Solving Problems

Troubleshooting Tips

Perform the following checks when you troubleshoot your computer:

• If you added or removed a part before the problem started, review the installation procedures

and ensure that the part is correctly installed.

• If a peripheral device does not work, ensure that the device is properly connected.

• If an error message appears on the screen, write down the exact message. The message may help

technical support personnel diagnose and fix the problem(s).

Beep Codes

Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems.

This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1) consists

of one beep, a burst of three beeps, and then one beep. This beep code tells you that the computer

encountered a memory problem.

If a beep code is emitted, write it down and look it up in the following table.

1-1-2 Microprocessor register failure

1-1-3 NVRAM read/write failure

1-1-4 ROM BIOS checksum failure

1-2-1 Programmable interval timer failure

1-2-2 DMA initialization failure

1-2-3 DMA page register read/write failure

Error Messages

NOTE: If the message is not listed, see the documentation for either the operating system or the program that was

running when the message appeared.

If an error occurs during start-up, a message may be displayed on the monitor identifying the problem.

See "Error Messages" in the

User’s Guide

for suggestions on resolving any problems.

Diagnostic Lights

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located

in the Product Information Guide.

To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4" on the front.

The lights can be off or green. When the computer starts normally, the lights flash. After the computer

starts, all four lights display solid green briefly and then turn off to indicate normal operation. If the

computer malfunctions, the pattern of the lights identify the problem.
