Bluetooth Blues on Lenovo?

This is one of those posts that I write to bookmark some useful stuff.

I have a Windows 7 based Lenovo laptop at work and recently got a wireless Bluetooth mouse to use. It works great but for this weird problem to stop responding every so often to any movement whatsoever. I’ve noticed this happens regularly when I get back to the PC after a coffee break and sometimes even when I’m actively working on the laptop but not using the mouse.

Naturally I suspected the Bluetooth service and looked around task manager to see if it was behaving abnormally – but no dice. SO I hunted around a bit online and it looks like its a pretty common problem with Thinkpads, something that Lenovo does to its Bluetooth service is not right(of course, this is purely based on the number of complaints I came across online by Lenovo owners; it might be an issue with other laptops too). After some more digging I came across this post – Bluetooth mouse losing connection no more.

Like the author of that post, I too did not benefit from Microsofts KBA. In my case the second point worked,

opened up Device Manager, expanded “Bluetooth Radios”, and double-clicked on the device to open its Properties page – not the enumerator, the device.

BTDeviceManager

Double click the device (highlighted), not the enumerator
Go to the Power Management page and clear the checkbox “Allow the computer to turn off this device to save power”. And finally, relief! No more disconnects. Apparently there is a bug in the power management of the Bluetooth driver under Windows 7.

BTPowerManagement

Uncheck ‘Allow the computer to turn off this device to save power’

So next time you have the same problem, try this out.
