Power-On Self Test (POST)

Running POST

To run POST, complete the following steps:

●Turn off the computer; then, turn on the computer.

●If POST does not detect any errors, the computer will not beep. This indicates successful completion of POST test. POST has run successfully and boots from the hard drive (or from a bootable 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 relevant descriptions.

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

Troubleshooting tables.
