer that is on the same line as the modem. You should not have these devices plugged into the same phone line as the modem.
|
|
Make sure that you are not using a digital, rollover, or PBX line. These lines do not work with this 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 phone. 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 phone jack are secure.
You can also call your phone service and have them check the phone
line for noise or low line levels.
|
Try another phone line (either a different phone number in your house, or a phone line at a different location). If you can connect on this line, call your phone company. The other phone line may be too noisy.
|
|
Try connecting with the modem at a lower connection speed. If reducing the connect speed lets you connect, contact your phone company. The phone 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.
Upload speeds (sending data out your computer) are limited to 33.6K.
You can check modem connection speeds and dial-up network (DUN) connections by accessing the gateway.your.way dial-up server. The server also contains drivers, patches, and updates for current Gateway hardware and software.
