I have Fujitsu Lifebook P770 with Windows 7 ultimate x64 installed. Everything works stable without any issues with one exception. If I connect Microsoft Wireless Presenter Mouse 8000 using Microsoft Bluetooth transceiver v3.0 or other BT usb dongles, windows randomly freezes. It happens one time per a few hours - laptop become completely irresponsible, including power button, etc.
This is for sure related with BT - I've never experiencing such problem without the mouse/bt adapter.
Can you please help with troubleshooting?
