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. |
