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

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,
or if the display is not functioning well enough to show
