No LED Symptom Charts

Note: The LED does not light up when the power is on; however, the LED should pulse when the computer is 

in Sleep mode. 

1.

Put the computer into Sleep mode. Allow the machine to remain in sleep mode for one minute and then 

wake the computer to ensure the computer is waking from sleep mode. Does the LED pulse now? If yes, 

there is nothing wrong with the LED. If no, replace the display bezel (922-5297) shown below. The LED is 

attached to the display bezel and cannot be ordered separately.
