TROUBLESHOOTING

Power-On Self Test (POST)

POST is a series of diagnostic tests that run automatically when the system is turned on. After the

computer is turned on, POST checks the following assemblies to ensure that the computer system is

properly functioning:

■ Keyboard

■ System board

■ Memory modules

■ Video memory

■ Diskette drives

■ Hard drive

■ Power supply

POST also detects the type of mass storage devices installed in the computer.

If POST finds an error in the system, an error condition is indicated by an audible and/or visual

message. The table below gives explanations of the error codes and a recommended course of action.

NOTE: An external speaker must be installed into the speaker output connector to

hear audible beeps during POST.
