Problems since installing Toshiba bluetooth stack drivers

[Page]

Since installing the Toshiba blue tooth stack driver on my Sony FE11S I have a problem with the cpu usage in idle state hovering around the 50% mark. There seem to be various processes contributing to this with the main one being tosobex.exe.

If I disable blue tooth in the wireless device switch the problems remains until I do a restart after which - with no bluetooth running - it has gone away.

I followed the upgrade procedure on the sony download site.
I have checked that I have the latest drivers.

Is anyone else having this same problem.

Does anyone have any ideas on how to resolve it as I would like to have bluetooth running.

I'm having the same problem since weeks. I don't know what this could be. I tried almost all possibilities, like older Toshiba Bluetooth Stack drivers, manual registry and file system cleaning and thousands of driver reinstalls. Nothing worked. But in my case the failing process is TosBtMng.exe which runs with 50% CPU usage (means 100% for one core of the core duo).

This week I made a phone call to the Vaio support. Not the best support I ever had. The result of this call: "you have to reinstall your system". Congratulations Sony - this notebook is in a productivity environment and can't be reinstalled right now just for fun. And who ensures that the bluetooth stack will work after reinstall?

I think it should be any other installed software that causes this malfunction. But which? I'm trying to uninstall some relevant applications and look, what's going on.

FYI: My notebook is a VGN-SZ2XP/C running Windows XP SP2.

Please if anybody else has this problem let us know.

Sorry that you are having the same problem but then also pleased it is not just me.

You sound as if you have more technical skills than me. If so this link may be of help.

It finishes with a solution but for a different computer. If you can understand it then perhaps give it a go and let me know how you get on and if need be I will have to do a little bit of learning.

Good Luck

And in case they help some other links that I had found before I decided to abandon the project for a while.

Thank you for these links. If I have the time I'm looking forward to review your research results.
BTW: The technical support of the VAIO team called me last week to talk about any other possibilities to solve the problem. But we didn't get to any conclusion. The bluetooth stack thing is pretty complex and deeply integrated into the Windows registry.

Ah - I had best go no where near it then.

That is a curse.

There only seem to be you and me so far with this problem and on this forum. Though my guess is that many people do not use bluetooth with their PC nor this forum so there may be many others out there thinking that their laptop is not as nippy as it used to be.

Did anyone ever solve this problem?

Anyone got any ideas

I can't believe that no one else has had this problem.

No one ?
