Troubleshooting Your Computer

You can troubleshoot your computer using indicators like Diagnostic Lights, Beep Codes, and Error

Messages during the operation of the computer.

Diagnostic LEDs

NOTE: The diagnostic LEDs only serve as an indicator of the progress through the Power-On Self
Test (POST) process. These LEDs do not indicate the problem that caused the POST routine to stop.

The diagnostic LEDs are located on the front of the chassis next to the power button. These diagnostic
LEDs are only active and visible during the POST process. Once the operating system starts to load, they
turn off and are no longer visible.

Each LED has two possible states of OFF or ON.

NOTE: The diagnostic lights will blink when the power button is amber or off, and will not blink
when it is white.
