My PC connects a paired smartphone whenever I reboot PC, and registers itself as headset. And that sucks, because connection drains phone's battery and I don't want to use my PC as headset. Any way to disable this auto-connect? I've got CSR bluetooth dongle and use Windows' built-in drivers.

You need bluetooth headset that support HSP bluetooth.com/English/Technology/Works/pages/hsp.aspx –  user52897 Oct 20 '10 at 3:14
    
As you'll have noticed, without the particular make and model of phone all you'll get is generic answers. Please provide the make and model (and ideally firmware revision if you know it). –  Cry Havok Oct 20 '10 at 6:26

On most phones, you can diable auto-connect by letting it connect then removing the device from the bluetooth list once it is connected.

But I don't want to unpair these devices. –  skevar7 Aug 8 '10 at 12:59
    
It's unpair or autoconnect for 99% of phones. –  JNK Aug 8 '10 at 14:22
    
that can't be true... I never had problem with autoconnect on my previous system. –  skevar7 Aug 9 '10 at 5:44
    
Was it a previous PC or a previous phone? –  JNK Aug 9 '10 at 10:15
    
The same phone, other PC. And WinXP instead of Win7. –  skevar7 Aug 9 '10 at 11:14

What phone is this? On most phones, there's an option under the tools and settings menu to turn off bluetooth entirely.

I don't want to turn it off!!!! I use bluetooth, just don't want it to connect automatically. –  skevar7 Aug 9 '10 at 5:44
    
But if it's on at all, it'll use power. Bluetooth power usage is all-or-nothing. –  digitxp Aug 10 '10 at 1:12

Bluetooth consumes (much) more energy, when it has a working connection (rather than just being turned on and idle) –  skevar7 Aug 15 '10 at 12:13

My current way of doing this seems to work part of the time but it is still the best I've found/come up with so far.

I used autohotkey to create a shortcut (ctrl shift alt b in my case) that disables the bluetooth handsfree // support service. I also created one to open up the sound settings window (ctrl shift alt d) so I can force connect/disconnect as needed. Here is the code (you must create an admin-access shortcut to the .bat as a .lnk file)

.bat:

net stop DeviceAssociationService

net stop bthserv

net stop BthHFSrv

autohotkey (also disconnects top two audio devices in your list):

^!+b:: EnvGet, DROPBOX, DROPBOX ;not necessary - I just share autohotkey scripts across computers and have dropbox stored in different places hence the environment variable

Run %DROPBOX%\Code\Services\utils\batcommands\bstop.lnk ;replace with your .lnk address

Run, mmsys.cpl WinWait,Sound

SetControlDelay -1

ControlClick,X96 Y110,Sound,,R

ControlSend,SysListView321,{Down 3}{ENTER}

ControlClick,X96 Y160,Sound,,R ControlSend,SysListView321,{Down 3}{ENTER}

ControlClick,OK return

^!+d:: Run, mmsys.cpl

return
