Flickering Bluetooth "blue light" going bad?

In the last day or so, I have noticed the little blue light for the Bluetooth card over my keyboard has been mostly out, but does quickly flash on and/or flicker from time to time. 

Here's what I have tried so far...

The card is seated firmly in it's place.  
I do NOT get the Windows noise that says the device is attached/missing when it goes on and off , so I can only assume it is still working poperly.
I reinstalled the Bluetooth drivers.
I re-flashed the BIOS.  (saw that in a similar thread as a culprit)

I still have the problem.   I don't have any bluetooth devices yet, so I cannot confirm that it is still operating or if it is just the light.   In cracking open the case, the light is a part of the main board, so changing out just the light probably isn't an option.

It doesnt affect anything, so it's no big deal.   But I really liked that blue light. 

Any ideas or similar phenominon out there?

    Gregg600m,


    It may just be the light going bad or a loose connection or it could be the card is going bad or the connector on it or the motherboard is faulty. Until you have a bluetooth device to test it with I wouldn't worry about too much.



    Thank you for choosing Dell.

    Sometimes...I have to stop and start my 8500 when it's coming up ( just as it's getting to the BIOS Post screen ) because the Blue light doesn't come on. After a couple of stops and starts, it comes up. I've noticed it off and on, and wondered if it's not a USB detection thing.....because.....I've noticed also, that if I have BOTH usb ports occupied when I boot the laptop, it won't detect Bluetooth...no matter how many times I power on and off during POST. I did some digging around in the registry and the device list, and came to realize that the bluetooth module in the 8500 ( and presumably the D800's ) is ...ta-da...USB-based. So......any insights on what could be happening ??

    Well...here's alittle extra info on my problem.

    I've notices that when I swivel thescreen to a different angle, this also causes it to come on momentarily, so I am leaning towards it being something loose.

    I'm gonna crack it open again and double-check the seating of the card. 

    But if the card were coming lose, wouldn't I get that "ding ding" and system tray icon that Windows XP does when it recognizes components being added or taken away?

    If it's the light going bad, that means a whole motherboard replacement, huh?   Because the light is a tiny LED sunk intothe board itself with a plastic tube routing the glow up to the little window by the hinge.

    I have the same problem....it is either the Bluetooth card itself or the motherboard....a technician is coming to day to swap the module on my laptop...

    My 600m is still brand new....just got it 2 1/2 weeks ago....everything works fine...except for the bluetooth...

    I was talking to Dell Wireless support (located in the US)...you get transfered to them regardless of which initial tech answers your call(US or India)...and we went through all the standard fixes....but the problem is that the module goes in and out of being recognized...so he scheduled a repair...

    My Bluetooth also functions intermitantly and if you go in the BIOS you will see that it will randomly list the Bluetooth module as either "Installed" or "Not Installed". Same thing in windows....it will randomly detect the card as well(i'll post screen shots in another post)

    I am also wondering if the A05 Bios update had anything to do with it....cause my laptop shipped with A02 and the card worked fine with it...the card only started "flickering" after I upgraded the BIOS...anyone have a copy of the A02 BIOS?

    See...  but that's not my problem.   The Bluetooth stays recognized.  I don't get the ding ding or the bubble saying it's recognized, then gone.  

    I think that my light is just going mad.

    My 8500 has a similar problem. The blue light is off and only flashes once upon cold boot. The bluetooth still functions though. Any ideas?

    Thanks

    If you still have a warrenty have it fixed berfore it expires!!!

    I thought mine was just a issue with the LED but it turned out to be a problem with the module connecting to the motherboard...

    Thats my only advice to you....

    I totally agree if the Bluetooth light isn't functioning....you lose an important indicator to whether or not your bluetooth is functioning properly...

    My Bluetooth has been replaced twice along with my Motherboard (because the connector on the MB was physically broken)....so you should have support fix the problem...

    TWICE???

    What is wrong with Dell???

    Why can't they fix the issue once and for all with them MB?? Obviously it is a common problem.....

    I'm afraid once I do get my system back it will be just a matter of time before it breaks again.. At that time the system may not be under warrenty!
