To run POST, complete the following steps:
Turn off the computer, then turn on the computer.
1.
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).
2.
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.
3.
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.
