Preliminary Steps

Before running POST, complete the following preliminary steps:

1. If a power-on password has been established, type the password and press the Enter key. Ifthe password is not known, clear the password.

2. Run Computer Checkup.

3. Turn off the computer and its external devices.

4. Disconnect any external devices that you do not want to test. Do not disconnect the printer ifyou want to test it or use it to log error messages.

IMPORTANT:

If the problem only occurs when an external device is connectedto the computer, the problem may be related to the externaldevice or its cable. Verify this by running POST with and withoutthe external device connected.

5 Install loopback plugs in the serial and parallel connectors if you would like to test these ports

Turn off the computer, then turn on the computer.

If POST does not detect any errors, the computer will not beep. This indicates successfulcompletion of POST test. POST has run successfully and boots from the hard drive (or from abootable diskette if one is installed in the diskette drive).

If POST detects errors, the errors are indicated by screen and/or audible messages. Refer to"Power-On Self-Test (POST) Codes" in the tables for a list of POST codes and their relevantdescriptions.

NOTE:If the system is not functioning well enough to run POST, or if the display is not functioningwell enough to show POST error messages, refer to the Troubleshooting tables.

Electrostatic Discharge

A sudden discharge of static electricity from a finger or other conductor candestroy static-sensitive devices or microcircuitry. Often the spark is neitherfelt nor heard, but damage occurs. An electronic device exposed toelectrostatic discharge (ESD) may not be affected at all and will workperfectly throughout a normal cycle. Although, it may function normally for a

while, then degrade in the internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but inmany cases, the discharge contains enough power to alter device parametersor melt silicon junctions.

Generating Static

The table shows how different activities generate static electricity and atdifferent electrostatic voltage levels.

Most cables used throughout the unit are ribbon cables. Cables must be handled withextreme care to avoid damage. Apply only the tension required to seat or unseat thecables during insertion or removal from the connector. Handle cables by the connectorwhenever possible. In all cases, avoid bending, twisting, or tearing the cables, andensure that the cables are routed in such a way that they cannot be caught or snaggedby parts being removed or replaced.

C a b l e s
