Bluetooth stopped working with code 43

[cameo]

Yeap, on my spanking new Lenovo Z400 touch notebook that uses Intel
Centrino BT. After googling this up, I noticed that I am not alone with
this problem and it happens with other brand BT-s as well. Looks like
Microsoft screwed up with a recently released driver and is working on a
fix. Still, it's pretty irritating as I have been using my BT mouse with
it, ironically also sold by MS. Anybody else encountered this problem
recently too?

Your machine is listed here, as using an "Intel Bluetooth driver".
Are you using the version provided by Lenovo ? Well, after looking
at a few more threads, it doesn't look like driver changes do anything
substantial. Based on the size of this porker, there must be
more than drivers in this download. The source of the driver
is likely Intel.

Is it using the N2230 ? It's a single chip based module. And being a module,
in theory it can be replaced with something else. But if you can't get the
product apart to service it, that's out of the question. Then you use a
USB replacement Wifi/BT solution and just disable the internal one. Some
people have been returning their computer, when it turns out the N2230 is
a dud.

I'm guessing the driver is the responsibility of Intel, and they send a
copy to Microsoft. Microsoft may write a Bluetooth stack, but things
like the lower layers, it's up to Intel (for this Intel branded product),
to make sure the plumbing and radio stuff works. For example, that
single chip, may use driver-loaded firmware, and Intel would
be the source of the firmware.

Each of intel patches is a new disappointment cherry,
on top of the everyday cake of exasperation."

The part I consider shocking about all of this, is people are
buying relatively expensive computers, and getting a crappy
unit like that for their Wifi. And imagine buying a computer
in this day and age, and the NIC portion is still 10/100BT ???
What happened to GbE ? It's like the whole connectivity thing
is an afterthought.

And how can these companies put these computers on the market,
when the Wifi demonstrably doesn't work ? Doesn't anyone test
this stuff ?

This is the form factor of that card.

PCI Express Mini Cards are 30*50.95 mm.
A half-length card is also specified 30*26.8 mm

And this picture, shows a product that can bolt into either
sized hole (some sawing required ? )

I also posted my problem on a Lenovo forum and one guy from India
suggested to download the BT driver from an Intel site which fixed the
problem. After all, it's the Intel Centrino Bluetooth 4.0 High Speed
Adapter, so who else should have the authentic driver for it?

If you followed the thread on the Intel site, the Intel tech
support weren't able to help in any substantial way. It's because
one driver update after another, didn't improve matters. I'm surprised
it works for you.

Sorry, I was wrong about it being an Intel site. Actually, it was this
Lenovo site:

http://support.lenovo.com/en_IN/downloads/detail.page?DocID=DS033356

It has links to both the Atheros and the Intel BT drivers and I just
remembered the Intel and I thought that was also referring to an Intel URL.
