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. 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.
The following table shows dierent light patterns and what they indicate.
