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 <F1>.
