To run POST, complete the following steps:
Turn off the computer, then turn on the computer.

If POST detects errors, the errors are indicated by screen and/or audible messages. Refer to
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.
