POST error codes
Each time you turn on the system, it performs a series of tests that checks the operation of the system and
options. This series of tests is called the power-on self-test, or POST.
The POST performs the following operations:
• Checks some basic system board operations
• Checks the memory operation
• Checks the video operation
• Verifies that the boot drive is working
If the POST detects a problem, an error message will be displayed on the screen. A single problem can
cause several error messages. When you correct the cause of the first error message, probably the other
error messages will not be displayed the next time you turn on the computer.
