Windows 10: Bluetooth Issue on my Windows 10, Lenovo Z400 Laptop

Hello there.


I have my issue regarding my Bluetooth connection on my laptop. It can't detect any device and it doesnt discoverable either.


My Bluetooth info on Device Manager:

- Bluetooth Device RFCOMM Protocol TDI

- Microsoft Bluetooth Enumerator

- Qualcomm Atheros AR3012 Bluetooth 4.0


These items are there since i reinstalled my Windows.


I have ticked Discoverable checkbox on the bluetooth options too.

So how to fix it?


Thank you.

:)

brightness issues on my ideapad z400 touch

I am running Windows 10 64 bit on my Lenovo Z400 and the registry edit below worked for me. I am also running the latest Intel 4000 graphics driver that I downloaded and installed from here:

https://downloadcenter.intel.com/product/81499/Intel-HD-Graphics-4000-for-3rd-Generation-Intel-Core-Processors I installed the driver first but not sure if that is important. Hopefully a windows update does not mess any of this up.

Registry Edit Steps:

• Press the Windows key + R to open the run
• Type "regedit" to edit the windows registry
• Search for "FeatureTestControl" through the search:
  
  or go on the path: /HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Control/C
• Double-click on the FeatureTestControl, open the box to edit. Change the Value data field to:
  F00F or FFFF (FFFF worked for me)
• Close regedit and restart your computer.

I got the registry edit information from here.

Bluetooth in windows 10

My computer specs are as listed in the profile. I think all of you guys are correct. I don't have built-in Bluetooth in mobo.

I contacted skull candy headphones and thy have told me if I do not have built-in Bluetooth, I would need a dongle which supports at least a2dp. I do not know what the heck that means. I have a feeling I would need more than a cheap dongle.

Anyone suggest some a2dp adapters. I searched but don't know what a2dp is so couldn't make a decision
