Power LED

Table 1. Power LED . The power LED states are shown in following table.

  • Hibernate or Suspend to Disk (S4).
  • Power is off (S5).
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 opcodes.
Blinking White Turns on steadily or blinks to indicate battery charge status.

Single Diagnostic LED

This platform does not ship with legacy diagnostic LEDs which utilized the storage, power and wireless LED as a diagnostic LED. It is now relying on the Battery LED light blinking amber/white pattern to determine failures listed in the following table.
  • NOTE: The blinking patterns will consist of 2 set of numbers being represented by (First Group:Amber blinks, Second Group:White blinks)
    • First Group : The LED blinks 1 to 9 times followed by a brief pause with LED off at the interval of 1.5 seconds. (This is in Amber color)
    • Second Group : The LED blinks 1 to 9 times, that would be then followed by a longer pause before the next cycle starts again at the interval of 1.5 seconds. (This is in White color)

Example: No Memory detected (2,3), Battery LED blinks two times of amber color followed by a pause, and then blinks three times of white color. The Battery LED will pause for 3 seconds before the next cycle repeat itself again.

Please see New Error Code Standardization eLearning for more information.

The following table depicts the amber and white blinking patterns with possible troubleshooting resolution:
