Dell Precision 390 Blinking Power Light

This question has suggested answer(s)

Hi,  whilst trying to install a new mouse the computer restarted.  and niw it wont turn back on, the power light is continously blinking amber and no mater how I press the button it will  not turn on.  Unfortunatly i am unable to locate the full manuel and only have the quick refrence guide which points to Power Management in the full manuel. I have tryed leaveing the unit unplugged but as soon as I plug it back in the blinking continues.

Can any one suggest a solution??


Thanks in advance

    When turned on, what color are the Diagnostic Lights?

  • Hi Chris, 

    None of the Diagnostic lights light up,  just the power light which is orange



  • Possible power surge / supply problem, try leaving power cord off, check voltage at wall or loose connectors
