okey dokey :emotion-5:

have actually reported this issue directly to Dell and provided all possible information along as well.

I haven't heard anything from Dell for a few months now, and I definitely don't think it's because they've solved it :emotion-9:

I find it rather hard to understand why they can't just offer an old (functioning) module in stead

That's it in a nutshell,getting someone at Dell to listen, isn't it? I've reported this issue to "managers" at customer service, "managers" at tech support ad infinetum and no response. If Dell is selling defective equipment knowingly,then this needs to get escalated past this board.

I have had this exact same issue with multiple E6400 and E6500's.  I have had about 8 of these since release.   I swap my laptop out with a new one often and every one will randomly drop the BT370 module while listening to A2DP audio.  I have 3 different sets of BT headphones and they all cause it. 

I do not have to go in the BIOS and disable BT to get it working again.  I have to completely power down the laptop and restart. 

If I plug in a BT USB dongle everything picks right up where it left off and never drops like the BT370 module.

Someone at Dell needs to fix this!

I have a very similar problem.  I use a Precision M4400 with the 370 module.  I don't normally use the BT function but I leave it on anyway.  It didnt bother me until this recently.  The module would connect and then disconnect suggesting some kind of hardware failure.  Even reinstalling the drivers do not help.  Currently I am running w/o the drivers and there is a very noticeable lag when typing or using the mouse etc.  This is happens when the bluetooth light comes on.  The only way to get rid of the lag is to go into the BIOS and DISABLE the bluetooth module. So it's definitely the module in my view, not the drivers.  Of course switching it off would defeat the purpose of having it.

I would suggest Dell users to stay away from the internal module and if it is a must, they should consider other brands.

Hello,

I'm also facing the same issue with an M11x laptop.

I'm using it only for a mouse, but since few day, when I was playing, I was facing a lot of lags.

Now since few hours; the module is not anymore in the device manager, and I've try to do your methode (first post) but it's not working for me.

I have 365 module.

Did some body have some news?

Sorry for my bad english (french guy spoted!!)

I have the same exactly the same problem with CHARTREUSE

My laptop is studio 1558 & 365 module, too.

Almost the same...

Using mouse for  1hr-->a lot of lags ,and also can't detect another bluetooth device --> the mouse can only click but can't move--> checkoccur device manager and find error alert  --> reboot -->still occur error alert in device manager

I doubt this is hardware malfunction but not driver problem.

Did anyone face the same problem and solve it?

Pls tell me how.

Have similar problem with Studio 1747.   64 bit ................original windows 7.....

Dell has attempted to resolve this problem, but to no avail.

Dell "blames" it on the Windows 7 updates and their inability to keep up with these changes.  While there is some truth in this, they have not been

forthcoming on these issues.

Sorry.

Bumping this old thread in hopes someone has a fix. I have a year old AW m11x with a 365 module that crapped out on me 2 months ago. I've been living without it but it would be awesome to be able to use my much more responsive (and expensive) BT mouse rather than this wireless USB.

Yes I've been through the support forums and ran through all of the troubleshooting advice. I can't seem to get any farther than that through the various channels. I agree that it seems to be a Windows 7 support issue since the failure seemed to nicely coincide with 7 service pack 1 install. Anyone have any advice?

Thanks!

Yes I've been through the support forums

I know I suggested before for folks to post on the Laptop General Hardware forum, but now my suggestion is to post on the Networking/Internet/Wireless Board.  There are a couple of regulars there who know more about Bluetooth connectivity.

I know this is the laptop forum, but I can tell you that this BT problem is endemic with any machine the things are installed in.

I have recently (2 weeks ago) had a Dell XPS 8300 desktop delivered with the 365 BT card. This lasted all of 2 days before it bombed out, and no amount of fiddling with it will make it work.

I'll have to sort this out under warranty, but I think in future something USB pluggable and cheap will probably do the job as well if not better than this unreliable Broadcomm thing.

My Vostro V13 has the same issues.. I tried the newest drivers from different sources. Updated the firmware of BT. Still sometimes it works for 3mins, sometimes 30mins. Then disappears from Device Manager. Sometimes comes back on after a restart. I cannot say. But the BT led stays on always. If i turn the wireless (Fn+F7) off and then back on, it may show up sometimes. My A2DP stereo headset is laughing at me....
