Bluetooth Problem.

Question

Hi, everyone!   I have purchased a Dell Inspiron E1705 less than 15 days ago and I ran into the problem which makes me a little unhappy. First of all, I discovered that turning Bluetooth off makes the processor go into C3 state and laptop makes a high-pitched sound. Which is normal. I have a good hearing, so it makes me . I decided to stay with Bluetooth turned on. Everything is OK, but sometimes bluetooth icon turns red and then to white again, while the laptop's Windows makes the sound of 'Hardware Connected', 'Hardware Disconnected', 'Hardware Failed to connect'. These three Windows exclamations sound probably once every hour, depending on what I am doing.   Can you please tell me if it's normal and what I can do to stop that. Consider when I give presentations and my computer makes these sounds - it's pretty uncomfortable. However, option of Disabling bluetooth is not a good idea, because of a quiet, but hearable by me, high-pitched noise. And I think it is Bluetooth that makes this - because when I turn it off, it never happens. What is it and how can I resolve it?   Thank you very much!   Eugene.   P.S.: I am a first-time user, so if there are messages about that, can you plz give me the links?

Hi Eugene, I have pretty much the same problem. Last night I thought I had it solved but it's still a problem. I've had this system just about 2 weeks and like you I see the Windows Device manager 'lose' the Dell Wireless 355 Module from the list - 'ding' gone then 'ding' back again sometimes in rapid succession. Dell support have not been succesful at fixing this. We've tried a new internal module, reinstall drivers, stack and software and even a complete restore - pretty much everything. At one point they sent me the 350 module (by accident!) and that worked fine. I still have that module for a few more days before I ship it back. I 'suspect' that there is a an updated driver from broadcom (who make the BT module) - If I can't get this resolved in the next week, I'll be returning this E1705/9400. This has been a frustrating experience. So take heart you're not alone. So what is the solution guys!?!

I don't think I would get to the point of wishing to return my new laptop just because of this little Blue Tooth module. It doesn't happen too often - maybe once or twice a day now. But, yeah, assume that you're giving a presentation which would change your life and the dinging would start... I really have no idea, but it appears to me that the bluetooth is more stable when there are no bluetooth devices in range and when I am not using the programs that have the potential of transmitting information through Bluetooth. It might be just me. I had a problem of Bluetooth always waking my laptop up from the Stand By, but I resolved this problem by changing the setting in the BIOS that allowed USB device to wake the computer up.   Also, does anyone observe this thing: when the laptop starts and the screen turns black and then shows Welcome Screen, or any other time when the monitor is refreshed, you can see a little wave going from any part to the top right corner. I may assume that it is just the liquid crystals being refreshed and the little visible wave forms due to the electic charges. So is it normal?   Thanks everyone for your help.   Eugene.
