Power-On Self Test
The notebook performs the Power-On Self Test (POST) every time you turn on or
reset the notebook. The POST is a series of system checks that verifies the correct
operation of your notebook's hardware.
If the POST detects a critical error (e.g., a system board failure), the notebook will halt
and generate an audible alarm. If a failure is detected in an area other than the system
board (such as the keyboard), a non-critical error message is displayed on the screen
and testing is stopped. You can continue testing when a non-critical error occurs by
pressing F1.
When the POST encounters an error that requires you to correct something, either a
beep code will sound or a message will be displayed in a box in the middle of the
screen. If you need to enter the Setup Utility to correct a problem press F2.
Otherwise, press F1 to continue the boot process and ignore the error.
