I have a user who just recieved a new wireless Microsoft Bluetooth mobile keyboard 5000. When I hook it up it does not discover it. I have used hardware devices to locate new hardware. The light on the keyboard comes on then blinks from green to red. from what I have read it means it cannot find the keyboard. I have remoived all bluetooth devices and re-booted and still it cannot find the keyboard but it does see the wireless mouse? I have downloaded all bluetooth drivers again from Lenovo as this is a Lenovo X201 laptop.
