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