Power on Self Test Error Messages
The laptop performs the Power-On-Self-Test (POST) every time
you turn on or reset the system. The POST is a series of system
checks that verifies the correct operation of your laptop’s
hardware.
If the POST detects a critical error (for example, a system board
failure), the laptop halts and generates an audible alarm. If a failure
is detected in an area other than the system board (such as the
keyboard), a noncritical error message appears on the screen and
testing is stopped. You can continue testing when a noncritical
error occurs by pressing
