Power-on self-test

Whenever the computer is turned on, the power-on self-test (POST) routine test various hardware components, including memory, and compares the actual configuration of the computer with that recorded in configuration (CMOS) memory. During this time, BIOS sign-on and POST messages are displayed.

A configuration discrepancy could arise if you have just installed or removed a hardware option (for example, if you have added or replaced a SIMM). In this case you may be prompted to invoke the BIOS Setup utility.

If POST detects a hardware fault, one or more POST error codes and messages are displayed (see table opposite). You may also be prompted to “Press the F1 key to continue” or “Press any key when ready”. The computer may be able to continue despite the error indication (for example, if a memory chip fails POST, the computer can continue with less memory).

♦Your first action should be to turn off the computer, wait at least 30 seconds, and then turn it on again to see if the error is transient or persistent. Persistent POST errors may indicate a fault in the system.

♦Check that all external cables are securely connected.

♦Try running the BIOS Setup utility to reconfigure the system.

♦Open up the system unit and check that all internal signal and power cables are securely connected.

If the problem persists, call your supplier or authorized maintainer.
