My bluetooth stopped working about 2 weeks after I got the W510. I have uninstalled and reinstalled the Bluetooth 2.1 with EDR software several times but it still will not detect any bluetooth devices. I know the hardware is working, because I have the W510 set up with a dual-boot Ubuntu installation, and the Lenovo Bluetooth Laser Mouse is detected immediately when I use that instead of Windows 7. Has anyone else had a similar problem? Any tips for getting it working?

Check in the device manager in the properties of USB hub if the bluettoth is powered properly.
What exactly happens ? can you turn it on or not at all ?

Er, sorry, how do I try to turn on the power from the device manager?
If I look at the generic USB hub properties (the one with BT attached) I see:
HID-compliant mouse - 100mA required
Thinkpad Bluetooth 2.1 - 0mA required
USB composite device - unknown
the last one is the webcam, I believe

What's happen when you press Fn+F5 ?

If I press Fn+F5 I get the display as expected. Bluetooth shows as powered on; I can power it on and off from the OSD and the green light under the screen reacts as expected - but nothing will persuade it to find any devices!

I have the same thing going on but with a new W520. Finds devices for a couple days then stops finding devices and cannot pair to the computer from another device (my phone) though it is discoverable there. When I go back to the Lenovo OKR image from the recovery partition, it starts working again.
When it eventually stops working there are no errors in device manager, the BT radio is on, all appears like it should be working but it doesn't. This is on a Windows 7 x64 Pro OKR image (upgraded to Ultimate). It is a perplexing and annoying issue.

What does "OKR" stand for?
