Re: Bluetooth problem on ThinkPad

All the drivers are up to date (new BIOS, new embedded controller, and
everything else). ThinkPad update and Microsoft Update have no more updates,
patches, drivers, hotfixes . . . nothin.

Dr: Stop poking yourself in the eye with a sharp stick

Summary: Bluetooth works on 5 laptops. Bluetooth stops working on every
laptop that a new driver is installed to.
Conclusion: The driver broke Bluetooth on these computers.

Did you miss a step, such as?
Do you need a BIOS flash in order for these new drivers to access the
port correctly?
Do you need to update the Motherboard drivers in order for these new
drivers to access the port correctly?

Hello

I have a problem with the built-in Bluetooth on my Lenovo ThinkPad T43
laptop (in fact, laptops: I have five identical computers of this type).

The ThnnkPad Software Installer suggested I uninstall the old version of
the
Bluetooth driver, which I did, and install a new "Enhanced Data Rate
verions"
. . . which I did.

Once I installed the new drivers, I could not use Bluetooth. The blue/red
icon tray icon and the My Bluetooth Places items show up (ThinkPad
technical
support said this is no longer the correct way to access Bluetooth in
SPT).
But (despite the radio being switched on), I get the error "No local
Bluetooth device was detected" whenever I try to run anything like
"Bluetooth
Setup Wizard" or the like.

The blue/white icon tray Bluetooth icon (which I was told is the supported
way to access Bluetooth in SP2) doesn't show up normally, and there is
*no*
"Microsoft Bluetooth Enumerator" device in the Device Manager.

I have tried (numerous times) to rectify this by going to the Device
Manager, selecting the ThinkPad Integrated Bluetooth IV device and
updating
the driver (as identified as the correct one by ThinkPad support). Once I
do
this, the blue/white icon shows up in the tray, and the Microsoft
Bluetooth
Enumerator device shows up in the Device Manager--*BUT ONLY BRIEFLY*.
There,
in front of my eyes, in 5-10 seconds, they both disappear from the screen.

I have uninstalled and reinstalled the software a number of times, but I
keep getting the same result. I am virtually certain this is not a
hardware
problem, as (a) it wasn't happening before the latest software update; and
(b) it is occurring on all the computers that I have updated. I am running
XP
Pro SP2 and have *all* the latest driver updates.

Any ideas?

Tx & rgds
