   be in the cable or    
   in the modem/router. And, check the board. That jack may have been strained at   
   some point and broken a solder connection - especially if there are   
   cats/dogs/small children involved. I would very much hesitate to spray   
   anything at all into a jack - as    
   anti-corrosives such as DeOxit continue to react until all the materials have   
   been 'used up' - which could do considerable and fatal damage to a   
   mother-board. If you are _EXCEEDINGLY_ careful, you might try 91% (or more)   
   alcohol on a small brush or small    
   cotton swab - but the potential for collateral damage is high without that   
   extreme care.

   I tried using a modified pencil eraser over the connections and, no,   
   they didn't look out of place or corroded as far as I could tell.  Yes,   
   I tried switching out the cables to known good ones to no avail.   
      
   Since the charger board, which contains the USB, charger and ethernet   
   ports can be removed and replaced, I have another one here I could try   
   or simply order a known good one.  I've been wanting to try one anyway   
   since I have another laptop here that won't respond as I have been   
   suspecting the charger board.   
      
   Thanks for the tips, however.
