Let stand for a 10 count, then turn the computer back on. If POST does not detect any errors, the computer will not beep. This indicates successful completion of POST test.

If POST detects errors, the errors are indicated by screen and/or audible messages. Refer to "Power-On Self-Test (POST) Codes" 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 not NOTE: functioning well enough to show POST error messages, refer to the Troubleshooting tables.
