I use a Lenovo Thinkpad Bluetooth Laser Mouse with my Thinkpad x130e and Quantal. It works without problems as long as the notebook is on AC-Power. When it runs on battery the mouse works for some minutes or half an hour an suddenly it stops working and I must reboot to get it work again.
What is different with the bluetooth connection when running on battery and can it be changed? I guess it must have something to do with power saving functions.
Thanks for your help.
PS: I just found
This looks as if there could be the solution for the problem but I'm not good at reading such scripts.
