Diagnostics The computer POST (Power On Self Test) ensures that it meets the basic computer requirements and the hardware is working appropriately before the boot process begins.

The computer POST (Power On Self Test) ensures that it meets the basic computer requirements and the hardware is working
appropriately before the boot process begins. If the computer passes the POST, the computer continues to start in a normal
mode. However, if the computer fails the POST, the computer emits a series of LED codes during the start-up. The system LED
is integrated on the Power button.
