Power LED state
| Description | |
Off |
Power is off, LED is blank. |
Blinking amber |
Initial state of LED at power up. Indicates system has power, but the POWER_GOOD signal is not yet active. If the Hard Drive LED is off, it is probable that the power supply needs to be replaced. If the Hard Drive LED is on, it is probable that an onboard regulator or VRM has failed. Look at the diagnostic LEDs for further information. |
Solid amber |
Second state of the LED at power up. Indicates the POWER_GOOD signal is active and it is probable that the power supply is fine. Look at the diagnostic LEDs for further information. |
Blinking white |
System is in a low power state, either S1 or S3. Look at the diagnostic LEDs to determine which state the system is in. |
Solid white |
System is in S0 state, the normal power state of a functioning machine. The BIOS will turn the LED to this state to indicate it has started fetching operation codes. |
