Bluetooth failing after sleep, ThinkPad Edge S430, W8

Hi,

 

Whenever I sleep the system, afther that Bluetooth won't work anymore. I have to make a total system shutdown, turn on, and maybe it works. Sometimes I have to remove the Bluetooth device and after a second restart it will work again.

 

The only error I get (from the event viewer) is:

"The local adapter does not support an important Low Energy controller state.  The minimum required supported state mask is 0x1f7fffff, got 0x1f3fffff.  Low Energy functionality will be disabled."

  </Event>

 

Device manager will just put an exclamation mark and disable it because "it stopped working".

 

My system comes with Intel Centrino Wireless-N 2230 & Bluetooth 4.0 (2x2 BGN & BT4). I'm using the latest Bluetooth driver available (2.6.23.40059) but I've also tried with the default driver and the previous version available from Lenovo Support site.

 

Honestly, I haven't been using sleep too much. So I didn't pay much of attention and I just found out this weekend. But looking at the event viewer, I see that it never worked, since two months ago that I acquired the computer.

 

Ideas?

 

Thanks!

Bump. Nothing regarding this? Am I the only one experiencing this issue? Smiley Frustrated
