I have a Microsoft Keyboard Elite for Bluetooth and Microsoft Intellimouse Explorer for Bluetooth. I can pair both up with my Lenovo Thinkpad T60p without the use of the dongle. The mouse will always come back to life after a couple of click or moving it around. The keyboard however, doesn't respond after a period of time and does not reconnect on reboots. It will still show up in the bluetooth application, and if I hit a key it will show that it is connected. But i get no output from the keyboard unless I remove it, twice, from the bluetooth application and re-pair it with my laptop. This is extremely frustrating and I hope someone can offer a solution that will help. I have tried the blueman application as well, but in the end the keyboard responded the same way.
