[Solved] M900 Bluetooth connection problem

I have a M900 10NE Tiny with latest BIOS and Drivers which doesn't find Bluetooth devices. Neither with the Windows Bluetooth tool nor with the "Lenovo Bluetooth Lock".

The Bluetooth-Device is visible in the device manager. For test purpose I plugged in a old Bluetooth dongle which work without problems.

 

Can anybody give me some hints? Is it possible that's a hardware problem, BIOS settings?

 

Environment:

M900 10NE Tiny

Windows 10 Pro 64bit

Bluetooth Driver:

- Date: 29.9.2016

- Version: 19.11.1639.649

Re: M900 Bluetooth connection problem

I really don't know why and how I came to this solution but it worked.

When you open the case you can see on the front left side the wires for Bluetooth and Wifi. On my M900 the two wires for Main and Aux where connected in the wrong order. After inverting the order of the two cables, Wifi and Bluetooth worked without problems.

In the picture you can see the correct wiring.
