Here is an example of DELL diagnostic lights
***DELL System Diagnostic Lights***
The power-status light indicates the power status of the computer.
These are the power states:
***Solid white***                         Computer is in S0 state. This is the normal power state of the computer.
***Blinking white***                  Computer is in a low-power state, S3. This does not indicate a fault.
***Solid amber***                       Computer is experiencing a boot failure, including the power-supply unit.
***Blinking amber*** Computer is experiencing a boot failure but the power-supply unit is functioning correctly.
***Off***                                         Computer is in sleep state, hibernation mode, or turned off.
*  The power-status light may also blink ***amber*** or ***white*** according to predefined "beep codes" indicating various failures.
* For example, the power and battery-status light blinks ***amber*** two times followed by a pause, and then blinks ***white*** three times followed by a pause.
* This 2,3 pattern continues until the computer is turned off, indicating no memory or RAM is detected.

Amber blinking? That means the power supply is good, according to DELL.

Unplug power supply/charger. Take out the battery and and press the power button to dischage any power. After that is done, with the battery uninstalled, plug in the charger. Press power button. Does anything happen? Any flicker on the screen, beeps or lights. Describe.
