Power Lights

The two-color power-button light located on the front of the computer illuminates and blinks or remains solid to indicate different states:

•If the power light is off, the computer is either turned off or is not receiving power.

•If the power light is steady blue and the computer is not responding, ensure that the display is connected and powered on.

•If the power light is blinking blue, the computer is in standby mode. Press a key on the keyboard, move the mouse, or press the power button to resume normal operation. If the power light is blinking amber, the computer is receiving electrical power, a device such as a memory module or graphics card might be malfunctioning or incorrectly installed.

•If the power light is steady amber, there may be a power problem or an internal device malfunction.

Beep Codes

Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems. This series of beeps, called a beep code, identifies a problem. One possible beep code consists of repetitive three short beeps. This beep code tells you that the computer encountered a possible motherboard failure.
