Power button LED light not lighting up on DELL Inspiron 5559

 Good question.  I have the same problem with my 4 month old 5559.  The description in the reference guide says "Indicates the power and battery‑charge status.  Press Fn+H to toggle this light between hard‑drive activity light and battery‑status light."  If I press Fn+H, sure enough it shows hard drive activity. 

  Confession time:  I never saw this in the documentation until I looked it up to reply to your question today!  I never knew I had a disk activity light - man, I'm glad to have found this!  :-)

I have the same problem with my new Dell Inspiron 5558. So answer is: There is no LED in power button. Somebody in Dell forgot.. :-D 

aoa ihave the same laptop in under warranty but my power button is little hard to press is it fault or damaged?
