1.4. Standard Test Features
The Extensa 67x Series Notebook Computers use modular design and built-in test features to
reduce the mean time to repair.
1.4.1 Power On Self Test
The Extensa line of notebook computers contain a BIOS-resident, Power On Self Test (POST) that
automatically performs a test of memory and all major circuits each time the computer is powered
up. In the event of a failure, the computer displays a descriptive error message and issues a series
of coded beeps (in case the display subsystem is not functioning). If self test completes normally,
the computer displays the amount of memory tested, loads the Operating System and Windows
environment.
