Problem Solving
Additional Troubleshooting Procedures
This section provides a more detailed approach to
diagnostic testing and identification of a problem and
locating its source.
Error Checking
Each time you turn on the system, the POST runs
automatically and checks the system board, CPU
module, memory, keyboard, and most installed
peripheral devices.
If POST finds an error, it displays an error message
and, in case there is a problem with the display, puts
out a series of long and short beeps. One short beep
means the system passed POST. Refer to the BIOS
User’s Information section in this chapter for a list of
items to check for each error code and for an
explanation of the error beep codes.
Troubleshooting Guide
Use the following troubleshooting procedures to help
you identify a problem. These general procedures lead
you through the following:
■ Preparing the system for diagnostic testing
■ Monitoring POST while it is running
■ Verifying proper operation of key system LEDs
■ Confirming loading of the operating system.
