Power-On Self-Test (POST)
Each time you turn on your computer, it performs a series of tests that check the
operation of the base computer. This series of tests is called the power-on self-test
(POST).
Note
If your computer starts but does not boot when you press the power switch, do
the following:
� Make sure all cables are securely connected to the correct locations.
� Check to see if the voltage-selection switch is set to the correct position for
your country.
For additional information, see Setting Up Your IntelliStation E Pro.
POST does the following:
� Checks basic system-board operations
� Checks the memory operation
� Compares the current system configuration with that established by the
Configuration/Setup Utility program
� Starts the video operation
� Verifies the presence of diskette drives, hard disk drives, and the CD-ROM
drive (if installed)
