So the LCD on my 9100 failed about a month ago.  I figured it was the backlight since I could still see a very faint image when the computer was on in a dark room and it also worked fine when connected to an external monitor.  Called around, no one would fix it...even if I told them what it was.  I even bought my own backlight for $10.  Couldn't get everything back together and working properly like it should and even ended up breaking the backlight itself.  Ended up getting a replacement LCD online (not from Dell since this is out of warranty).  It's actually an LCD from an old Inspiron 8600.  I simply swapped the hinges in from my 9100 and it works great but I have two "extra" cables from the 9100 itself with no matching cables from the LCD.  I'll explain...

 

This new LCD doesn't have any "antennae cable" that connects to the computer itself.  In other words, my 9100 has a black cable and a white cable that Dell calls "antennae cables" (see this page:  http://support.dell.com/support/edocs/systems/ins9100/sm/display.htm#1006390).  These cables emerge from somewhere under the keyboard and come out right near where power connector is (i.e., near where the power on/caps lock/etc LED's are.  There is a matching pair of cables that runs down the inside of the LCD cover (i.e., if the laptop is closed, just under the plastic piece you're looking at).  They run from near the top of the lid down to the bottom where they are supposed to connect with the pair from the computer itself.  At the top of the lid on my 9100, these cables are in and have a sticker on them that says "Hitachi Cable, Ltd", "HFT08-DL01-Aux(A00)", "HAS-03-249", and "08-Dec-03".  I was wondering what purpose these cables serve.  The only thing I thought it could be was for wireless or something.  The new 8600 LCD that I've got hooked up now doesn't have these cables on the lid but still seems to be working fine.  I think I can swap in my 9100 lid for the 8600 so I can connect these mystery cables but am wondering if I really need to and what these cables are actually supposed to do.  I hope I wasn't too confusing in my explanation.  Any assistance is greatly appreciated.
