Power-On Self Test (POST)

Running POST

To run POST, turn off the computer, then turn it back on.

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 the following tables for a list of POST codes and their relevant descriptions. If there is more than one recommended action, only try the later actions in the list if the first action recommended does not solve the problem.

If the system is not functioning well enough to run POST, NOTE: or if the display is not functioning well enough to show

POST error messages, refer to the Troubleshooting tables.
